• Prevent warnings from causing non-zero exit status
• Improve .runtimeconfig.json and generate .deps.json files. Now controllable trhough --generatedeps
• Add Feersum.CompilerServices library
• Cross-targetting support for .NET SDK builds
• Support consuming compiled libraries with re-exported functions.
• Many new Scheme library function implementations (lists, cxr, ..)
