Xslimmer 1.2.1 is a maintenance release that solves a bug detected after launch of version 1.2.0. The bug could cause Xslimmer to remove all localizations of some apps in certain circumstances, rendering those applications unusable. This was the case, for example, for users whose preferred language was British English and decided to keep one language.
Our apologies for not having detected this behaviour even after having conducted a closed beta programme.
Hope you can now enjoy Xslimmer 1.2 to its fullest.
