Changelog

New Features:

Unsplash image search tools: Added UnsplashTools toolkit for searching and retrieving high-quality, royalty-free images from Unsplash API.
Moonshot model provider: Added moonshot.ai model provider
external_execution_silent param for tool decorator: Added a new param to make external tool execution silent by not populating the run response content with placeholder strings

dependencies in Workflows: When using JWTMiddleware with dependencies_claims to inject user data from JWT tokens, the dependencies were correctly available to agent tools when calling the agent directly via /agents/{agent_id}/runs, but not when the same agent ran as part of a workflow via /workflows/{workflow_id}/runs.

Markdown Chunker - split_on_headings now respects chunk_size parameter.
LanceDB empty vectors - Added a fix to reduce empty vectors in lancedb due to embedding failures
SurrealDB - created_at timestamps are now preserved on updates and get_session correctly filters by session type
Firestore - Fixed a bug causing rename session operation to lead to unintended overwrites
