IntelliJ Plugin v0.466.6 Release Notes

New Features

- Added MCP Tool Search with a settings toggle for discovering and summarizing available MCP tools.

- Added IntelliJ support for summarize-and-retry so long conversations can recover and continue automatically.

- Added settings deep links so Augment can open directly to the relevant settings section.

- Added KaTeX math rendering and improved Mermaid diagram styling in chat.

- Built-in commands in Settings are now collapsible and sorted alphabetically.

Conversation Forking

- Editing an earlier message now branches the conversation into a new thread, preserving the original chat history so you can switch between, compare, or continue either version instead of losing the previous one.

Performance and Reliability

- Improved chat reconnection reliability after restarting the IDE or losing the connection mid-response.

- Improved handling of long tool outputs so the full content is available when needed.

- Improved reliability for very large file edits.

- Improved MCP OAuth reliability by preserving refresh tokens and retrying after expired auth.

- Improved MCP setup reliability for servers that require OAuth proxies, custom headers, or scope changes.

- Improved Bitbucket Server repository matching for more URL formats.

- Agent-launched processes no longer steal focus from the IntelliJ Terminal when it is active.
