The release candidate for Mu 1.0.0 is out! This is the last step before the final release of Mu 1.0. Apart from a few minor bug fixes, the biggest change from beta 17 is the inclusion of various translations for the user interface. Full details can be found in the changelog.

Many thanks to the following people for their magnificent work on the following translations:

I would love to include more translations in the final release, especially if they’re in one of the following languages:

  • Arabic
  • German
  • Greek
  • Hebrew
  • Hindi
  • Italian
  • Russian

(This list reflects both reach and accessibility of languages so Mu is usable by as many beginner programmers as possible.)

Other highlights include a fix to allow users of Adafruit devices to save a file called This was getting erroneously caught by the new “shadow module” feature which, in this specific case, doesn’t apply. Zander Brown continues to make extraordinary progress in making the user interface both great to look at and consistent across all platforms. We had quite a bit of feedback from teachers who value such UI consistency: it allows them to create resources that apply to all platforms, thus avoiding all the complications of, “if you’re on <platform>, then this will look different” interruptions in the flow of such resources. Finally, Tim Golden and Jonny Austin have done sterling work testing the various fixes for problematic edge-cases in the new BBC micro:bit flash functionality.
