 ## .NET runtime

 The .NET 10 runtime has introduced new features and performance improvements, which have been updated for Preview 1. One of the main focuses for .NET 10 is to reduce the abstraction overhead of popular language features. In order to achieve this goal, the JIT's ability to devirtualize method calls has been expanded to cover array interface methods. This means that the JIT can now optimize code that loops over an array, even if there are virtual calls involved. Additionally, the JIT now has the ability to stack-allocate small, fixed-sized arrays of value types that do not contain GC pointers, further reducing the abstraction penalty of reference types.
 
 Another new feature in .NET 10 is the support for Advanced Vector Extensions (AVX) 10.2 for x64-based processors. This is currently disabled by default as hardware supporting AVX10.2 is not yet available. Once it is available, the new intrinsics in the `System.Runtime.Intrinsics.X86.Avx10v2` class can be tested. These updates and improvements are part of the ongoing efforts to achieve performance parity between different implementations in .NET 10.
