Version 4.38.1 changes some of the font names. This was necessary for Java applications to be able to correctly use the italic font face (without this change, I could not get Netbeans to use the italic font). Since the font family was not changed (it still is “Terminus (TTF)”), you should not need to change your configurations.
As always, you can get the latest Terminus TTF version from http://files.ax86.net/terminus-ttf (now with a new homepage!).
