- Added --version-suffix to build and publish
- Support reading DOTNET_* version variables everywhere versions can be read
- Show the commit sha in dotnet --version
- Added tests that check the assembly output version
- Set DOTNET_BUILD_VERSION when producing the CLI app itself so that it has the version information stamped in for help.
- csc kept crashing on stage 2 and it turned out to be a version mismatch with System.Reflection.Metadata.
- Silenced crossgen
- Made omnisharp see all of the projects
