Final version released, topic locked:
This is just a minor GIMP update, but it's using the new installer script that calculates free space accurately and this is the first app with options (you can choose whether or not it uses translations) to do so, so I wanted to have folks give it a quick test before releasing.
In particular, try it out doing upgrades on nearly full drives that may be able to handle it with or without the translations included.
