Have you ever heard something about semantic versioning?

The Elastic.Apm.AspNetCore package is distributed using NuGet. So, the Semantic Versioning 2.0.0 is expected. Why has AspNetCoreErrorDiagnosticsSubscriber (a part of public API) been removed in v1.25.1...v1.25.2 release? Why has PATH version been incremented instead of MAJOR?

We have... but we had to make a pragmatic choice.

This class was only used from an internal class (ApmMiddleWare) and we removed the middleware approach to completely centralise the way we instrument ASP.NET core no matter how our users bootstrap the instrumentation.

We felt the removal of a class that arguably should have been internal to begin with outweighed the need to do a full version bump.

That said we do care deeply about binary compatibility (we even maintain tooling to verify this see: https://github.com/nullean/assembly-differ) and regret this caused an issue for you.
