Edit me

The 2.1 release is fully backward compatible with 2.0.4 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 v2.1.0, or you can execute the following command inside the directory:

go get fyne.io/fyne/v2@v2.1.0

The next time you build or run your app it will be using the 2.1 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/v2

Any apps without a module file will now use the 2.1 release.

Fyne command

After a major release of the Fyne toolkit it is advisable to upgrade the fyne commandline tool as well. This will bring new functionality and packaging options, and may be required to deliver certain bug fixes. You can make the upgrade by using the go get command similarly to above:

go get -u fyne.io/fyne/v2/cmd/fyne

After that completes, check you have the new version installed by running fyne version.


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

  • Focusable items are no longer focused automatically on Tap - you need to handle this in a Tapped function, calling: Canvas.Focus(myObj) if it should gain focus
  • Padding in the collection widgets (List, Table, Tree) has been removed, so cells will be the size of the containing widget
  • theme.LightTheme() and DarkTheme() have been deprecated, in preference to theme.DefaultTheme() if you require overriding user choice you can create a custom theme that extends DefaultTheme and in your Color method delegate to the DefaultTheme.Color and pass the variant you require
  • fyne.TextStyle now has a TabWidth field, if you use unnamed struct initialisation this may require changes in your code
