Key fixes include:

Browse Source 
Prevented OS credentials from reaching public hosts or cross-origin redirects.
Preserved Responses API reasoning items across tool rounds.
Fixed nullable tool-call handling and omitted unsupported null request properties.
Propagated cancellation correctly.
Removed tool argument values from logs and tool results from persisted traces.
Added settings validation, clearable optional enums, managed-confidence validation, and safe fallback behavior.
Added tool-definition schema and duplicate validation.
Fixed documentation JSON, changelog regressions, typos, trailing whitespace, and unused Anthropic code.
