Download Claude Code 2.1.218

- Changed /code-review to run as a background subagent, so review work no longer fills your conversation and keeps stacked slash commands as its review target
- Added screen-reader announcements of deleted text for word and line deletions (Option+Delete, Ctrl+W, Cmd+Backspace, Ctrl+U, Ctrl+K) in --ax-screen-reader mode
- Fixed Windows paths with \u-prefixed segments (like C:\Users\unicorn) being corrupted into CJK characters in tool inputs, which made those files inaccessible
- Fixed the left arrow key discarding the conversation with no undo: presses right after editing now ask to confirm, and Esc in the agent view returns to the conversation it backgrounded
- Added HTTP status and error text to claude mcp list and /mcp when a server fails to connect, and a warning for MCP config values with hidden leading or trailing whitespace
- Fixed multi-line paste collapsing into one line with j in place of newlines in terminals that encode pasted newlines as Ctrl+J
- Fixed /context reporting stale pre-compact token usage after compacting from the message picker
- Fixed /ultrareview failing on descriptive arguments like "review my auth changes" — they now run a review of your current branch with the text applied as a note to the findings
- Fixed /code-review ultra silently running a local review in non-interactive sessions — it now launches the cloud review
- Fixed gateway spend metering to price Bedrock application-inference-profile ARNs and other config-mapped upstream model IDs at the configured model's rates
- Fixed mojibake when a long IDE selection was truncated mid-emoji, and a case where a tool executor error could be silently dropped
- Fixed an engine teardown race that could start and abandon a phantom turn, and made input pushed after close consistently rejected
- Fixed spurious "[Request interrupted by user]" messages after interrupted tool calls, and an unpaired tool_use block left in the transcript when a tool aborted mid-response
- Fixed VoiceOver reading "new line" instead of echoing the typed space at the end of the input in --ax-screen-reader mode
- Fixed plugin and settings panels not moving the terminal cursor to the focused row, so screen readers and magnifiers can follow arrow-key navigation
- Fixed crashes (maximum call stack exceeded) when a deeply nested watched directory tree was deleted or moved, and when rendering deeply nested UI trees
- Fixed pull request events occasionally being lost when a session exited immediately after creating or linking a PR
- Fixed the Bedrock setup wizard failing profile verification for assume-role profiles in partitioned AWS regions and on proxy-only networks
- Fixed rare negative or incorrect turn duration measurements after a system clock adjustment by timing turns with a monotonic clock
- Fixed the "N MCP servers need authentication" startup notice over-counting claude.ai connectors that aren't connected in claude.ai
- Fixed prompt history entries being dropped or duplicated when history writes raced or failed
- Fixed a retry loop that re-sent identical doomed requests after a context-overflow error with a large thinking budget; Ctrl+B backgrounding now applies the same background-shell caps as other paths
- Fixed agent frontmatter hooks running from untrusted folders: hooks now require the agent file's own folder to have accepted workspace trust
- Fixed fork-session lineage being lost after compaction in headless and SDK sessions
- Fixed a resumed session failing every turn, or crashing on resume, when its history held a malformed delta attachment
- Improved /ultrareview error feedback so Claude can correct an invalid argument instead of retrying it unchanged
- Improved auto mode: the dangerous-rm, background-&, and suspicious-Windows-path checks no longer open permission dialogs; the auto-mode classifier adjudicates them instead
- Improved sandbox command restrictions for IDE interactions
- Improved trust dialogs to name the repository root the grant covers
- Changed /deep-research to start only when invoked manually; Claude no longer launches it on its own
- Changed plan mode with auto to no longer prompt for Bash commands the static analyzer can't prove read-only; the auto-mode classifier judges them instead
- Added an announcement when fast mode changes as a result of switching models via /config model=<x> or Remote Control
- Changed server-managed settings so benign feature and cost toggles no longer trigger the settings-approval prompt
- Changed agent markdown files to reject agent names containing :, which is reserved for plugin namespacing
- Changed skills with context: fork to run in the background by default; opt out per skill with background: false
- Added yes/no/on/off/1/0 (case-insensitive) as accepted values for skill and plugin frontmatter booleans, alongside true/false
- Fixed remote sessions continuing to send heartbeats after their worker was replaced, which left long-lived desktop and IDE processes retrying a rejected request every few seconds forever
