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
