* perf: defer MCP SDK import by fixing import path in agent/core.py
- Change 'from crewai.mcp import MCPServerConfig' to direct path
'from crewai.mcp.config import MCPServerConfig' to avoid triggering
mcp/__init__.py which eagerly loads the full mcp SDK (~300-400ms)
- Move MCPToolResolver import into get_mcp_tools() method body since
it's only used at runtime, not in type annotations
Saves ~200ms on 'import crewai' cold start.
* perf: lazy-load heavy MCP imports in mcp/__init__.py
MCPClient, MCPToolResolver, BaseTransport, and TransportType now use
__getattr__ lazy loading. These pull in the full mcp SDK (~400ms) but
are only needed at runtime when agents actually connect to MCP servers.
Lightweight config and filter types remain eagerly imported.
* perf: lazy-load all event type modules in events/__init__.py
Previously only agent_events were lazy-loaded; all other event type
modules (crew, flow, knowledge, llm, guardrail, logging, mcp, memory,
reasoning, skill, task, tool_usage) were eagerly imported at package
init time. Since events/__init__.py runs whenever ANY crewai.events.*
submodule is accessed, this loaded ~12 Pydantic model modules
unnecessarily.
Now all event types use the same __getattr__ lazy-loading pattern,
with TYPE_CHECKING imports preserved for IDE/type-checker support.
Saves ~550ms on 'import crewai' cold start.
* chore: remove UNKNOWN.egg-info from version control
* fix: add MCPToolResolver to TYPE_CHECKING imports
Fixes F821 (ruff) and name-defined (mypy) from lazy-loading the
MCP import. The type annotation on _mcp_resolver needs the name
available at type-check time.
* fix: bump lxml to >=5.4.0 for GHSA-vfmq-68hx-4jfw
lxml 5.3.2 has a known vulnerability. Bump to 5.4.0+ which
includes the fix (libxml2 2.13.8). The previous <5.4.0 pin
was for etree import issues that have since been resolved.
* fix: bump exclude-newer to 2026-04-22 for lxml 6.1.0 resolution
lxml 6.1.0 (GHSA fix) was released April 17 but the exclude-newer
date was set to April 17, missing it by timestamp. Bump to April 22.
* perf: add import time benchmark script
scripts/benchmark_import_time.py measures import crewai cold start
in fresh subprocesses. Supports --runs, --json (for CI), and
--threshold (fail if median exceeds N seconds).
The companion GitHub Action workflow needs to be pushed separately
(requires workflow scope).
* new action
* Potential fix for pull request finding 'CodeQL / Workflow does not contain permissions'

* feat: add Daytona sandbox tools for enhanced functionality
- Introduced DaytonaBaseTool as a shared base for tools interacting with Daytona sandboxes.
- Added DaytonaExecTool for executing shell commands within a sandbox.
- Implemented DaytonaFileTool for managing files (read, write, delete, etc.) in a sandbox.
- Created DaytonaPythonTool for running Python code in a sandbox environment.
- Updated pyproject.toml to include Daytona as a dependency.
* chore: update tool specifications
* refactor: enhance error handling and logging in Daytona tools
- Added logging for best-effort cleanup failures in DaytonaBaseTool and DaytonaFileTool to aid in debugging.
- Improved error message for ImportError in DaytonaPythonTool to provide clearer guidance on SDK compatibility issues.

* refactor: remove CodeInterpreterTool and deprecate code execution params
CodeInterpreterTool has been removed. The allow_code_execution and
code_execution_mode parameters on Agent are deprecated and will be
removed in v2.0. Use dedicated sandbox services (E2B, Modal, etc.)
for code execution needs.
Changes:
- Remove CodeInterpreterTool from crewai-tools (tool, Dockerfile, tests, imports)
- Remove docker dependency from crewai-tools
- Deprecate allow_code_execution and code_execution_mode on Agent
- get_code_execution_tools() returns empty list with deprecation warning
- _validate_docker_installation() is a no-op with deprecation warning
- Bedrock CodeInterpreter (AWS hosted) and OpenAI code_interpreter are NOT affected
* fix: remove empty code_interpreter imports and unused stdlib imports
- Remove empty `from code_interpreter_tool import ()` blocks in both
crewai_tools/__init__.py and tools/__init__.py that caused SyntaxError
after CodeInterpreterTool was removed
- Remove unused `shutil` and `subprocess` imports from agent/core.py
left over from the code execution params deprecation

* fix: remove redundant _validate_docker_installation call and fix list type annotation
- Drop the _validate_docker_installation() call inside the allow_code_execution
block — it fired a second DeprecationWarning identical to the one emitted
just above it, making the warning fire twice.
- Annotate get_code_execution_tools() return type as list[Any] to satisfy mypy
(bare `list` fails the type-arg check introduced by this branch).

* ci: retrigger
* fix: update test_crew.py to remove CodeInterpreterTool references
CodeInterpreterTool was removed from crewai_tools. Update tests to
reflect that get_code_execution_tools() now returns an empty list.

* chore: update uv.lock with new dependency groups and versioning adjustments
- Added a new revision number and updated resolution markers for Python version compatibility.
- Introduced a 'dev' dependency group with specific versions for various development tools.
- Updated sdist and wheels entries to include upload timestamps for better tracking.
- Adjusted numpy dependencies to specify versions based on Python version markers.
* feat: bump versions to 1.14.0a1
* 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.
