Edit me

The 2.2 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.

Modules

If your project has a go.mod file then you can edit the require line to use version v2.2.0, or you can execute the following command inside the directory:

go get fyne.io/fyne/v2@v2.2.0

The next time you build or run your app it will be using the 2.2 release

GOPATH

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 2.2 release.

Fyne command

You should update the fyne tool for v2.2.0 to get the web driver “fyne serve” support. 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.

Changes

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

  • Toolbar item constructors now return concrete types instead of ToolbarItem
  • Low importance buttons no longer draw button color as a background
  • ProgressBar widget height is now consistent with other widgets
