v2.1.122

Summary

Claude Code v2.1.122 ships Bedrock service tier selection (default/flex/priority via env var), PR URL lookup in /resume, and MCP duplicate detection. The fix list covers 12 issues including blank assistant messages, broken /branch forks, image resizing to wrong dimensions, malformed hooks entries crashing the whole settings file, and Vertex AI structured-output failures.

Implications

• Feeds the Claude Code tooling thread: The PR URL resume search is a direct usability improvement for multi-session agentic workflows — operators can hand off context by URL rather than session ID. The hooks settings fix (malformed entry no longer invalidates the whole file) reduces operator footgun surface.
• Bedrock tier selection signals enterprise scale pressure. Adding flex/priority tiers on Bedrock reflects enterprise customers needing predictable throughput SLAs; the infrastructure is now visible as a config knob rather than a hidden platform decision.
