Packages Published

ag-ui-crewai@0.3.1

• RunAgentInput.context is now retained on CopilotKitState; previously Pydantic discarded it before @start ran.
• Endpoint helpers now forward FastAPI route kwargs (name, tags, summary, operation_id, dependencies, include_in_schema).
• Conversational runs whose stream carries no translatable frames now terminate with a proper terminal event instead of an empty HTTP 200.
• Abandoned conversational Flow workers are now bounded and contained after client disconnect, timeout, or cancellation.
• OpenAI Responses handling simplified to use the public aresponses entrypoint; fixes output_item.done.
• pydantic (v2, <3) is now a declared direct dependency.
• Ctrl-C now stops the dojo server instead of requiring SIGKILL.
• Dojo app is now built once per boot in the serving process.
• Removed the dead, fully commented-out enterprise.py module from published artifacts.
• Published distributions now include a Changelog URL in metadata.
• The dev console script is no longer published; run the dojo via the relocated examples project instead.
• The dojo server and demo flows moved into a separate examples project and are no longer shipped in the published package.
• enterprise.py removed from the package.

TypeScript (npm) - published at 16:23:30 UTC

@ag-ui/mastra@1.1.4

• Server tools can now show a live "running" step via opt-in MastraAgentConf live TOOL_CALL_START emission.
• Resumed runs now receive the frontend tools of the run they continue, so frontend-only agents no longer end with no output.
• Mastra tripwire chunks now surface their reason as assistant text instead of ending the run silently; terminal retry reasons are preserved.
• Developer messages are now forwarded (mapped to user role) instead of being dropped.
• Thread-scoped working memory is now seeded on a new thread, preventing "Thread not found" errors on the first turn.
• Resume now emits TOOL_CALL start/args/end before the result and preserves streamed tool arguments.
• Replay conversion recovers from malformed or concatenated tool-call argument strings instead of failing all later runs.
• Results paired with skipped replay calls are now dropped; suppressed spurious warning on brand-new threads.
