Null safety

• Null safety support
• Performance optimizations for all commands

Semiautomatic pubspec.lock correction

• Feature: Semiautomatic correction of pubspec.lock inconsistencies with probe --correct
• Kudos to @RtgrV for design and implementation!

Bootstrapping performance improvement

• Optimization: Much faster dependency analysis for incremental bootstrapping
• Kudos to @werediver and @spkersten for finding and fixing it!

Deps

• Feature: "borg deps" lists external dependencies for multiple packages across repository
• Improvement: Packages without pubspec.lock are always bootstrapped in all modes

Dart 2.12+ expects SDK specification in pubspec.yaml

1.4.6

Release 1.4.6 preps

Dart 2.10 and upgraded dependencies

1.4.5+1

1.4.5+1 release preps

Incremental bootstrapping by default

• Feature: Incremental bootstrapping is the default bootstrapping mode
• Optimization: Massive improvement of performance of dependency analysis during incremental bootstrapping
• Bugfix: Incremental bootstrapping ignores deleted packages

Production-grade incremental bootstrapping

• Bootstrapping dependency analysis takes dependency overrides into account
• Unit test coverage improvements

Incremental bootstrapping 3

• Improved performance of incremental bootstrapping for massive changes of packages configuration

Maturing of incremental bootstrapping implementation

• Correct handling of rolled back changes of pubspec files
• Incremental bootstrapping is ignored when Dart version is changed between runs of borg boot
• Incremental bootstrapping is ignored when Flutter SDK version is changed between runs of borg boot
• Incremental bootstrapping is ignored when command line specifies packages to bootstrap
• Incremental bootstrapping ignores previous bootstrapping of specific (not all) packages
• Boot mode switch is persistent
