+- Update to version 1.6.6:
+ * Claude Sonnet 5.5 compatibility: server tool calls with absent
+ or malformed args no longer block message serialization, and
+ the Anthropic block translator carries toolset_name through
+ tool call blocks and chunks
+ * Fix docstring examples that don't run as copied
