Mill 0.11.0 is a breaking release with a focus on polish. This release fixes many long-standing sharp edges that could not be fixed without breaking backwards compatibility, and cleans up the Mill codebase for better maintainability and so we can offer better compatibility guarantees going forward. User-facing improvements include an overhauled documentation-site, much easier cross builds, faster/more-robust bootstrapping, better error messages. It aims to do everything Mill already does, but better.
