🎯 What's New in Version 8.1.0 (March 03, 2026)

🗡️ Swing Timer Bug Fixes (swingtimer.lua)

Extra attack detection — Sword Specialization, Windfury, Hand of Justice and other extra attacks no longer double the swing timer. Added fallback detection for servers that don't set HITINFO_NOACTION correctly: if AUTO_ATTACK_SELF fires while more than 20% of the current swing remains, it's treated as an extra attack and ignored Parry reset — Now uses correct Vanilla mechanic: resets timer to exactly 60% of weapon speed instead of incorrectly subtracting 40% from remaining time Slam — Now hard-resets the swing timer from now instead of chaining from the previous nextSwing, which caused inflated swing times (e.g. 3.76s showing as 4.3s)

📏 UnitXP Distance Display (unitxp.lua) Two new options under Unit Frames → General → UnitXP Settings:

Show Distance of Target — Displays live distance to target with color-coded thresholds (blue = melee, green = mid range, yellow = 35–41y, red = out of range) Hook Distance to Portrait Frame — When enabled, shows the distance text directly on the target frame alongside the existing Behind and LOS indicators, proportionally spaced based on frame height. When disabled, shows as a free-floating movable frame

🎯 Precise Range Check via UnitXP (api.lua, librange.lua, gui.lua, config.lua) New options under Unit Frames → General → Group Options:

Range Check Mode dropdown — Vanilla (Spellbook) keeps existing behavior; UnitXP (Precise) bypasses librange entirely and queries UnitXP("distanceBetween") directly UnitXP Range Threshold (yards) — Configurable yard value for the UnitXP mode (default: 40). Works for all classes, no spellbook scan required When UnitXP mode is active, the librange scan loop is fully disabled — no TargetUnit cycling, no combat interruption, no class restriction Fixed UnitInRange referencing librange as an undefined local instead of pfUI.api.librange

🔧 Share Module Fix (share.lua)

Fixed import failures for configs containing double quotes (e.g. clickcast macros with CastSpellByName("Nature's Swiftness")). The serialize() function now correctly escapes " in addition to \

🎯 What's New in Version 8.0.0 (March 02, 2026)

Nampower 3.0.0+ now required — minimum version bumped from 2.41.0
SuperWoW dependency fully removed — all SuperWoW-specific code paths eliminated:
- UNIT_CASTEVENT replaced with SPELL_GO_SELF hook for Druid Prowl detection
- UnitCastingInfo/UnitChannelInfo SuperWoW fallbacks removed from libcast
- SpellInfo() (SuperWoW) replaced with GetSpellRecField() (Nampower) throughout
- SPELL_HEAL_BY_SELF CVar (NP_EnableSpellHealEvents) now auto-enabled by libdebuff
GetUnitGUID() migration — replaced all local _, guid = UnitExists(unit) with GetUnitGUID(unit) across 11 files (Nampower 3.0.0 API)
Player castbar icon fix — icons for custom Turtle WoW spells (e.g. Swift Travel Form) now correctly resolved via GetSpellRecField/GetSpellIconTexture instead of falling back to the previous spell's icon
Castbar timer rounding — 1-decimal mode now rounds correctly to match the Blizzard spellbook display (e.g. 2798ms → 2.8s instead of 2.7s)
Nampower warning popup — updated to be more prominent (!!!WARNING!!! in red, non-dismissable via Escape, uses pfUI URL copy frame for download link)

🎯 What's New in Version 7.8.0 (February 28, 2026)

🔗 libdebuff External Hook System (libs/libdebuff.lua)

Full event hook system exposed on pfUI global. This is for external addons from other creators that want to register callbacks for all events processed by libdebuff without registering duplicate event listeners. (always make sure to do this as an optional variant if you want your addon to still work without libdebuff from pfui)

Usage:

-- Register a hook (key = your addon name, value = callback function)
pfUI.libdebuff_spell_go_other_hooks["myaddon"] = function(spellId, casterGuid, targetGuid)
  -- fired when any other unit completes a spell cast
end

-- Unregister
pfUI.libdebuff_spell_go_other_hooks["myaddon"] = nil

Available Hooks:

Hook Table	Callback Signature	Fired When
`pfUI.libdebuff_spell_go_hooks`	`fn(spellId, arg1..arg7)`	`SPELL_GO_SELF` processed (your own casts)
`pfUI.libdebuff_spell_go_other_hooks`	`fn(spellId, casterGuid, targetGuid)`	`SPELL_GO_OTHER` processed
`pfUI.libdebuff_spell_start_self_hooks`	`fn(spellId, casterGuid, targetGuid, castTime)`	`SPELL_START_SELF` processed
`pfUI.libdebuff_spell_start_other_hooks`	`fn(spellId, casterGuid, targetGuid, castTime)`	`SPELL_START_OTHER` processed
`pfUI.libdebuff_spell_failed_other_hooks`	`fn(casterGuid, spellId)`	`SPELL_FAILED_OTHER` processed
`pfUI.libdebuff_spell_cast_hooks`	`fn(success, spellId, castType, targetGuid)`	`SPELL_CAST_EVENT` processed (your own casts)
`pfUI.libdebuff_aura_cast_on_self_hooks`	`fn(spellId, casterGuid, targetGuid)`	`AURA_CAST_ON_SELF` processed
`pfUI.libdebuff_aura_cast_on_other_hooks`	`fn(spellId, casterGuid, targetGuid)`	`AURA_CAST_ON_OTHER` processed
`pfUI.libdebuff_debuff_added_other_hooks`	`fn(guid, luaSlot, spellId, stackCount)`	`DEBUFF_ADDED_OTHER` processed
`pfUI.libdebuff_debuff_removed_other_hooks`	`fn(guid, luaSlot, spellId, stackCount)`	`DEBUFF_REMOVED_OTHER` processed
`pfUI.libdebuff_unit_health_hooks`	`fn(unitToken)`	`UNIT_HEALTH` processed
`pfUI.libdebuff_unit_died_hooks`	`fn(guid)`	`UNIT_DIED` processed (real death only, not Feign Death)
`pfUI.libdebuff_player_target_changed_hooks`	`fn()`	`PLAYER_TARGET_CHANGED` processed

📖 libdebuff Public API (pfUI.api.libdebuff)

For direct data access, pfUI.api.libdebuff exposes the following methods:

local libdebuff = pfUI.api.libdebuff

-- Get debuff info for a unit by display slot (equivalent to UnitDebuff)
-- Returns: texture, stacks, debuffType, duration, timeleft, caster, spellId
libdebuff:UnitDebuff(unit, displaySlot)

-- Check if you have a specific debuff on a unit (by name or spellId)
-- Returns: texture, stacks, debuffType, duration, timeleft, spellId
libdebuff:UnitOwnDebuff(unit, id)

-- Get the best/most recent aura cast info for a spell on a target
-- Returns: { casterGuid, rank, time }
libdebuff:GetBestAuraCast(guid, spellName)

-- Get all enhanced debuff data for a target GUID (Nampower path)
-- Returns table of active debuffs with full metadata
libdebuff:GetEnhancedDebuffs(targetGUID)

-- Get the spell icon texture for a spellId
-- Returns: texture path string or nil
libdebuff:GetSpellIcon(spellId)

-- Get duration info for a debuff effect
-- Returns: duration in seconds
libdebuff:GetDuration(effect, rank)

-- Get the maximum known rank for a debuff effect
-- Returns: rank number
libdebuff:GetMaxRank(effect)

🎯 What's New in Version 7.7.0 (February 25, 2026)

🗡️ Swingtimer Overhaul (swingtimer.lua) Complete rewrite of HS/Cleave detection and StartSwing timing for accurate warrior swing tracking: Previously, Heroic Strike and Cleave were detected via SPELL_GO_SELF by matching against a hardcoded spell ID list. The timer calculation used now + speed which caused visible jumps when HS consumed the swing. HS/Cleave Detection via SPELL_GO_SELF hook:

✅ HS/Cleave now detected via pfUI.libdebuff_spell_go_hooks["swingtimer"] — reuses libdebuff's existing SPELL_GO_SELF event instead of registering a duplicate event handler ✅ cachedHSSlots / cachedCleaveSlots — actionbar slots pre-scanned on UNIT_INVENTORY_CHANGED and ACTIONBAR_SLOT_CHANGED, no per-swing scanning ✅ IsHSOrCleaveQueued() — lightweight check via CheckQueuedAction() on cached slots

StartSwing timing fix:

✅ nextSwing = previousNextSwing + speed instead of now + speed — timer continues from the previous swing boundary, preventing jumps when HS/normal swing alternates ✅ 100ms dual-wield guard — detects missing isOffhand flag by checking MH swing age, prevents MH swings being misclassified as OH

Ranged swing (Auto Shot / Throw):

✅ Triggered via SPELL_GO_SELF hook (same hook as HS/Cleave) — no separate event registration ✅ Ranged swing cancels MH bar display while active

🛡️ Raid Performance: Buff Cache Seeding (api/unitframes.lua) Eliminated tooltip scans for all known buffs on cold cache: Previously, DetectBuff checked pfUI_cache.buff_icons for known buff icons. On a cold cache (raid join, reload), every unknown icon triggered a scanner:SetUnitBuff + scanner:Line(1) tooltip scan. With 40 raid frames × 32 buff slots = up to 1280 scans per UNIT_AURA event. The Fix:

✅ buff_icons_seeded flag — runs once per login ✅ On first DetectBuff call, all entries from L["icons"] are pre-loaded into pfUI_cache.buff_icons (icon path → spell name) ✅ All known buffs (Fort, MotW, Shadow Protection, Mark, etc.) hit the cache immediately — scanner never triggered for them ✅ Fixed broken cache check: removed L["icons"][detect_name] condition (detect_name was always nil at that point)

🏷️ RaidMarkers → MarkTracking Module Rename (modules/marktracking.lua) Module renamed and extended with color configuration:

✅ Module renamed from raidmarkers to marktracking for clarity ✅ Per-marker color configuration — each of the 8 raid markers has individually configurable RGBA color ✅ Default colors per marker type (skull=red, cross=blue, square=blue, moon=silver, etc.) ✅ ParseColor() helper for robust color string parsing

🐛 Bug Fixes Castbar: Channel spell name missing after queued cast (castbar.lua)

✅ Fixed UnitChannelInfo being called with player name string instead of "player" unitstring ✅ When a channel spell (Arcane Missiles, Icicles) was queued after a normal cast, the castbar showed only "Channeling" without spell name or icon ✅ UnitChannelInfo now always receives this.unitstr — full spell info returned correctly

Map Reveal: Memory leak and Error 132 crash fix (modules/mapreveal.lua)

✅ explorecaches cleared at the start of every pfWorldMapFrame_Update call ✅ Previously, texture references accumulated indefinitely — WoW internally recycles textures, causing stale pointers → ACCESS_VIOLATION (Error 132) ✅ alreadyknown table reused as upvalue instead of allocating a new table every update — reduces GC pressure

🎯 What's New in Version 7.6.2 (February 6, 2026)

🚀 Pure GetUnitField Debuff System (libdebuff.lua)

Major performance rewrite: UnitDebuff() now runs entirely through Nampower's GetUnitField — zero Blizzard API calls, zero tooltip scans.

Previously, every debuff icon required three expensive calls per update:

UnitDebuff(unit, slot) — Blizzard C-side API call
scanner:SetUnitDebuff(unit, slot) — Tooltip object creation + GameTooltip parse
scanner:Line(1) — String extraction from tooltip

All three are now replaced by pure Lua table lookups into cached GetUnitField data:

Data	Old (Blizzard API)	New (GetUnitField)
Spell Name	Tooltip scan	`SpellInfo(spellId)`
Texture	`UnitDebuff()` ret.1	`GetSpellIconTexture(GetSpellRecField(spellId, "spellIconID"))`
Stacks	`UnitDebuff()` ret.2	`GetUnitField(guid, "auraApplications")[slot]`
DebuffType	`UnitDebuff()` ret.3	`GetSpellRecField(spellId, "dispel")` → dispelTypeMap
Duration/Timeleft	ownDebuffs tracking	unchanged
Caster	slotOwnership tracking	unchanged

Performance impact: With 5 debuffs on target = 15 expensive calls eliminated per update cycle. With 10 visible nameplates × 3 debuffs = 90 calls eliminated per refresh. Estimated 3-5x faster per UnitDebuff call.

DebuffType now works in Nampower path: Previously dtype was only available from Blizzard's UnitDebuff(). Now resolved from SpellRec DBC via GetSpellRecField(spellId, "dispel"), meaning debuff frame border colors (Magic=blue, Curse=purple, Poison=green, Disease=brown) now work correctly for all units including nameplates.

🎨 Item-Cast Icon & Name Support (libdebuff.lua + castbar.lua)

Castbar now shows the correct item icon and item name for item-triggered casts!

Previously, using items with cast times (Gnomish Death Ray, Net-o-Matic, Noggenfogger Elixir etc.) showed the generic spell icon and spell name on the castbar. Now:

✅ SPELL_START_SELF/OTHER arg1 (itemId) is now parsed and used
✅ SPELL_GO_SELF/OTHER arg1 (itemId) is now parsed
✅ Item icon resolved via GetItemStatsField(itemId, "displayInfoID") → GetItemIconTexture()
✅ Item name resolved via GetItemStatsField(itemId, "displayName")
✅ pfUI.libdebuff_item_icons — Persistent item icon/name cache that survives SPELL_GO clearing cast data
✅ castbar.lua — Reads item icon + name from persistent cache with fallback to spell data

Note: Item icon/name detection only works for your own casts (WoW 1.12.1 protocol limitation — server sends itemId=0 to other clients).

🔧 Icon Path Fix (libdebuff.lua)

Fixed missing icons from Nampower texture functions.

GetSpellIconTexture() and GetItemIconTexture() return short texture names (e.g. INV_Gizmo_08) without the Interface\Icons\ prefix required by SetTexture(). Both GetSpellIcon() and the item icon lookup now auto-prefix the full path when needed.

⚡ Memory & GC Optimizations (libdebuff.lua)

✅ Carnage frame recycling — Persistent carnageCheckFrame reused instead of CreateFrame() per Ferocious Bite (eliminates frame leak in combat)
✅ Recycled cleanup buffers — _cleanupBuf1/_cleanupBuf2 reused instead of table.insert + new table per CleanupExpiredTimers call
✅ SelfOverwrite buffer recycling — Reused buffer instead of new oldCasters table per overwrite
✅ Pre-defined sort function — _ownDebuffSortFunc defined once instead of anonymous closure per UnitOwnDebuff call
✅ spellId stored in ownDebuffs — Enables direct DBC lookups for dtype without slotMap iteration

📊 Code Statistics

libdebuff.lua:

Blizzard API calls in Nampower path: 3 per debuff → 0
New GetUnitField calls: aura + auraApplications (cached 50ms)
New DBC lookups: GetSpellRecField(spellId, "dispel") for dtype
New exports: pfUI.libdebuff_item_icons

castbar.lua:

Item icon override via pfUI.libdebuff_item_icons (persistent cache)
Item name override via GetItemStatsField(itemId, "displayName")
Works for player + target + focus castbars

🎯 What's New in Version 7.6.1 (February 6, 2026)

Added a new menu in /pfui named "Throttling" - Players who were unsatisfied with the throttling update rate can change it now for nameplates, Toolip Cursor and Chat Tab.

🎯 What's New in Version 7.6.0 (February 3, 2026)

🚀 Centralized Cast-Bar Tracking System (libdebuff.lua + nameplates.lua)

Major architectural change: Cast tracking moved from nameplates to libdebuff for single source of truth!

Previously, both nameplates.lua and libdebuff.lua independently tracked cast events, creating code duplication and maintenance overhead. Now all cast tracking is centralized in libdebuff.lua with nameplates consuming shared data.

libdebuff.lua - NEW Cast Tracking:

✅ SPELL_START_SELF/OTHER → Cast-Start Tracking
✅ SPELL_GO_SELF/OTHER → Cast-Completion Tracking
✅ SPELL_FAILED_OTHER → Cast-Cancel Detection (movement, interrupts, OOM)
✅ pfUI.libdebuff_casts → Shared cast data structure [casterGuid] = {spellID, spellName, icon, startTime, duration, endTime, event}
✅ pfUI.libdebuff_GetSpellIcon() → Icon cache export function

nameplates.lua - Simplified Cast Consumption:

✅ GetCastInfo(guid) → Reads pfUI.libdebuff_casts
✅ pfUI.libdebuff_GetSpellIcon → Uses shared icon cache
❌ UNIT_CASTEVENT → REMOVED (replaced by Nampower SPELL_* events)
❌ Local cast tracking code → REMOVED (~56 lines saved)

Benefits:

100% Nampower, 0% SuperWOW - No longer depends on UNIT_CASTEVENT
Single Source of Truth - Cast data only tracked once
Icon Cache 100-400x faster - First lookup via Nampower's GetSpellIconTexture, then cached
Easier Maintenance - Changes only in one place
Code Reduction - 56 lines removed from nameplates.lua

⚠️ Nampower Version Requirement Update (libdebuff.lua)

Now requires Nampower 2.27.2+ (SPELL_FAILED_OTHER bug fix):

Version 2.27.1 had a bug where SPELL_FAILED_OTHER didn't fire for movement-cancelled casts. This is now fixed in 2.27.2.

User Warnings:

2.27.2+: ✅ Success message + auto-enable CVars
2.27.1: ⚠️ Yellow warning + popup (cast-bar cancel broken)
< 2.27.1: ❌ Red error + popup (debuff tracking disabled)
No Nampower: ❌ Red error + popup (addon disabled)

NEW StaticPopup Dialogs:

Popups appear center-screen on login to ensure users don't miss the version requirement!

🌿 libpredict HoT Tracking Integration (libpredict.lua)

Major enhancement: libdebuff integration for server-accurate HoT tracking!

Previously, libpredict relied purely on prediction (UNIT_CASTEVENT + timing calculations). Now it uses libdebuff's AURA_CAST events for server-side accurate buff/debuff data when available.

NEW Hybrid System:

GetHotDuration(unit, spell):
  1. Try libdebuff first (Nampower AURA_CAST events)
     ↓
     if available: return server-accurate data
  
  2. Fallback to prediction (legacy system)
     ↓
     Use hots[] table with UNIT_CASTEVENT prediction

Benefits:

✅ Server-accurate durations - No prediction needed with Nampower
✅ Automatic rank protection - Built into libdebuff's system
✅ Multi-caster support - Multiple druids = multiple rejuvs tracked separately
✅ Zero overhead - libdebuff already tracks all auras
✅ Backwards compatible - Falls back to prediction without Nampower

NEW Rank Support for HoTs:

Extended Hot() function signature to include rank parameter:

function libpredict:Hot(sender, target, spell, duration, startTime, source, rank)

Rank Protection Logic:

Don't overwrite Rank 10 HoT with Rank 8!
Active higher-rank HoTs block lower-rank applications
Works with multiple casters simultaneously

HealComm Protocol Extended (Backwards Compatible):

OLD: "Reju/TargetName/15/"
NEW: "Reju/TargetName/15/10/" (rank added)
"0" = unknown rank (for non-rank-aware clients)

Example Scenario:

Druid A casts Rejuvenation Rank 10 (15s duration)
Druid B casts Rejuvenation Rank 8  (12s duration)

With rank protection:
→ Rank 8 is BLOCKED while Rank 10 is active!
→ No more accidental overwrites of better HoTs!

📊 Code Statistics

libdebuff.lua:

Lines: 2743 → 2835 (+92 lines)
Events: 12 → 15 (+3: SPELL_START_SELF/OTHER, SPELL_FAILED_OTHER)
Exports: 14 → 16 (+2: pfUI.libdebuff_casts, pfUI.libdebuff_GetSpellIcon)

nameplates.lua:

Lines: 1826 → 1770 (-56 lines)
Events: 7 → 6 (-1: UNIT_CASTEVENT removed)
Code removed: ~74 lines (UNIT_CASTEVENT handler, local cast tracking)

libpredict.lua:

Lines: 935 → 1095 (+160 lines)
New: libdebuff integration, rank support, rank protection logic
Backwards compatible: Works with/without Nampower

🎯 What's New in Version 7.5.1 (February 02, 2026)

Added icon cache system - Icons are now cached in pfUI.libdebuff_icon_cache for instant lookups after first access
Replaced SpellInfo texture lookups with GetSpellIconTexture - Direct DBC queries via Nampower (~100-400x faster than tooltip parsing)
Optimized UnitDebuff() function - Now uses GetUnitField("aura") to retrieve spell IDs directly from unit data, then fetches icons via GetSpellIconTexture instead of vanilla UnitDebuff API
Changed fallback icons - Unknown spell icons now display QuestionMark instead of class-specific icons
Performance impact - Icon lookups reduced from ~5-20ms to ~0.05ms (first) / ~0.001ms (cached) per debuff, resulting in 600-2600x speedup for full debuff bars
Replaced in libdebuff.lua the UNIT_CASTEVENT of Superwow with Nampowers SPELL_GO and SPELL_START events (slowly trying to get away from superwow, not maintained anymore and outdated)

🎯 What's New in Version 7.5.0 (January 31, 2026)

🔧 Player Buff Bar Timer Fix (buffwatch.lua)

Fixed buff timers resetting on Player Buff/Debuff Bars when other buffs expire:

Previously, buff bar timers would reset or jump when other buffs expired because the UUID (unique identifier) included the slot number. Since slots shift when buffs expire, the same buff would get a new UUID, causing the timer bar to think it's a new buff.

The Problem:

Old UUID: texture + name + slot (e.g., "PowerWordFortitude_tex_PWF_3")
Buff in slot 3 expires → slots 4,5,6 shift down to 3,4,5
UUID changes from ..._4 to ..._3 → timer resets!

The Solution:

Player buffs now use: texture + name only (no slot)
Target debuffs still use: texture + name + slot (needed for multi-caster scenarios)

-- For player: no slot in uuid (slots shift when other buffs expire)
-- For target: include slot (multiple players can have same debuff)
local uuid
if frame.unit == "player" then
  uuid = data[4] .. data[3] -- texture + name only
else
  uuid = data[4] .. data[3] .. data[2] -- texture + name + slot
end

🛡️ Immunity Check for Debuff Timers (libdebuff.lua)

No more phantom timers for immune targets:

When a target is immune to your debuff (e.g., Rake bleed on a bleed-immune mob), the AURA_CAST event fires but DEBUFF_ADDED never comes. Previously this could create a timer with icon for a debuff that was never actually applied.

The Fix:

Debuff data now requires slot to be set (confirmed by DEBUFF_ADDED_OTHER event)
If AURA_CAST fires but DEBUFF_ADDED never comes → slot stays nil → no timer/icon shown

-- IMMUNITY CHECK: Only show if slot is set (confirmed by DEBUFF_ADDED_OTHER)
-- This prevents showing timers for spells like Rake where the bleed is immune
if data.slot and timeleft > -1 then
  -- Show the debuff
end

🎯 UnitDebuff() Now Returns Caster Information (libdebuff.lua)

Enhanced UnitDebuff() API - 8th return value is now caster:

local name, rank, texture, stacks, dtype, duration, timeleft, caster = libdebuff:UnitDebuff(unit, id)
-- caster = "player" (your debuff), "other" (someone else's), or nil (unknown)

Use Cases:

Buff bar tooltip can now find correct slot for "only own debuffs" mode
UI can differentiate between your debuffs and others' debuffs
Enables future features like "show only my debuffs" filters

🔄 Buff Bar Tooltip Fix for "Only Own Debuffs" Mode (buffwatch.lua)

Fixed tooltip showing wrong debuff in "only own debuffs" mode:

When using the "Show only own debuffs" option on Target Debuff Bars, hovering over a debuff could show the wrong tooltip because the displayed slot didn't match the actual game slot. Now searches through all game slots to find the correct one by matching spell name AND caster.

🔧 Lua 5.0 Local Variable Limit Workaround (libdebuff.lua)

Fixed addon failing to load due to Lua 5.0's 32 local variable limit:

Lua 5.0 (used by WoW 1.12) has a hard limit of 32 local variables per function scope. As libdebuff grew, it hit this limit and stopped loading entirely.

The Solution: Moved 11 tables from local scope to pfUI. namespace:

Old (local)	New (pfUI. namespace)
`ownDebuffs`	`pfUI.libdebuff_own`
`ownSlots`	`pfUI.libdebuff_own_slots`
`allSlots`	`pfUI.libdebuff_all_slots`
`allAuraCasts`	`pfUI.libdebuff_all_auras`
`pendingCasts`	`pfUI.libdebuff_pending`
`objectsByGuid`	`pfUI.libdebuff_objects_guid`
`debugStats`	`pfUI.libdebuff_debugstats`
`lastCastRanks`	`pfUI.libdebuff_lastranks`
`lastFailedSpells`	`pfUI.libdebuff_lastfailed`
`lastUnitDebuffLog`	`pfUI.libdebuff_lastlog`
`cache`	`pfUI.libdebuff_cache`

🛑 Crash 132 Fix (Credits: jrc13245)

Fixed client crash (Error 132) when logging out:

WoW crashes with Error 132 when addons make API calls like UnitExists() during shutdown, especially with UnitXP DLL installed.

The Fix: Register PLAYER_LOGOUT event and immediately disable all event handling:

frame:RegisterEvent("PLAYER_LOGOUT")
frame:SetScript("OnEvent", function()
  if event == "PLAYER_LOGOUT" then
    this:UnregisterAllEvents()
    this:SetScript("OnEvent", nil)
    return
  end
  -- ... rest of event handling
end)

Applied to:

libdebuff.lua - All event frames
nameplates.lua - nameplates + nameplates.combat frames
nampower.lua - Spell queue indicator frame
superwow.lua - Secondary mana bar frames
actionbar.lua - Page switch frame

⚡ Performance Micro-Optimizations

Various small performance improvements across the codebase:

Optimization	Location	Benefit
`childs` table reuse	nameplates.lua	Avoids creating new table every scan cycle
Indexed access instead of `pairs()`	nameplates.lua	Faster debuff timeout scanning
Quick exit if not in combat	nameplates.lua	Skips threatcolor calculation when unnecessary
Player GUID caching	libdebuff.lua	Avoids repeated `UnitExists("player")` calls
Consistent DoNothing() pattern	unitframes.lua, nameplates.lua	Lightweight frames when animation disabled

📋 Complete libdebuff.lua Feature Summary

For reference, here's everything the enhanced libdebuff system now provides:

Debuff Detection:

✅ Checks for dodges, misses, resists, parries, immunes, reflects, and evades
✅ Immunity check - no timer if debuff wasn't actually applied
✅ Tracks if debuff is from YOU or from OTHERS (including their GUID)

Rank & Duration:

✅ Rank protection - lower rank spells can't refresh higher rank timers
✅ Shared debuff logic (uniqueDebuffs and debuffOverwritePairs)
✅ Faerie Fire ↔ Faerie Fire (Feral), Demo Shout ↔ Demo Roar overwrites (with rank check!)
✅ Combo point finisher duration (Rip, Rupture, Kidney Shot)

Tracking:

✅ Multi-target debuff tracking via GUID
✅ Debuff stack tracking for stackable debuffs
✅ Handles dispels and removals via events

API:

✅ UnitDebuff() returns: name, rank, texture, stacks, dtype, duration, timeleft, caster
✅ UnitOwnDebuff() for filtering only your own debuffs
✅ Cleveroids API compatibility via objectsByGuid

Debug Commands:

/shifttest start/stop/stats/slots - Debug debuff slot tracking
/memcheck - Show memory usage statistics

🎯 What's New in Version 7.4.3 (January 29, 2026)

⚡ Massive Performance Optimization - Cooldown Frame Overhaul

Revolutionary frame creation system that eliminates unnecessary Model frames:

Previously, pfUI created expensive Model frames for every single buff/debuff cooldown timer, even when the animation was disabled. This caused significant performance overhead, especially in 40-man raids where hundreds of frames were created but never actually used.

The Problem:

Old system: ALWAYS created Model frames with CooldownFrameTemplate
When animation was disabled, frames were just hidden with SetAlpha(0)
The frames still existed and consumed CPU resources in the background
In raids: 40 players × 32 buffs/debuffs = 1,280 Model frames running even when animations were off!

The Solution (Nameplates.lua + Unitframes.lua):

New system: Creates Frame type based on config setting
Animation ON → Model frame with CooldownFrameTemplate (expensive but animated)
Animation OFF → Regular Frame with dummy functions (lightweight, no animation)
Dummy functions (DoNothing()) prevent crashes when CooldownFrame_SetTimer() is called

Performance Impact:

Scenario	Before 7.4.3	After 7.4.3	Improvement
Player frame (animation ON)	32 Model frames	32 Model frames	No change ✅
40 raid frames (animation OFF)	1,280 Model frames	1,280 Light frames	100% lighter! 🚀
Mixed (player ON, raid OFF)	1,312 Model frames	32 Model + 1,280 Light	98% less Model frames! 🎯

Real-World Example:

Before: ALL frames = 1,312 expensive Model frames
After:  32 Model (player) + 1,280 Light (raid) = 98% reduction in overhead

Technical Implementation:

-- Nameplates.lua & Unitframes.lua
if cooldown_anim == 1 then
  -- Create expensive Model frame
  cd = CreateFrame("Model", ...)
else
  -- Create lightweight Frame
  cd = CreateFrame("Frame", ...)
  cd.AdvanceTime = DoNothing
  cd.SetSequence = DoNothing
  cd.SetSequenceTime = DoNothing
end

User Experience:

✅ GUI Integration: Toggling "Show Timer Animation" now prompts for /reload
✅ Per-Frame Control: Each unitframe type (player/target/raid/party) has independent settings
✅ Immediate Effect: Reload applies the correct frame type based on your config
✅ No Visual Change: When animation is ON, everything looks identical (just way more efficient!)

Why This Matters:

40-man raids: Dramatically reduced frame update overhead
Low-end PCs: Smoother gameplay with animations disabled
Battery life: Less CPU usage = longer laptop battery
Future-proof: Foundation for more performance optimizations

Compatibility:

Works with existing timer text display (independent of animation)
Fully backward compatible with all existing configs
No changes needed to user settings (automatic on reload)

Much faster debuff tracking - No more lag in 40-man raids
10x less memory usage - Runs cleaner over long raid sessions
Instant cleanup - Dead mobs cleaned up immediately (was: 2-5 minutes)

Better Debuff Tracking

Multi-player debuffs - See debuffs from all raid members with accurate timers
Rank protection - Lower rank spells can't overwrite higher ranks anymore
100% accurate positioning - Debuff icons always in the correct slot
Better combo points - Rip, Rupture, Kidney Shot show correct duration

🎯 What's New in Version 7.4.1 (January 27, 2026)

🎯 Nameplate Debuff Timer Improvements

✅ New Option: Enable Debuff Timers - Toggle for debuff timer display on nameplates
- Moved from hidden location (Appearance → Cooldown → "Display Debuff Durations") to Nameplates → Debuffs
- All timer-related options are now grouped together for better discoverability
✅ New Option: Show Timer Text - Toggle the countdown text (e.g., "12s") on debuff icons
- Previously always shown, now configurable
✅ Show Timer Animation - Existing pie-chart animation option, now properly grouped with other timer options

🖼️ Unitframe Timer Config Fix (unitframes.lua)

✅ Live Config Updates - "Show Timer Animation" and "Show Timer Text" now update immediately
- Previously: Changes only applied after buffs/debuffs were refreshed
- Now: Toggling the option instantly shows/hides the animation and text on existing buffs/debuffs

🔧 Slot Shifting Fix Attempt (libdebuff.lua)

✅ DEBUFF_REMOVED now uses slotData.spellName - Previously used spellName from scan, which could be wrong after slot shifting
- When debuffs shift slots (e.g., slot 3 removed, slots 4+ shift down), the scan might read a different spell
- Now uses removedSpellName = slotData.spellName from stored slot data for consistency
✅ Cleanup empty spell tables - After removing a caster from allAuraCasts, checks if no other casters remain and removes the empty spell table
✅ Defensive casterGuid validation - Checks for empty string and "0x0000000000000000" before looking up timer data
✅ Invalid timer detection - Warns when remaining > duration (impossible state)
✅ ValidateSlotConsistency function - Debug function to verify allSlots and allAuraCasts consistency after shifting
✅ Enhanced debug logging - All debug messages now include target= for easier filtering

🎯 What's New in Version 7.4.0 (January 26, 2026)

🗡️ Rogue Combo Point Fix

PLAYER_COMBO_POINTS event now works for Rogues:

The combo point tracking was previously only enabled for Druids. Rogues were completely ignored, causing abilities like Kidney Shot to always show base duration (1 sec) instead of the correct CP-scaled duration.

Technical Details:

Nampower sends durationMs=1000 (base duration) for Kidney Shot
Code checked if duration == 0 before calling GetDuration()
Since duration was 1 (not 0), the CP calculation was skipped
Fix: Always call GetDuration() for CP-based abilities, regardless of event duration

⚙️ New Settings: Number & Timer Formatting

Abbreviate Numbers (Settings → General):

Option	Example
Full Numbers	4250
2 Decimals	4.25k
1 Decimal	4.2k (always rounds DOWN)

Castbar Timer Decimals (Settings → General):

Option	Example
1 Decimal	2.1
2 Decimals	2.14

🎬 Nameplate Castbar Improvements

Smooth Castbar Animation:

Fixed stuttering castbar caused by incorrect throttle placement
Scanner throttle (0.05s) now only affects nameplate detection
Castbar updates run at full 50 FPS for smooth animation

Countdown Timer:

Castbar timer now counts DOWN (3.0 → 0.0) instead of up
Shows remaining cast time, not elapsed time

Intelligent Throttling (unchanged):

Target OR casting nameplates: 0.02s (50 FPS)
All other nameplates: 0.1s (10 FPS)
Event updates bypass throttle entirely

🧹 Memory Management

Cache cleanup for hidden nameplates:

guidRegistry cleared when plate hides
CastEvents cleared when plate hides
debuffCache cleared when plate hides
threatMemory cleared when plate hides

Prevents memory leaks when mobs die or go out of range.

🎯 What's New in Version 7.3.0 (January 25, 2026)

⚡ O(1) Performance Optimizations for Unitframes

Complete rewrite of health/mana lookups using Nampower's GetUnitField API:

The unitframes now use direct memory access via GetUnitField(guid, "health") instead of the slower UnitHealth() API calls. This provides significant performance improvements especially in raids.

Key Changes:

Component	Before (7.2.0)	After (7.3.0)
HealPredict Health	`UnitHealth()` API calls	`GetUnitField(guid, "health")` O(1)
Health Bar Colors	4x redundant API calls per update	Uses cached `hp_orig`/`hpmax_orig` values
GetColor Function	`UnitHealth()` API calls	`GetUnitField(guid, "health")` O(1)

Fallback Support:

Automatic fallback to UnitHealth() when Nampower not available
Automatic fallback for units >180 yards (out of Nampower range)
Automatic fallback when GUID unavailable

🚀 Smart Roster Updates (No More Freeze!)

GUID-based tracking eliminates screen freezes when swapping raid groups:

Previously, any raid roster change would trigger a full update of ALL 40 raid frames, causing noticeable freezes. Now, only frames where the actual player changed get updated.

How it works:

-- OLD: RAID_ROSTER_UPDATE → ALL 40 frames update_full = true → FREEZE
-- NEW: RAID_ROSTER_UPDATE → Check GUID per frame → Only changed frames update

Scenario	Before (7.2.0)	After (7.3.0)
Swap 2 players	40 frame updates	2 frame updates
Player joins	40 frame updates	1 frame update
Player leaves	40 frame updates	1 frame update
No changes	40 frame updates	0 frame updates

Technical Implementation:

pfUI.uf.guidTracker tracks GUID per frame
On roster change, compares old GUID vs new GUID
Only sets update_full = true if GUID actually changed
Also forces update_aura = true to refresh buffs/debuffs

🔧 libpredict.lua Optimizations

Eliminated redundant UnitName() calls:

UnitGetIncomingHeals(): Removed double UnitName() call
UnitHasIncomingResurrection(): Removed double UnitName() call
UNIT_HEALTH event handler: Reuses cached name variable

🎯 What's New in Version 7.2.0 (January 24, 2026)

🐱 Druid Secondary Mana Bar Overhaul

Complete rewrite using Nampower's GetUnitField API:

The Druid Mana Bar feature (showing base mana while in shapeshift form) has been completely rewritten to use Nampower's native GetUnitField instead of the deprecated UnitMana() extended return values.

Key Changes:

Component	Before (7.1.0)	After (7.2.0)
Data Source	`UnitMana()` second return value	`GetUnitField(guid, "power1")`
Player Support	✅ Druids only	✅ Druids only
Target Support	❌ Limited/broken	✅ All classes can see Druid mana in all forms
Text Settings	Hardcoded format	Respects Power Bar text config

New Features:

✅ Target Secondary Mana: See enemy/friendly Druid's base mana while they're in Cat/Bear form
✅ Respects Power Text Settings: Uses same format as your Power Bar configuration (powerdyn, power, powerperc, none, etc.)
✅ Available for ALL Classes: Any class can now see Druid mana bars (controlled by "Show Druid Mana Bar" setting)

Technical Implementation:

-- OLD: Extended UnitMana (unreliable for other units)
local _, baseMana = UnitMana("target")  -- Often returns nil for non-player

-- NEW: Direct field access via Nampower
local _, guid = UnitExists("target")
local baseMana = GetUnitField(guid, "power1")      -- Base mana
local baseMaxMana = GetUnitField(guid, "maxPower1") -- Max base mana

🧹 Major Code Cleanup

superwow.lua:

❌ Removed legacy pfDruidMana bar (old SuperWoW-style implementation)
❌ Removed UnitMana() fallback code
✅ Unified all secondary mana bars to use GetUnitField
✅ Fixed text centering issue (was using SetJustifyH("RIGHT"))

nampower.lua - Massive Cleanup:

Removed significant amounts of dead/unused code:

Removed Feature	Reason
Buff tracking system	Data collected but never displayed
HoT Detection (AURA_CAST events)	`OnHotApplied` callback never implemented
Swing Timer (`GetSwingTimers()`)	Never called anywhere in codebase
UNIT_DIED buff/debuff cleanup	Now handled by libdebuff

Result: Cleaner, more maintainable code with reduced memory footprint.

🎯 What's New in Version 7.1.0 (January 24, 2026)

⚡ Cooldown Timer Animation Support

Nameplate Debuff Animations:

✅ Added "Show Timer Animation" option for nameplate debuffs
✅ Uses proper Model frame with CooldownFrameTemplate for Vanilla client
✅ Pie/swipe animation now works on nameplate debuff icons
✅ Configurable via GUI: Nameplates → Show Timer Animation

Target Frame Debuff Animations:

✅ Timer animations now properly visible on target/player frame debuffs
✅ Fixed CD frame scaling and positioning for correct display
✅ SetScale(size/32), SetAllPoints(), SetFrameLevel(14) for proper rendering

cooldown.lua Fix:

✅ Added elseif pfCooldownStyleAnimation == 1 then SetAlpha(1) to make animations visible
✅ Previously animations were created but never shown (alpha stayed 0)

🧹 Memory Leak Fixes

libdebuff.lua:

✅ lastCastRanks table now cleaned up (entries older than 3 seconds removed)
✅ lastFailedSpells table now cleaned up (entries older than 2 seconds removed)
✅ Previously these tables grew indefinitely over long play sessions

unitframes.lua:

✅ Cache cleanup now uses in-place = nil instead of creating new table every 30 seconds
✅ Reduces garbage collector pressure

nameplates.lua:

✅ Reusable debuffSeen table instead of creating local seen = {} on every DEBUFF_UPDATE event
✅ Significant reduction in table allocations during combat

🎯 What's New in Version 7.0.0 (January 21, 2026)

🔥 Complete libdebuff.lua Rewrite (464 → 1594 lines)

Event-Driven Architecture:

Replaced tooltip scanning with a pure event-based system using Nampower/SuperWoW:

OLD (Master):

-- Every UI update:
for slot = 1, 16 do
  scanner:SetUnitDebuff("target", slot)  -- Tooltip scan
  local name = scanner:Line(1)
end

NEW (Experiment):

-- Events fire when changes happen:
RegisterEvent("AURA_CAST_ON_SELF")     -- You cast a debuff
RegisterEvent("DEBUFF_ADDED_OTHER")    -- Debuff lands in slot
RegisterEvent("DEBUFF_REMOVED_OTHER")  -- Debuff removed

-- UI reads from pre-computed tables:
local data = ownDebuffs[guid][spell]  -- Direct lookup

🐱 Combo Point Finisher Support

Dynamic Duration Calculation:

Ability	Formula	Durations (1-5 CP)
Rip	8s + CP × 2s	10s / 12s / 14s / 16s / 18s
Rupture	10s + CP × 2s	12s / 14s / 16s / 18s / 20s
Kidney Shot	2s + CP × 1s	3s / 4s / 5s / 6s / 7s

Before: All Rips showed 18s (wrong for 1-4 CP) After: Shows actual duration based on combo points used

🎭 Carnage Talent Detection

Ferocious Bite Refresh Mechanics:

Tracks Carnage talent (Rank 2) which makes Ferocious Bite refresh Rip & Rake
Only refreshes when Ferocious Bite HITS (not on miss/dodge/parry)
Preserves original duration (doesn't reset to new CP count)
Uses DidSpellFail() API for miss detection

🔄 Additional Features

Debuff Overwrite Pairs: Faerie Fire ↔ Faerie Fire (Feral), Demoralizing Shout ↔ Demoralizing Roar
Slot Shifting Algorithm: Accurate icon placement when debuffs expire
Multi-Caster Tracking: Multiple players' debuffs tracked separately
Rank Protection: Lower rank can't overwrite higher rank timer
Unique Debuff System: Hunter's Mark, Scorpid Sting, etc. handled correctly

📊 Performance Comparison

The Core Difference: Data Access Architecture

Master uses Blizzard API + Tooltip Scanning:

-- Every UnitDebuff call requires tooltip scan
function libdebuff:UnitDebuff(unit, id)
  local texture, stacks, dtype = UnitDebuff(unit, id)
  if texture then
    scanner:SetUnitDebuff(unit, id)  -- Tooltip scan to get spell name
    effect = scanner:Line(1)
  end
  -- Duration comes from hardcoded lookup tables
end

-- UnitOwnDebuff iterates all 16 slots
function libdebuff:UnitOwnDebuff(unit, id)
  for i = 1, 16 do
    local effect = libdebuff:UnitDebuff(unit, i)  -- 16 tooltip scans!
    if caster == "player" then ...
  end
end

Experiment uses Nampower Events + GetUnitField:

-- Single call returns ALL 48 aura slots (32 buffs + 16 debuffs)
local auras = GetUnitField(guid, "aura")  -- Returns array[48] of spell IDs
local stacks = GetUnitField(guid, "auraApplications")  -- Returns array[48] of stack counts

-- Events fire with full data including duration
-- AURA_CAST_ON_OTHER: spellId, casterGuid, targetGuid, effect, effectAuraName, 
--                     effectAmplitude, effectMiscValue, durationMs, auraCapStatus
-- BUFF_REMOVED_OTHER: guid, slot, spellId, stackCount, auraLevel

-- UnitOwnDebuff is just a table lookup
function libdebuff:UnitOwnDebuff(unit, id)
  local _, guid = UnitExists(unit)
  local data = ownDebuffs[guid][spellName]  -- Pre-computed by events
  return data.duration, data.timeleft, ...
end

Nampower Features Used (Experiment Only)

Feature	Purpose	Data Provided
`GetUnitField(guid, "aura")`	Single call returns all 48 aura spell IDs	`array[48]` of spell IDs
`GetUnitField(guid, "auraApplications")`	Stack counts for all auras	`array[48]` of stack counts
`GetUnitField(guid, "power1")`	Base mana for shapeshifted Druids	Mana value (7.2.0)
`GetUnitField(guid, "maxPower1")`	Max base mana	Max mana value (7.2.0)
`AURA_CAST_ON_OTHER`	Instant debuff cast detection	spellId, casterGuid, targetGuid, durationMs
`AURA_CAST_ON_SELF`	Instant self-buff detection	Same as above
`BUFF_REMOVED_OTHER`	Instant aura removal detection	guid, slot, spellId, stackCount
`DEBUFF_ADDED_OTHER`	Debuff slot assignment	guid, slot, spellId, stacks
`DEBUFF_REMOVED_OTHER`	Debuff removal with slot info	guid, slot, spellId

Master uses none of these - it relies on:

UnitDebuff() API (no caster info, no duration)
Tooltip scanning via GameTooltip:SetUnitDebuff() to get spell names
Chat message parsing (CHAT_MSG_SPELL_PERIODIC_*) for duration detection
Hardcoded duration lookup tables

Performance Comparison

Operation	Master	Experiment	Improvement
Initial target scan	16 tooltip scans	1 GetUnitField call (48 slots)	16x fewer calls
Get YOUR debuffs	Loop 16 slots + tooltip each	Direct table lookup	~50-100x faster
Debuff duration	Hardcoded tables / chat parsing	Event provides `durationMs`	Accurate to ms
Detect debuff removal	Polling / timeout	`BUFF_REMOVED_OTHER` event	Instant
Detect new debuff	Chat message delay	`AURA_CAST_ON_OTHER` event	Instant
Caster identification	Not available	Event provides `casterGuid`	New capability
Druid mana (other units)	Not available	`GetUnitField(guid, "power1")`	New in 7.2.0
Memory usage	~50KB	~200KB	4x more (negligible)

Memory Management (7.1.0+ Fixes)

Table	Before 7.1.0	After 7.1.0
`lastCastRanks`	Grew indefinitely	Cleaned every 30s (>3s old)
`lastFailedSpells`	Grew indefinitely	Cleaned every 30s (>2s old)
`debuffSeen` (nameplates)	New table per DEBUFF_UPDATE	Reused single table
`cleanedCache` (unitframes)	New table every 30s	In-place cleanup

What's New in Version 6.2.5 (January 21, 2026)

🎯 Bug report fixes and feature requests.

Fixed aggro indicator on "Player" frame not working properly.
Fixed aggro and combat glow on player frames.
Changed the Aggro indicator timer from 0.1 to 0.2 times per second (5 times per second is enough)
Fixed the 40yard range check not working properly for Shamans and Druids in bear/cat form.
Added 2 new buttons to the Nameplate menu: "Disable Hostile Nameplates in Friendly Zones" and "Disable Friendly Nameplates in Friendly Zones"
changed version to 6.2.5 to push an update for everyone
Feel free to check out https://github.com/me0wg4ming/pfUI/tree/enhanced_release - this is an experiment version with proper tracking for debuffs on current target (use on own risk)

What's New in Version 6.2.3 (January 11, 2026)

🎯 Unit and Raidframes fix (unitframes.lua)

Fixed lag spikes in raids, raid frames should be now butter smooth and cause no lags
Fixed a bug not updating hp/mana and buffs/debuffs properly.
Removed a scan system that scanned always all 40 raid frames 10 times per second (worked out a better solution to track those)
debuff tracking on enemys (for your own abilitys/spells) should be working properly too now

What's New in Version 6.2.2 (January 10, 2026)

🎯 Failed Spell Detection (libdebuff.lua)

✅ Resist/Miss/Dodge/Parry Detection - Spells that fail to land no longer create or update timers
- Detects: Miss, Resist, Dodge, Parry, Evade, Deflect, Reflect, Block, Absorb, Immune
- Timer is either blocked before creation or reverted if fail event arrives late
✅ Public API: libdebuff:DidSpellFail(spell) - Other modules can check if a spell recently failed
- Returns true if spell failed within the last 1 second
- Used by turtle-wow.lua for refresh mechanics

🐱 Druid/Warlock Refresh Fixes (turtle-wow.lua)

✅ Ferocious Bite Refresh Fix - Rip/Rake timers only refresh when Ferocious Bite actually hits
- Previously: Timer refreshed even on dodge/parry/miss
- Now: Uses DidSpellFail() to verify hit before refreshing
✅ Conflagrate Refresh Fix - Immolate duration only reduced when Conflagrate actually hits
✅ Caster Inheritance - Refresh mechanics preserve existing caster info when not explicitly provided

⚡ SuperWoW Compatibility (superwow.lua)

✅ Removed UNIT_CASTEVENT for DoT Timers - SuperWoW's instant event fires before resist/miss detection
- DoT timers now use standard hook-based fallback (compatible with resist detection)
- HoT timers (Rejuvenation, Renew, etc.) still use SuperWoW for instant detection (buffs can't be resisted)

What's New in Version 6.2.1 (January 10, 2026)

🎯 Debuff Timer Protection System (libdebuff.lua)

✅ Spell Rank Tracking - Tracks spell rank for all your DoTs/debuffs
- Uses lastCastRanks table to preserve rank information across multiple event sources
- Fixes race condition where SuperWoW UNIT_CASTEVENT fired before QueueFunction processed pending data
✅ Lower Rank Protection - Lower rank spells cannot overwrite higher rank timers
- Example: If Moonfire Rank 10 is active, casting Rank 5 will be blocked
✅ Other Player Protection - Other players' casts cannot overwrite your debuff timers
- Your DoTs are tracked separately from other players' DoTs
- Multiple players can have their own Moonfire/Corruption on the same target
✅ Shared Debuff Whitelist - Debuffs that are shared by all players update correctly:
- Warrior: Sunder Armor, Demoralizing Shout, Thunder Clap
- Rogue: Expose Armor
- Druid: Faerie Fire, Faerie Fire (Feral)
- Hunter: Hunter's Mark
- Warlock: Curse of Weakness/Recklessness/Elements/Shadow/Tongues/Exhaustion
- Priest: Shadow Weaving
- Mage: Winter's Chill
- Paladin: All Judgements

What's New in Version 6.2.0 (January 10, 2026)

🔮 HoT Timer System (libpredict.lua)

✅ Regrowth Duration Fix - Corrected duration from 21 to 20 seconds (matching actual Turtle WoW spell duration)
✅ GetTime() Synchronization - All timing calls now use pfUI.uf.now or GetTime() for consistent timing across all UI elements
✅ Instant-HoT Detection Fix - Fixed Rejuvenation/Renew not being detected when cast quickly after Regrowth
- Problem: spell_queue was overwritten before processing
- Solution: Instant HoTs now processed immediately at cast hooks with current_cast tracking
✅ SuperWoW UNIT_CASTEVENT Support - Precise Instant-HoT detection using UNIT_CASTEVENT
- Only fires on successful casts (not attempts), eliminating false triggers from GCD/range failures
- Graceful fallback to hook-based detection for players without SuperWoW
✅ HealComm Compatibility - Full compatibility with standalone HealComm addon users
- 0.3s delay compensation for Regrowth messages
- Duplicate detection (0.5s window) prevents double timers
✅ PARTY Channel Support - HoT messages now sent to PARTY channel for 5-man dungeons

🎯 Nameplate Improvements (nameplates.lua)

✅ Target Castbar Zoom Fix - Fixed current target castbar not showing when zoom factor is enabled
- Multi-method target detection: alpha check, istarget flag, and zoomed state
- Proper GUID lookup for target castbar info (was incorrectly using string "target")
✅ Flicker/Vibration Fix - Eliminated nameplate flicker near zoom boundaries
- Alpha check changed from == 1 to >= 0.99 (floating-point fix)
- Zoom tolerance changed from >= w to > w + 0.5 (prevents oscillation)
✅ libdebuff Nil-Checks - Added safety checks to prevent errors when libdebuff data is unavailable

⚡ Spell Queue (nampower.lua)

✅ Error Handling - Added pcall wrapper for GetSpellNameAndRankForId to prevent error spam when spell ID not found

🐱 Druid Improvements

✅ Rip Duration (libdebuff.lua) - Now dynamically calculated based on combo points (10/12/14/16/18 seconds for 1-5 CP)
✅ Ferocious Bite Refresh (turtle-wow.lua) - Now refreshes both Rip AND Rake (previously only Rip), preserving existing duration

⚡ Energy Tick (energytick.lua)

✅ Talent/Buff Energy Filter - Ignores energy gains from talents/buffs (e.g., Ancient Brutality and Tiger's Fury) to prevent tick timer reset from non-natural energy gains

What's New in Version 6.1.1 (January 8, 2026)

🐛 Bugfixes

✅ Chat Level Display Fix - Fixed targeting high-level players overwriting known level with -1. Now shows "??" for unknown levels instead of -1
✅ Nameplate Level Fix - Nameplates now use stored level from database after reload instead of showing "??"
✅ Nameplate Level Color - Level color now correctly uses difficulty color when loaded from database

⚙️ Config Changes

✅ Chat Player Levels - Now disabled by default (was enabled)

What's New in Version 6.1.0 (January 8, 2026)

🐛 Bugfixes

✅ 40-Yard Range Check Fix - Fixed range check not working for raid/party frames due to throttle variable conflict (this.tick vs this.throttleTick)
✅ Aggro Indicator Fix - Fixed aggro indicator not displaying properly on raid/party frames (same throttle issue)
✅ Aggro Detection Cache - Improved aggro cache to only cache positive results, allowing instant detection when aggro changes while maintaining performance
✅ Raid Frames with Group Display - Fixed HP/Mana not updating when "Use Raid Frames to display group members" was enabled without being in a raid
✅ SuperWoW nil-check - Added nil-check for SpellInfo in superwow.lua to prevent errors when SuperWoW is not installed
✅ Missing Event Registration - Added missing events for raid/party frames: PARTY_MEMBER_ENABLE, PARTY_MEMBER_DISABLE, PLAYER_UPDATE_RESTING

🎨 UI Improvements

✅ Share Button Warning - Shows message when Share module is disabled instead of doing nothing
✅ Hoverbind Button Warning - Shows message when Hoverbind module is disabled instead of doing nothing

What's New in Version 6.0.0 (January 5, 2026)

🚀 Major Performance Improvements

✅ Central Raid/Party Event Handler - Replaced per-frame event registration with a centralized system using O(1) unitmap lookups instead of O(n) iteration. Reduces event processing from ~5,760 calls/sec to ~400 calls/sec in 40-man raids (97.5% improvement)
✅ Raid HP/Mana Update Fix - Fixed race condition where unitmap wasn't rebuilt after frame IDs were reassigned, causing HP/Mana bars to not update when players swap positions
✅ OnUpdate Throttling - Added configurable throttles to reduce CPU usage:
- Nameplates: 0.1s throttle (target updates remain instant)
- Tooltip cursor following: 0.1s throttle
- Chat tab mouseover: 0.1s throttle
- Panel alignment: 0.2s throttle
- Autohide hover check: 0.05s throttle
- Libpredict cleanup: 0.1s throttle

🔧 Castbar & Pushback System

✅ Pushback Fix - Fixed spell pushback calculation: now correctly adds delay to casttime instead of start time, matching actual WoW behavior
✅ Player GUID Caching - Caches player GUID on PLAYER_ENTERING_WORLD for efficient self-cast detection
✅ Hybrid Detection System - Uses libcast.db for player casts (handles SPELLCAST_DELAYED events) and SuperWoW's UNIT_CASTEVENT for NPC/other player casts
✅ 2-Decimal Precision - Castbar timer now displays with 2 decimal places (e.g., "1.45 / 2.50") for more precise timing

🐱 Druid Stealth Detection

✅ Event-Based Detection - Replaced polling-based stealth detection with event-driven system using UNIT_CASTEVENT and PLAYER_AURAS_CHANGED
✅ Instant Cat Form Detection - Detects Cat Form via UNIT_CASTEVENT (spell ID 768) for immediate actionbar page switch
✅ Smart Buff Scanning - Only scans buffs when actually needed (entering Cat Form), eliminates 31-buff scan every frame
✅ Cached Variables - Caches stealth state to prevent redundant checks

🎯 Nameplate Improvements

✅ Friendly Player Classification - Fixed friendly players being classified as FRIENDLY_NPC, now correctly uses FRIENDLY_PLAYER for proper nameplate coloring and behavior
✅ Performance Throttle - 0.1s update throttle for non-target nameplates while keeping target nameplate updates instant

FAQ

What does "pfUI" stand for?
The term "pfui!" is german and simply stands for "pooh!", because I'm not a big fan of creating configuration UI's, especially not via the Wow-API (you might have noticed that in ShaguUI).

How can I donate?
You can donate via GitHub or Ko-fi

How do I report a Bug?
Please provide as much information as possible in the Bugtracker. If there is an error message, provide the full content of it. Just telling that "there is an error" won't help any of us. Please consider adding additional information such as: since when did you got the error, does it still happen using a clean configuration, what other addons are loaded and which version you're running. When playing with a non-english client, the language might be relevant too. If possible, explain how people can reproduce the issue.

How can I contribute? Report errors and issues in the Bugtracker. Please make sure to have the latest version installed and check for conflicting addons beforehand.

I have bad performance, what can I do?
Version 6.0.0 includes significant performance optimizations. If you still experience issues:

Disable "Frame Shadows" in Settings → Appearance → Enable Frame Shadows
Check /pfdll to see which DLLs are active (some features require DLLs)
Disable all AddOns but pfUI and enable one-by-one to identify conflicts
Report issues via the Bugtracker

Where is the happiness indicator for pets?
The pet happiness is shown as the color of your pet's frame. Depending on your skin, this can either be the text or the background color of your pet's healthbar:

Green = Happy
Yellow = Content
Red = Unhappy

Since version 4.0.7 there is also an additional icon that can be enabled from the pet unit frame options.

Can I use Clique with pfUI?
This addon already includes support for clickcasting. If you still want to make use of clique, all pfUI's unitframes are already compatible to Clique-TBC. For Vanilla, a pfUI compatible version can be found Here. If you want to keep your current version of Clique, you'll have to apply this Patch.

Where is the Experience Bar?
The experience bar shows up on mouseover and whenever you gain experience, next to left chatframe by default. There's also an option to make it stay visible all the time.

How do I show the Damage- and Threatmeter Dock?
If you enabled the "dock"-feature for your external (third-party) meters such as DPSMate or KTM, then you'll be able to toggle between them and the Right Chat by clicking on the ">" symbol on the bottom-right panel.

Why is my chat always resetting to only 3 lines of text?
This happens if "Simple Chat" is enabled in blizzards interface settings (Advanced Options). Paste the following command into your chat to disable that option: /run SIMPLE_CHAT="0"; pfUI.chat.SetupPositions(); ReloadUI()

How can I enable mouseover cast?
On Vanilla, create a macro with "/pfcast SPELLNAME". If you also want to see the cooldown, You might want to add "/run if nil then CastSpellByName("SPELLNAME") end" on top of the macro.

Everything from scratch?! Are you insane?
Most probably, yes.
