3.0.87 Jan 2026
Release notes
Patch Changes
- bee4f82: fix(anthropic): enable structured output support for claude-haiku-4-5
  
  This fixes an issue where the strict: true property was not included in the request body when using tools with Claude Haiku 4.5, because supportsStructuredOutput was incorrectly set to false for this model.
  
  Claude Haiku 4.5 supports structured outputs, so the strict property should be forwarded to the Anthropic API when specified on tools.

3.0.65 Jan 2026
Release notes
Patch Changes
- 2231e84: fix(anthropic): implement temperature/topP mutual exclusivity
  
  Resolves the Anthropic API breaking change where sampling parameters must use only temperature OR top_p, not both. When both parameters are provided:
  - Temperature takes priority and topP is ignored
  - A warning is added to inform users: "topP is not supported when temperature is set. topP is ignored."
  - The validation only runs when thinking mode is not enabled (thinking mode has its own parameter validation)
