Upgrading does not change displayed version in AdminCP
 

As the post title says, I've recently run an upgrade on one of my boards from 3.8.2 to 3.8.3. The process goes smoothly, all the install scripts run, at the end of the procedure I'm back in my CP as normal. However, despite having run the procedure a few times now, the version number does not change from 3.8.2 to 3.8.3 in the CP, and I'm still presented with an urgent message to upgrade.

Clearing browser cache, relogging, etc. does not seem to have any effect. Am I missing something here?
