The v2.1.0 release represents a huge step forward since 2.0 - just as many commits as went into the v2.0.0 release!
We added new widgets, a Lifecycle API, storage helpers, build metadata and lots of optimisations too.
Check out the full release below and let us know what you think :)

Note that custom focusable widgets will not automatically be focussed on tap any more, you may wish to update your code so it requests focus on tapped (see https://developer.fyne.io/api/v2.1/upgrading).
