Released August 8, it fixes a bug where a transient 401 caused Claude Code to replace a long-lived CLAUDE_CODE_OAUTH_TOKEN with a stored login's short-lived token, breaking headless sessions until restart. Also fixes MCP OAuth servers on macOS intermittently failing with a burst of 401s after a keychain read timeout. If you run Claude Code in cron, CI, or an unattended pipeline, upgrade today. These are the exact failure modes that kill an automated run overnight and leave you nothing useful in the logs, and I've lost mornings to less.

I've been telling people for months that the agent code I review is *correct and awful*. Correct in the sense that it compiles, passes the tests, does the thing. Awful in the sense that a 400-line function does the work of 80, the same helper exists three times under different...
The Linux x64 payload is compressed with zstd for both install and auto-update, the binary drops another 2MB by storing bundled skill and prompt text more compactly, code loads on demand rather than staying resident, and the runtime garbage-collects sooner as the heap grows in...
Claude Code 2.1.232 shipped August 13 with a default flipped underneath everyone. Subagent forking is now on: a spawned subagent inherits the full parent conversation and shares its prompt-cache prefix instead of starting cold. Nested spawn depth defaults to 3. Practitioner wr...
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...
The changelog adds a warning before login expiry so background sessions don't die mid-run, a grey pause badge in the footer to confirm you're in manual permission mode, additional working directories now surfaced through MCP roots/list with change notifications, and a fix for...
Per the changelog, Anthropic shipped a Trusted Devices control letting Team/Enterprise admins require device verification before a member can view or steer local Claude Code sessions remotely. v2.1.195 adds CLAUDE_CODE_DISABLE_MOUSE_CLICKS, which kills fullscreen click/drag/ho...
