• Upgraded to anthropic>=1. #84
• --no-stream now uses the streaming API under the hood, fixing an SDK error for models with large default max_tokens: "Streaming is required for operations that may take longer than 10 minutes". #85
• Fixed a TypeError when temperature=None was passed explicitly, and fixed a validation bug where setting only top_p incorrectly raised "Only one of temperature and top_p can be set". #70 - thanks Charlie Tonneslan
• -o top_p 0.0 is now sent to the API instead of being treated as unset. #74 - thanks Charlie Tonneslan
• Schemas now use Claude's structured outputs feature for Claude Haiku 4.5. #61
• Claude Opus 4.8 and the Claude 5 family models now support mid-conversation system messages: role: "system" messages passed via messages= are sent inline to the API. #73
• Thinking blocks with omitted content and redacted_thinking blocks are now preserved in conversation history and replayed in tool continuations. #81
