 		Default fastmcp.Client to mode="auto"; surface extensions=/result_claims= 
Client negotiates the newest mutual protocol era by default (probe
server/discover, fall back to the initialize handshake). ProxyClient and the
inspect utility explicitly pin the handshake era so proxy forwarding and
server_info reads are unchanged. SSE and multi-server config transports are
legacy-only. extensions= and result_claims= (SEP-2133) are thin passthroughs
to the SDK session.

 		perf: reduce PBKDF2 iterations in tests, fix warnings and timeouts (#3504) 
- Use 10 PBKDF2 iterations in test_mode (vs 1M in production) for
  JWT key derivation — cuts auth test setup from ~2.5s to <0.1s
- Add timeout(15) to subprocess-spawning tests (TestKeepAlive,
  test_mcp_config) that exceed 5s under parallel CI load
- Remove pytestmark filterwarnings overrides in tests/deprecated/
  that were leaking DeprecationWarning to test output
- Fix deprecated add_tool_transformation() usage in test_authorization
- Document new settings in settings.mdx

0d513d76b0 Fix test_multi_client_with_logging to filter OpenTelemetry logs 
The test was checking caplog.records length but OpenTelemetry emits
internal warning logs that were getting captured. Filter to only the
test's logger to avoid flaky failures.

 		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.

* Mark flaky Windows test for retry

test_multi_client_transform_with_filtering occasionally times out on Windows CI during exception formatting in linecache.checkcache(). Add @pytest.mark.flaky with 3 retries.

* Remove unnecessary delay from flaky marker
