 **New Features:**
 
+* **Agent Knowledge Base:** View and edit the files that inform how Promptless writes documentation—your style guide, product overview, and documentation guidelines. Find them in Settings under the Agent Knowledge Base tab. Promptless updates these files automatically as it learns from your feedback, but you can also edit them directly.
+
 * **Atlassian Integration (Jira + Confluence):** Connect both Jira and Confluence through a single unified Atlassian integration. Promptless now searches your Confluence spaces alongside Jira tickets—pulling documentation patterns, terminology, and architectural decisions when creating suggestions. This replaces the previous Jira-only integration—if you previously connected Jira, reconnect to access Confluence while preserving your Jira project configuration.

+* **Guided Onboarding Wizard:** A 6-step wizard walks new users through Promptless setup: connecting Slack, connecting your documentation platform, configuring triggers, adding context sources, setting agent preferences, and starting your trial. Progress saves automatically—leave and return to pick up where you left off. Team members from the same organization can continue setup without losing previous progress.
+
+* **Automatic Support Channel:** Installing the Promptless Slack app automatically creates a shared Slack Connect channel and sends you an invitation. Accept to get a direct line to the Promptless team for questions and support—no setup required.
+
+* **Self-Service Signup:** Sign up for Promptless at [accounts.gopromptless.ai](https://accounts.gopromptless.ai)—no sales call required.

 **Improvements:**
 
 * **Upgraded to Claude Opus 4.5:** Documentation suggestions now use Claude Opus 4.5 for improved reasoning, analysis, and documentation context understanding.

 * **Screenshot Cropping:** Promptless can now crop screenshots to focus on specific UI elements—highlighting exactly what users need to see without extra clutter.
 * **Automatic Suggestion Updates from Main:** When changes are pushed to your documentation's main branch, Promptless merges those updates into all open suggestion branches and automatically resolves any conflicts.
 * **Trigger Source Filter:** Filter suggestions on the Change History page by how they were triggered—Slack messages, Web UI requests, or GitHub PRs. For GitHub, expand the dropdown to filter by specific repositories.
+* **Estimated Review Time:** Suggestions now display an estimated review time based on lines changed. Sort by "Shortest review" to prioritize quick reviews—useful for clearing small updates first or ramping up new team members.
+* **GitHub Repository Help Link:** During onboarding, if you uncheck "Trigger on all repos" and don't see the repositories you need, a help link now points to documentation on adding more repositories to your GitHub App.
+* **Slack Installation Pending Flow:** If you don't have admin permissions to install Slack apps, an "Installation Pending" screen shows clear next steps—contact your admin, continue setup without Slack, or try again after approval.

 * **Suggestion Stability for Revert PRs:** Fixed an issue where suggestions could be incorrectly deleted when processing PRs that revert previously documented changes—suggestions now remain active and continue receiving updates correctly.
 * **PR Replay Status Accuracy:** Fixed PR replays to show the correct PR status on the Triggers page. Previously, replayed PRs always showed "open" status regardless of whether the PR was actually merged, closed, or in draft state.
 * **GitHub Trigger Icons:** Fixed the Change History page to show the GitHub icon for all GitHub-based triggers—including GitHub Enterprise PRs, merged PRs, and GitHub Issues. Previously, the icon only appeared for regular open PRs.
+* **GitHub PR Event Filtering:** Fixed an issue where Promptless could trigger on PR events like `edited` or `synchronize` instead of only triggering when PRs are opened, marked ready for review, or reopened.
+* **Large Image Processing:** Fixed failures when processing triggers with large images. Promptless now automatically compresses images that exceed size limits, so you can include high-resolution screenshots and images in Slack messages, GitHub issues, or other triggers without issues.
+* **Documentation PR Update Reliability:** Fixed intermittent failures when updating documentation PRs with new changes. Promptless now handles transient GitHub API timing issues more gracefully, ensuring suggestions are consistently applied to your docs PRs.
+* **Onboarding Integration Setup:** Fixed an issue where connecting integrations (like Slack or GitHub) during onboarding could fail due to blocked OAuth callback URLs.
+* **Onboarding Wizard Progress:** Fixed an issue where progress wasn't saved when returning to the onboarding wizard immediately after connecting Slack.
+* **Onboarding Trigger Dropdowns:** Fixed the trigger configuration step to show your actual repositories and Slack channels in the selection dropdowns. Previously, the dropdowns displayed placeholder data instead of your connected integrations.
+* **Onboarding Agent Preferences:** Fixed an issue where agent preferences configured during onboarding weren't being saved—agent behavior and beta feature selections now persist correctly.
+* **Onboarding Pipeline Creation:** Fixed 500 errors that could occur when completing the onboarding wizard's context sources step.
+* **Onboarding Wizard Visual Smoothness:** Fixed visual flickering in the onboarding wizard during OAuth callbacks—the wizard now shows a loading spinner instead of briefly flashing incorrect content.
+* **Slack Connect Channel Visibility:** Fixed an issue where Slack Connect support channels were created as private in your workspace—support channels now appear as public, so you can invite other team members from your organization.
