* refactor(memory): convert Memory, MemoryScope, and MemorySlice to BaseModel
* fix(test): update mock memory attribute from _read_only to read_only
* fix: handle re-validation in wrap validators and patch BaseModel class in tests
ThreadPoolExecutor threads do not inherit the calling thread's contextvars
context, causing _event_id_stack and _current_celery_task_id to be empty
in worker threads. This broke OTel span parenting for parallel tool calls
(missing parent_event_id) and lost the Celery task ID in the enterprise
tracking layer ([Task ID: no-task]).
Fix by capturing an independent context copy per submission via
contextvars.copy_context().run in CrewAgentExecutor._handle_native_tool_calls,
so each worker thread starts with the correct inherited context without
sharing mutable state across threads.
* feat: enhance memory recall limits and update documentation
- Increased the memory recall limit in the Agent class from 5 to 15.
- Updated the RecallMemoryTool to allow a recall limit of 20.
- Expanded the documentation for the recall_memory feature to emphasize the importance of multiple queries for comprehensive results.
* feat: increase memory recall limit and enhance memory context documentation
- Increased the memory recall limit in the Agent class from 15 to 20.
- Updated the memory context message to clarify the nature of the memories presented and the importance of using the Search memory tool for comprehensive results.
* refactor: remove inferred_categories from RecallState and update category merging logic
- Removed the inferred_categories field from RecallState to simplify state management.
- Updated the _merged_categories method to only merge caller-supplied categories, enhancing clarity in category handling.
* refactor: simplify category handling in RecallFlow
- Updated the _merged_categories method to return only caller-supplied categories, removing the previous merging logic for inferred categories. This change enhances clarity and maintains consistency in category management.
* fix(gemini): group parallel function_response parts in a single Content object
When Gemini makes N parallel tool calls, the API requires all N function_response parts in one Content object. Previously each tool result created a separate Content, causing 400 INVALID_ARGUMENT errors. Merge consecutive function_response parts into the existing Content instead of appending new ones.
* Address change requested
- function_response is a declared field on the types.Part Pydantic model so hasattr can be replaced with p.function_response is not None
* fix(telemetry): skip signal handler registration in non-main threads
When CrewAI is initialized from a non-main thread (e.g. Streamlit, Flask,
Django, Jupyter), the telemetry module attempted to register signal handlers
which only work in the main thread. This caused multiple noisy ValueError
tracebacks to be printed to stderr, confusing users even though the errors
were caught and non-fatal.
Check `threading.current_thread() is not threading.main_thread()` before
attempting signal registration, and skip silently with a debug-level log
message instead of printing full tracebacks.
Fixes crewAIInc/crewAI#4289
* fix(test): move Telemetry() inside signal.signal mock context
Refs: #4649
* fix(telemetry): move signal.signal mock inside thread to wrap Telemetry() construction
The patch context now activates inside init_in_thread so the mock
is guaranteed to be active before and during Telemetry.__init__,
addressing the Copilot review feedback.
Refs: #4289
* fix(test): mock logger.debug instead of capsys for deterministic assertion
Replace signal.signal-only mock with combined logger + signal mock.
Assert logger.debug was called with the skip message and signal.signal
was never invoked from the non-main thread.
Refs: #4289
pypdf <6.7.4 has multiple DoS vulnerabilities via crafted PDF streams
(FlateDecode, LZWDecode, RunLengthDecode, XFA, TreeObject, outlines).
Only basic PdfReader/PdfWriter APIs are used in crewai-files, none of
which changed in the 5.0 or 6.0 breaking releases.
* refactor: update step callback methods to support asynchronous invocation
- Replaced synchronous step callback invocations with asynchronous counterparts in the CrewAgentExecutor class.
- Introduced a new async method _ainvoke_step_callback to handle step callbacks in an async context, improving responsiveness and performance in asynchronous workflows.
* chore: bump version to 1.10.1b1 across multiple files
- Updated version strings from 1.10.1b to 1.10.1b1 in various project files including pyproject.toml and __init__.py files.
- Adjusted dependency specifications to reflect the new version in relevant templates and modules.
- Introduced lazy imports for the Memory and EncodingFlow classes to optimize import time and reduce initial load, particularly beneficial for deployment scenarios like Celery pre-fork.
- Updated the Memory class to include new configuration options for aggregation queries, enhancing its functionality.
- Adjusted the __getattr__ method in both the crewai and memory modules to support lazy loading of specified attributes.
* chore(deps): update lancedb version and add lance-namespace packages
- Updated lancedb dependency version from 0.4.0 to 0.29.2 in multiple files.
- Added new packages: lance-namespace and lance-namespace-urllib3-client with version 0.5.2, including their dependencies and installation details.
- Enhanced MemoryTUI to display a limit on entries and improved the LanceDBStorage class with automatic background compaction and index creation for better performance.
* linter
* refactor: update memory recall limit and formatting in Agent class
- Reduced the memory recall limit from 10 to 5 in multiple locations within the Agent class.
- Updated the memory formatting to use a new `format` method in the MemoryMatch class for improved readability and metadata inclusion.
* refactor: enhance memory handling with read-only support
- Updated memory-related classes and methods to support read-only functionality, allowing for silent no-ops when attempting to remember data in read-only mode.
- Modified the LiteAgent and CrewAgentExecutorMixin classes to check for read-only status before saving memories.
- Adjusted MemorySlice and Memory classes to reflect changes in behavior when read-only is enabled.
- Updated tests to verify that memory operations behave correctly under read-only conditions.
* test: set mock memory to read-write in unit tests
- Updated unit tests in test_unified_memory.py to set mock_memory._read_only to False, ensuring that memory operations can be tested in a writable state.
* fix test
* fix: preserve falsy metadata values and fix remember() return type

* fix: preserve null types in tool parameter schemas for LLM
Tool parameter schemas were stripping null from optional fields via
generate_model_description, forcing the LLM to provide non-null values
for fields.
Adds strip_null_types parameter to generate_model_description and passes False when generating tool
schemas, so optional fields keep anyOf: [{type: T}, {type: null}]
