New features

  • The preprocessor SYS variable BUILDARCH replaces PLATFORM to clarify that it’s the platform the package is being compiled for, not the platform the build is running on.
  • Transforms can now contain tables with added columns.
  • Table definitions are now consistent with MSI 4.5 beta 2.

Bug fixes

  • Command-line argument processing has been tightened up and now all tools print warnings for all invalid arguments.
  • Various updates in Dark to improve decompiling invalid packages.
