v5.20.1

Bugfix

v5.20.0

Features

• add experiments.lazyCompilation.imports to disable lazy compilation of import()s

v5.18.0

Internals

• refactor hashing to move the responsibility of hashing module exports info and referenced modules from Dependencies to the Module
  • Hashing in Dependencies can be much cheaper now (could improve performance when many dependencies are used that point to the same module, like many references to React.createElement)
  • Fixes bugs where Dependencies forgot to hash some details about the referenced module
  • The new model elimiates the potential of such bugs are Dependencies have less responsibilities now
