 * Fix signature generation: SRTP constraints use postfix syntax that fails conformance, now uses explicit type param declarations. ([Issue #19594](https://github.com/dotnet/fsharp/issues/19594), [PR #19609](https://github.com/dotnet/fsharp/pull/19609))
 * Fix signature generation: type params with special characters missing backtick escaping. ([Issue #19595](https://github.com/dotnet/fsharp/issues/19595), [PR #19609](https://github.com/dotnet/fsharp/pull/19609))
 * Fix internal error when using custom attribute with `[<Optional>]` value type parameter and no `[<DefaultParameterValue>]`. ([Issue #8353](https://github.com/dotnet/fsharp/issues/8353), [PR #19484](https://github.com/dotnet/fsharp/pull/19484))
+* Fix overload resolution of static member extension if one or more intrinsics candidates exist ([Issue #19664](https://github.com/dotnet/fsharp/issues/19664), [PR #19698](https://github.com/dotnet/fsharp/pull/19698))
