Edit me

The 1.4 release is fully backward compatible with 1.3.3 and earlier, so upgrading is as simple as updating the version of code you compile with. This is different depending on whether or not you use go modules.


If your project has a go.mod file then you can edit the require line to use version v1.4.0, or you can execute the following command inside the directory:

go get fyne.io/fyne@v1.4.0

The next time you build or run your app it will be using the 1.4 release


If you are not using modules then you will need to update the Fyne checkout in your go source code. To do this execute the following command:

go get -u fyne.io/fyne

Any apps without a module file will now use the 1.4 release.


Although this release is backwards compatible so your code will compile and run as expected, there are some changes which you may notice.

  • The main theme has changed slightly. The blue primary colour is different and users can now choose from a range of primary colors.
  • Buttons are now transparent with an outline by default, this may impact your app design.
  • The Group widget has been deprecated and replaced with the new Card widget.
  • Many container widgets have been deprecated and they have been replaced by new types in the container package.
