IntelliJ Plugin v0.488.0 Release Notes

Changes below are new since the last stable IntelliJ plugin, v0.482.3-stable.

Improvements

  • Command hooks supplied by a repository's own `.augment/settings.json` now run only in projects you have marked as trusted. In an untrusted project those hooks are blocked; hooks you configure yourself at the user, system, or plugin level continue to run as before. Changing a project's trust state takes effect on the next hook event, with no restart needed.
  • MCP servers that announce a changed tool list during a session are now picked up automatically. Previously the tool list was read once at startup and could go stale for the rest of the session.
  • MCP servers are now verified with a real round-trip at startup, so a server that completes its handshake but cannot actually service calls no longer shows as connected.
  • Removing an MCP server now sticks. Previously a removed server could reappear when the set of active servers was rebuilt.

Groundwork

  • Included early groundwork for a future guided migration experience. It is not enabled in this release and has no effect today.

Reliability & Performance

  • Chat now recovers quickly when a response stream drops mid-way. Previously an interrupted request could keep spinning until it eventually surfaced a "Request appears to have stalled" message; it now surfaces a retriable failure promptly so you can try again.
  • Your most recent conversations are no longer lost on restart after a long chat history grows past the webview's storage limit. Previously the conversation list could revert to an earlier point.
  • Saving a conversation that times out or fails is now retried automatically instead of being marked saved, and concurrent saves of the same conversation no longer pile up.
  • Long-running MCP tool calls now respect the configured timeout, and a tool result that does not match its declared schema is passed through instead of failing the whole call.
  • Long conversations that cross a summarization boundary no longer fail with a provider error on models that return reasoning content.
  • Chat startup is more tolerant of a slow local connection between the chat panel and the plugin, and retries only the cases that can succeed on a retry.
  • Refreshing a project's source roots now tolerates files that have gone away mid-refresh instead of failing the refresh.

Bug Fixes

  • Fixed the chat panel missing indexing progress and the initial codebase summary when the panel was opened after indexing had already started. The current indexing state is now replayed once the panel is ready, including after a panel reload.
  • Fixed the Context Usage popover overstating how full the context window was by counting MCP tool definitions twice. Tool definitions are now counted once, and the breakdown reconciles with the reported total.
  • Fixed a "Failed to render" error in chat caused by a code block whose language tag was unrecognized. Unknown languages now fall back to plain text.
  • Fixed a "Failed to render" error in chat that could appear for conversations saved by an older version of the plugin.

Compatibility

  • Added support for JetBrains 2026.2 IDEs (build 262). The plugin was previously capped at 2026.1.
  • The plugin now requires JetBrains IDEs 2025.2 (build 252) or newer. It previously installed on 2024.2 and later. If you are on an IDE older than 2025.2, this update is not offered and your currently installed version keeps working; update your IDE to 2025.2 or newer to receive further plugin updates.
