Claude Code 2.1.210

2.1.209→2.1.210·July 14, 2026 at 3:12 PM UTC

Patch release: artifact list scopes (including shared), clearer background-command timeout/cwd handling, memory API refresh, and setup-flow polish.

Changelog

  • [new] Artifact list can take scope: mine (default), shared, or all, so you can find artifacts others shared with you as well as your own. Listed rows can be labeled (mine) / (shared) when scope is not only yours.
  • [new] Artifact publish accepts an optional title for the browser tab and gallery name (HTML only; never overrides a <title> in the file). Basename remains the last-resort title.
  • [changed] Backgrounded shell results can report timedOutAfterMs when a command was auto-backgrounded on timeout, and include a cwd hint when a backgrounded command used cd / pushd / popd / chdir — those directory changes do not apply to later commands in the session.
  • [changed] Search/grep-style tool results can include totalLines alongside existing match/file counts.
  • [changed] Memory backend routes moved to /v1/code/memory (plus local credential/mounts helpers). Legacy /api/claude_code/memory and /api/claude_code/team_memory are gone.
  • [changed] Cowork / role setup flow is stricter about tool-first widgets: always ListPlugins before speaking about installed plugins, keep org plugins first in recommendations, never double-show installed items, and treat writing-style / voice-profile setup as a full skill run with clearer yes/no/defer handling.
  • [changed] After opening a PR, Slack “post the PR URL” still only runs when CLAUDE.md mentions it and a Slack send tool is found — failures stay silent.
  • [fix] Worktree stale-lock release is tracked so stuck locks are less likely to block subsequent work.
  • [fix] MCP proxy “needs approval” can retry when approval is still required.

Models & prompts

  • Plan mode still blocks edits and non-readonly tools (plan file excepted); verification sections remain part of solid plan write-ups.
  • Focus mode guidance: when enabled, only the final text of each turn is shown — no mid-turn progress chatter.
  • When a computer-use MCP (mcp__computer-use__*) is available, the agent can screenshot and drive the desktop; tab-close / navigation errors should refresh tab context before continuing.
  • Artifact discovery prompts document the new list scope (and optional limit) for earlier-session published work.
  • Permission-denied and tool-rejection copy distinguishes “stop and wait” vs “try another approach,” including cases where the user supplies a reason.
  • Long-context behavior: partial or full conversation summaries are injected so work can continue without forced early wrap-up; separate prompts cover full-session vs recent-only summaries.
  • Auto-mode classifier rule review and onboarding-guide generation prompts remain available for power-user workflows.

Under the hood

  • New env knobs: CLAUDE_CODE_DISABLE_MEMORY_STREAM_LIST, CLAUDE_CODE_DISABLE_ORG_MEMORY, CLAUDE_CODE_FORCE_WINDOWS_CREDMAN, CLAUDE_CODE_SYNC_SESSION_REFS.
  • Removed env knobs: ANTHROPIC_BEDROCK_MANTLE_API_KEY, CLAUDE_MD_BYTES, CLAUDE_MD_TOKEN_CONTEXT_RATIO.
  • Internal instrumentation for auto-mode setup wizard steps, memory stream list, send-file, plugins/skills manifest sync failures, subagent output flagging, and related experiments.
  • Team-memory sync/cap gates retired in favor of the reorganized memory surface.
  • SDK compatibility list extended through 0.3.209.

Upgrade notes

  • Anything still calling /api/claude_code/memory or /api/claude_code/team_memory must move to the new /v1/code/memory (and related local) routes.
  • If you relied on CLAUDE_MD_BYTES, CLAUDE_MD_TOKEN_CONTEXT_RATIO, or ANTHROPIC_BEDROCK_MANTLE_API_KEY, those are no longer recognized — drop or replace them.
  • Use CLAUDE_CODE_DISABLE_ORG_MEMORY / CLAUDE_CODE_DISABLE_MEMORY_STREAM_LIST only if you need to turn those memory paths off; CLAUDE_CODE_FORCE_WINDOWS_CREDMAN is for Windows credential-store edge cases.
