  • New stream transforms let hosts hide, unwrap, or rewrite tool calls for display without affecting agent transcripts
  • cancel() now accepts a timeout so a stuck turn cannot hang the session forever
  • Run tool blocks now show the model's description as the main title when provided
  • Hex color codes in prose now render as colored dots on truecolor terminals
  • New setting "Show thinking blocks" controls whether agent reasoning is visible in the scrollback
  • Spinners now show the description or short command of the task being waited on when available
  • Fixed sessions that remained stuck on the thinking indicator after the model finished responding
  • Mermaid diagrams now correctly display angle brackets and symbols instead of literal HTML entities in labels
  • Recap requests no longer trigger context-length 400 errors on long conversations
  • Grep searches now time out after 20 seconds by default (60s on WSL) instead of always waiting 60s
