Data binding, storage repositories and animation take Fyne to the next level!

The v2.0.0 release of Fyne marks a big step in the development of the project. It was a chance to step back, see what was working well and what could be improved - and then make the changes in a way that had not been possible whilst maintaining 1.0 compatibility. As a result there are some breaking changes to point the APIs in a better direction for the future. Additionally this means that the import path has now changed to fyne.io/fyne/v2 following the go module convention.

This release also sees the introduction of data binding (that keeps widgets in sync with a data source), storage repositories (allowing developers to connect different types of file stores to our APIs), animation (to give some motion to elements of an application) and a new theme API (that allows more flexible theming of standard components).

The full list of changes follow. Before upgrading an existing project please be sure to read the upgrading doc for information about relevant changes.

Changes that are not backward compatible
