v0.65.2

No release notes provided.

v0.65.1

Fixed

• Fixed bash output truncation by line count to always persist full output to a temp file, preventing data loss when output exceeds 2000 lines but stays under the byte threshold (#2852)
• RpcClient now forwards subprocess stderr to parent process in real-time (#2805)
• Theme file watcher now handles async fs.watch error events instead of crashing the process (#2791)
• Fixed stored session cwd handling so resuming or importing a session whose original working directory no longer exists now prompts interactive users to continue in the current cwd, while non-interactive modes fail with a clear error.
• Fixed resource collision precedence so project and user skills, prompt templates, and themes override package resources consistently, and CLI-provided paths take precedence over discovered resources (#2781)
• Fixed OpenAI-compatible completions streaming usage accounting to preserve prompt_tokens_details.cache_write_tokens and normalize OpenRouter cached_tokens, preventing incorrect cache read/write token and cost reporting in pi (#2802)
• Fixed CLI extension paths like git:gist.github.com/... being incorrectly resolved against cwd instead of being passed through to the package manager (#2845 by @​aliou)
• Fixed piped stdin runs with --mode json to preserve JSONL output instead of falling back to plain text (#2848 by @​aliou)
• Fixed interactive command docs to stop listing removed /exit as a supported quit command (#2850)

v0.65.0

New Features

• Session runtime API: createAgentSessionRuntime() and AgentSessionRuntime provide a closure-based runtime that recreates cwd-bound services and session config on every session switch. Startup, /new, /resume, /fork, and import all use the same creation path. See https://github.com/badlogic/pi-mono/tree/HEAD/packages/coding-agent/blob/HEAD/docs/sdk.md and https://github.com/badlogic/pi-mono/tree/HEAD/packages/coding-agent/blob/HEAD/examples/sdk/13-session-runtime.ts.
• Label timestamps in /tree: Toggle timestamps on tree entries with Shift+T, with smart date formatting and timestamp preservation through branching (#2691 by @​w-winter)
• defineTool() helper: Create standalone custom tool definitions with full TypeScript parameter type inference, no manual casts needed (#2746). See https://github.com/badlogic/pi-mono/tree/HEAD/packages/coding-agent/blob/HEAD/docs/extensions.md.
• Unified diagnostics: Arg parsing, service creation, session option resolution, and resource loading all return structured diagnostics (info/warning/error) instead of logging or exiting. The app layer decides presentation and exit behavior.

Breaking Changes

• Removed extension post-transition events session_switch and session_fork. Use session_start with event.reason ("startup" | "reload" | "new" | "resume" | "fork"). For "new", "resume", and "fork", session_start includes previousSessionFile.
• Removed session-replacement methods from AgentSession. Use AgentSessionRuntime for newSession(), switchSession(), fork(), and importFromJsonl(). Cross-cwd session replacement rebuilds all cwd-bound runtime state and replaces the live AgentSession instance.
• Removed session_directory from extension and settings APIs.
• Unknown single-dash CLI flags (e.g. -s) now produce an error instead of being silently ignored.

Migration: Extensions

Before:

pi.on("session_switch", async (event, ctx) => { ... });
pi.on("session_fork", async (_event, ctx) => { ... });

After:

pi.on("session_start", async (event, ctx) => {
  // event.reason: "startup" | "reload" | "new" | "resume" | "fork"
  // event.previousSessionFile: set for "new", "resume", "fork"
});
