## What's changed
- Added `ANTHROPIC_BEDROCK_SERVICE_TIER` environment variable to select a Bedrock service tier (`default`, `flex`, or `priority`), sent as the `X-Amzn-Bedrock-Service-Tier` header
- Pasting a PR URL into the `/resume` search box now finds the session that created that PR (GitHub, GitHub Enterprise, GitLab, and Bitbucket)
- `/mcp` now shows claude.ai connectors hidden by a manually-added server with the same URL, with a hint to remove the duplicate
- Clarified the `/mcp` message shown when an MCP server is still unauthorized after the browser sign-in flow
- OpenTelemetry: numeric attributes on `api_request`/`api_error` log events are now emitted as numbers, not strings
- OpenTelemetry: added `claude_code.at_mention` log event for `@`-mention resolution
- Fixed `/branch` producing forks that fail with "tool_use ids were found without tool_result blocks" when the source session contained entries from rewound timelines
- Fixed `/model` not showing the Effort option for Bedrock application inference profile ARNs, and those ARNs not receiving `output_config.effort`
- Fixed Vertex AI / Bedrock returning `invalid_request_error: output_config: Extra inputs are not permitted` on session-title generation and other structured-output queries
- Fixed Vertex AI `count_tokens` endpoint returning 400 errors for users behind proxy gateways
- Fixed `spinnerTipsOverride.excludeDefault` not suppressing the time-based spinner tips
- Fixed ToolSearch missing MCP tools that connected after session start in nonblocking mode
- Fixed `!exit` / `!quit` in bash mode terminating the CLI instead of running as a shell command
- Fixed images sent to newer models being resized to 2576px per side instead of the correct 2000px maximum
- Fixed remote control session idle status redrawing twice per second, which could flood `tmux -CC` control pipes and pause the terminal
- Fixed assistant messages appearing blank in some sessions due to a stale view preference
- Fixed a malformed hooks entry in `settings.json` no longer invalidating the entire file
- Voice mode: keybindings bound to Caps Lock now show an error since terminals don't deliver Caps Lock as a key event
