 		[2.14] SEP-1686 tasks (#2378) 
* Implement MCP background tasks (SEP-1686) using Docket

Adds support for background task execution via the MCP task protocol,
powered by Docket for task queue management.

- Tools, resources, and prompts can be marked with `task=True` to run async
- Progress dependency for tracking task progress
- CurrentDocket and CurrentWorker dependencies for advanced use cases
- Client API with `.call_tool(..., task=True)` returns task handles
- Task status notifications via subscriptions
- CLI worker command for distributed task processing

Configuration via environment:
- FASTMCP_ENABLE_DOCKET=true
- FASTMCP_ENABLE_TASKS=true
- FASTMCP_DOCKET_URL=redis://... (or memory:// for single-process)

* Fix tasks example import (TaskStatusResponse → GetTaskResult)

The example was using a non-existent TaskStatusResponse type.
Updated to use mcp.types.GetTaskResult which is what the
on_status_change callback actually receives.

* Fix env var name in Docket error messages

The error messages referenced FASTMCP_EXPERIMENTAL_ENABLE_DOCKET but the
actual setting is FASTMCP_ENABLE_DOCKET.

 		Switch to new OpenAPI parser as default (#2513) 
* Switch to new OpenAPI parser as default

default. The experimental parser (introduced in 2.11) offers better
performance, improved compatibility, and a more maintainable architecture.

- Delete legacy parser (server/openapi.py, utilities/openapi.py)
- Move experimental parser to main locations
- Remove enable_new_openapi_parser feature flag
- Update documentation to remove experimental references

* Add deprecation stubs for experimental OpenAPI imports

* Add deprecated enable_new_openapi_parser setting and deprecation tests

* SDK docs

* REview comments

* Fix docstrings

* Update docstring

* Review comments

 		Fix duplicate keyword argument error in configure_logging (#2381) 
Allow traceback-related kwargs to override defaults by building a dict
with defaults first, then updating with user-provided values.

 		Bump ty to ==0.0.1a25 (#2350) 
* Bump ty to >=0.0.1a25 with type fixes

Follow-up to #2295. Updates ty and fixes compatibility issues with alpha 25, including:

- Updated ignore comment syntax (possibly-unbound-attribute → possibly-missing-attribute)
- Fixed async generator type handling with anext()
- Fixed type narrowing for timeout parameters
- Converted base_url assignments to AnyHttpUrl after string manipulation
- Added CallToolResult to return type annotations
- Removed redundant type casts
- Fixed test form data to use strings instead of bytes

ty alpha 25 has limitations with isinstance() narrowing on unions (see pyproject.toml for details), requiring some targeted type ignores.

* Pin ty to ==0.0.1a25

Alpha releases can have breaking changes, so pin to the tested version.

 		Added to_data_uri method for Image class. (#2227) 
* Added to_data_uri method and path_to_data_uri classmethod for Image class.

* Removed path_to_data_uri classmethod and modified _get_mime_type to use mimetypes.guess_type function instead of hardcoded dictionary.

* Register image/webp with mimetypes before guess_type to support WEBP mimetype detection on Python 3.10.

* Improved branch coverage for Image.to_data_uri.

* Added Image._to_data_uri example in the docs.

 		Add output schema support for OpenAPI tools (#1073) 
* Add output schema support for OpenAPI tools

Implement automatic output schema extraction from OpenAPI responses for
FastMCP tools, addressing issue #1070. Tools generated from OpenAPI specs
now have meaningful output schemas instead of null, improving agent
efficiency when working with structured API responses.

- Add extract_output_schema_from_responses() function to parse response schemas
- Enhance OpenAPITool to accept and use output schemas with proper wrapping
- Automatically wrap non-object responses to comply with MCP requirements
- Include schema definitions and compress unused ones
- Add comprehensive test suite covering object, array, and primitive responses
- Update existing tests to handle structured output with proper typing
- Maintain backward compatibility for specs without response schemas

* Move output schema tests to dedicated test file

Reorganize output schema tests into test_openapi_output_schemas.py to keep
the main test_openapi.py file focused and smaller, as requested. Added two
additional tests for schema definitions handling.

- Move all extract_output_schema_from_responses() tests to new file
- Add tests for schema definitions inclusion
- Remove output schema imports from main test file
