redux v4.0.0-beta.1 Release Notes

Release Date: 2017-11-16 // over 3 years ago
  • ๐Ÿฑ It's time to bump the major version on Redux! ๐ŸŽ‰

    ๐Ÿš€ This is the first beta release of 4.0.0. Despite the version bump, the changes are relatively minor. Most of it was covered in the 4.0 tracking issue: #1342.

    The largest amount of work was done with our Typescript definitions. They have been completely overhauled, so they should work better and take advantage of all the new stuff in TS 2.x.

    ๐Ÿ— The other big change is we are now bundling our CommonJS and ES builds like React has done recently. This means direct, private imports (import createStore from 'redux/lib/createStore') will no longer work. This ensures our modules are maintaining a consistent contract with your apps and that any reorganization we choose to do internally has no effect on your usage of Redux.

    ๐Ÿš€ We've also tightened up some behavior quirks and dropped support for IE < 11. The vast majority of apps should require no changes. But we will run through a standard RC process to gradually release this out to the world and ensure no big headaches for everyone during the holiday season.
