Trojan Killer

What's new in this version:

Runtime:
Improved reliability of the Mono Crash Reporter:
- When Mono crashes it tries to dump a stack trace and other useful info to give developers a way to look into the issue. The crash reporter is now more reliable in certain edge cases

WebAssembly:
- We continue to work on making our WebAssembly support better. Various sets of issues have been resolved in this release and general performance and feature work is happening as well

Community improvements for AIX/PASE and Haiku:
- The ports for these systems received a bunch of improvements from community contributor Calvin Buckley

Class Libraries:
CoreFX integration:
- We continued to replace some of our classes with the implementation from CoreFX to improve performance and compatibility with .NET

Tools:
.NET 4.8 reference assemblies:
- We added reference assemblies for the .NET Framework 4.8 profile. This allows you to build libraries that target .NET 4.8 with MSBuild

- [Mono.Debugger.Soft] Connections are not properly closed
