The June 25 release adds autoMode.classifyAllShell to route every Bash and PowerShell command through the auto-mode classifier, surfaces denial reasons in the transcript, and emits a claude_code.assistant_response OTel event carrying the model's actual response text. (Claude Code Docs) The same-week build adds /rewind to resume from before a /clear, makes stopping a background agent permanent so they stop resurrecting, auto-reconnects MCP tools on 401/403, and cuts streaming CPU by ~37%. (Anthropic) I use Claude Code daily in my personal projects, and the permanent-stop fix alone is worth the update. Zombie agents in a long session are maddening.

One Claude Code release fixed two independent permission-check bypasses on the same day. That's the story. Version 2.1.221, shipped August 4, patches a Bash tool bypass where zsh could execute hidden commands embedded inside [[ ]] regex conditionals. The approval prompt never...
If you use plan mode as a read-only sandbox before you approve anything, stop and upgrade first. v2.1.212 patched a real safety hole: in plan mode, file-modifying Bash commands could execute without the permission gate you'd expect. Anything below 2.1.212 could mutate files mi...
Go rotate a key. I'll wait. Claude Code 2.1.246, released August 25, lists this in its changelog: a fix for "telemetry and metrics requests to Anthropic carrying the API key configured for a third-party gateway (ANTHROPIC_BASE_URL); a credential is now only sent to its own hos...
One line in the v2.1.215 changelog, July 19: Claude Code no longer invokes the /verify and /code-review skills on its own. You call them explicitly now (changelog). If your workflow assumed a review pass fired at the end of a task, it doesn't anymore, and nothing told you. Cod...
v2.1.214 added message.uuid, client_request_id, and tool_source attributes to OTel log events, plus CLAUDE_CODE_OTEL_CONTENT_MAX_LENGTH to configure the 60 KB content-attribute truncation (changelog). tool_source is the one to wire up: it distinguishes a built-in tool call fro...
It now dedupes local CLAUDE.md files against checked-in ones, proposes trimming content it can derive from the codebase, ranks unused skills, MCP servers, and plugins by context cost, and flags slow hooks. Background subagents run by default and, when launched from claude agen...
