🚀 Anthropic Official
Claude Code v2.1.212
Ships Jul 17 (00:26 UTC):
/forknow copies conversations into background sessions instead of launching in-session subagents;/subtasktakes over the old/forkbehavior.- Adds
claude auto-mode reset(with confirmation prompt), a session-wide WebSearch call cap (default 200,CLAUDE_CODE_MAX_WEB_SEARCHES_PER_SESSION), and a subagent-spawn cap (default 200,CLAUDE_CODE_MAX_SUBAGENTS_PER_SESSION). - MCP tool calls running over 2 minutes now auto-background themselves;
/resumeopens a picker covering past and deleted sessions. - Fixes plan-mode auto-running, worktree creation, hook infrastructure, SIGTERM handling, Windows Group Policy issues,
/ultrareviewbranch fetching, and prompt-caching behind LLM gateways/custom base URLs.
Claude Code v2.1.210
Ships Jul 14 (23:45 UTC) with a live elapsed-time counter on collapsed tool summaries, a startup warning for Write()/NotebookEdit()/Glob() permission rules, a fix for worktree-isolated subagents running git commands against the main repo, a fix for the ultracode keyword firing on non-human input, and an improved auto-mode permission classifier (now defaults to Sonnet 5 for external sessions).
Claude Agent SDK Python v0.2.121 and TypeScript v0.3.212
Both ship Jul 17 and fix an argv flag-injection bug: --resume/--session-id (Python) and resumeSessionAt/sessionId (TypeScript) now pass as single =-joined tokens so dash-prefixed values can't be parsed as separate CLI flags. The Python SDK also hardens its build scripts against command injection via CLAUDE_CLI_VERSION and bundles Claude CLI 2.1.212; the TypeScript SDK's Agent tool output now reports the resolved model after a mid-turn subagent model swap. Earlier same-window builds (Python v0.2.119, TypeScript v0.3.209/v0.3.210, Jul 14) tracked CLI parity and added timedOutAfterMs to BashToolOutput.
claude-code-action v1.0.176 and v1.0.174
v1.0.174 (Jul 14) redacts GitHub user-to-server (ghu_) tokens in the log sanitizer, a security fix; v1.0.176 (Jul 17) fixes branch-name sanitization, strips alt text from reference-style markdown images, and corrects claude_args model mapping to SDK options.
Claude API — Admin API & docs correction
Jul 14: Admin API adds beta endpoints for Claude Enterprise organization member, group, and custom-role management (anthropic-beta: ce-user-management-2026-07-13).
