There is a new maintenance release for SketchUp in many languages.  (Release Notes describing what has changed can be found here.)

But before you install the latest, take a moment to open your current version.  Go to Window -> Preferences, then to Shortcuts.  At the bottom click on Export.  Now, it won’t remember everything (like where your buttons are located – but that would be a great feature when upgrading!), but it will keep track of many of your preferences like your keyboard shortcuts.  I have mine to mirror another program so just doing this saves time and headache.
