July 2019

This release is our first major version bump. The next release will also be a major version bump, after which we should go back to regularly scheduled minor bumps.

If you're using Blockly plain, with no modifications, you shouldn't notice anything different. If you've made significant changes inside Blockly or are using our more advanced APIs, read on!

In this release (Q2 2019)

• A major cleanup of the Field APIs (huge thanks to Beka Westberg for this work, on both code and documentation)

  • Existing library fields work the same
    • And now we have documentation on all library fields, including code samples
  • Your custom fields may need to be tweaked--see the Upgrading a Custom Field page
  • We have documentation on creating a new custom field!
  • Beka also built a custom field demo with annotated code samples

• Renames of a significant number of utility functions.

  • For a full list of renamed functions, plus bash scripts to do most of the work for you, check out this gist
  • This is part of our push to remove our dependency on the Closure UI library

• Deletion of the accessibility demo

  • We're working on a new approach to accessibility, with a focus on keyboard navigation
  • That is on the keyboard-nav branch, and will be in the Q3 release
  • The old accessibility demo is now in a separate repo, blockly-experimental

• An XSD for validating Blockly XML files

• Assorted bug fixes
