anthropics/claude-code v2.1.94

on GitHub

What's changed

• Added support for Amazon Bedrock powered by Mantle, set CLAUDE_CODE_USE_MANTLE=1
• Changed default effort level from medium to high for API-key, Bedrock/Vertex/Foundry, Team, and Enterprise users (control this with /effort)
• Added compact Slacked #channel header with a clickable channel link for Slack MCP send-message tool calls
• Added keep-coding-instructions frontmatter field support for plugin output styles
• Added hookSpecificOutput.sessionTitle to UserPromptSubmit hooks for setting the session title
• Plugin skills declared via "skills": ["./"] now use the skill's frontmatter name for the invocation name instead of the directory basename, giving a stable name across install methods
• Fixed agents appearing stuck after a 429 rate-limit response with a long Retry-After header — the error now surfaces immediately instead of silently waiting
• Fixed Console login on macOS silently failing with "Not logged in" when the login keychain is locked or its password is out of sync — the error is now surfaced and claude doctor diagnoses the fix
• Fixed plugin skill hooks defined in YAML frontmatter being silently ignored
• Fixed plugin hooks failing with "No such file or directory" when CLAUDE_PLUGIN_ROOT was not set
• Fixed ${CLAUDE_PLUGIN_ROOT} resolving to the marketplace source directory instead of the installed cache for local-marketplace plugins on startup
• Fixed scrollback showing the same diff repeated and blank pages in long-running sessions
• Fixed multiline user prompts in the transcript indenting wrapped lines under the ❯ caret instead of under the text
• Fixed Shift+Space inserting the literal word "space" instead of a space character in search inputs
• Fixed hyperlinks opening two browser tabs when clicked inside tmux running in an xterm.js-based terminal (VS Code, Hyper, Tabby)
• Fixed an alt-screen rendering bug where content height changes mid-scroll could leave compounding ghost lines
• Fixed FORCE_HYPERLINK environment variable being ignored when set via settings.json env
• Fixed native terminal cursor not tracking the selected tab in dialogs, so screen readers and magnifiers can follow tab navigation
• Fixed Bedrock invocation of Sonnet 3.5 v2 by using the us. inference profile ID
• Fixed SDK/print mode not preserving the partial assistant response in conversation history when interrupted mid-stream
• Improved --resume to resume sessions from other worktrees of the same repo directly instead of printing a cd command
• Fixed CJK and other multibyte text being corrupted with U+FFFD in stream-json input/output when chunk boundaries split a UTF-8 sequence
• [VSCode] Reduced cold-open subprocess work on starting a session
• [VSCode] Fixed dropdown menus selecting the wrong item when the mouse was over the list while typing or using arrow keys
• [VSCode] Added a warning banner when settings.json files fail to parse, so users know their permission rules are not being applied
