10 * Changed auto mode for Claude API and Enterprise users, and on Bedrock, Vertex, Foundry and gateways, to default to the server-side classifier, which does not charge for classifier overhead (`CLAUDE_CODE_AUTO_MODE_SERVER=0` opts out on Bedrock, Vertex, Foundry and gateways); warns on billed fallback. See [https://code.claude.com/docs/en/auto-mode-classifier-billing](https://code.claude.com/docs/en/auto-mode-classifier-billing)
11 * Added an `Auto mode server` row to `/status` showing whether this session's auto mode classifier runs on the server

1015 * Added AGENTS.md support: in a project with no CLAUDE.md, Claude Code reads AGENTS.md instead; change it under "Project instructions" in `/config` (not yet on Bedrock, Vertex or Foundry)

18051810 * Fixed plugin install records being silently corrupted when the same plugin is installed in multiple projects
1806 * Fixed recalled or restored paste content occasionally attaching wrong data or silently losing text when the paste had aged out or placeholder numbers collided
1807 * Fixed copy-on-select on Wayland sometimes not reaching the clipboard; the two selection writes no longer race
1808 * Fixed the feedback survey's transcript share silently failing on long sessions; a failed share now shows an error instead of a success message
1809 * Fixed Remote Control auto-start intermittently failing with "Remote credentials fetch failed" on a cold start with a stale login token
1810 * Fixed Remote Control and SDK clients showing a blank "(no content)" message after `/clear` and other output-less commands
