v2.1.4

Changelog

Workflow History: Support to add workflow history to all or individual steps for a better continuous conversational experience
Google Drive Toolkit: Added the GoogleDriveTools class, to provide your Agents with read and write access to Google Drive.

Update parallel and custom function step events streaming logic in workflows:
- Inspect all events that are yielded during the workflow run, and set the workflow context variables on them before yielding upwards.
- Update parallel step event streaming logic to immediately yield events as they come so that FE can catch and display in real time.
  - Old approach - collect all, yield at end
  - New approach - stream immediately (used queues as we cant yield directly from async running tasks)
Custom events with AG-UI: The AG-UI integration now support custom events. Your Agno custom events will now be delivered in the AG-UI interface in the conventional AG-UI custom event format.
Tool post-hooks in case of tool failure: Our tool post-hooks now also run when the tool run fails. This enables you to easily add logic to run in case of tool failures!

Order of persisted streaming events: Fix a bug where the created_at of some Memory events would be larger than the created_at of the final RunCompleted event.
Handle Team sessions with no runs: When cancelling a Team run early enough, you can end with a session that contains no run objects. Some functionality was failing in this edge case.
Dynamo Table definitions: Fixed a bug where some DynamoDB schemas incorrectly defined non key attributes
Dictionary Key Order Causing Redundant Cache Files: The current caching in agno/tools/function.py used str() to serialize dictionary arguments for cache key generation. Since str() preserves dictionary key order, identical data with different key orders produced different cache keys. Replaced str() with json.dumps(sort_keys=True) to ensure serialization regardless of dictionary key order
Change dimensions type to Optional[int] in FastEmbedEmbedder : Fixed an issue where FastEmbedEmbedder didn’t allow optional dimensions.
