Other improvements include a small fix for the episode list filter button for locales where the text sometimes became longer than the button:
As you can see, in the left screenshot (gPodder 3.1.1) the "Hide deleted" text (in German: "Gelöschte verstecken") goes over the toolbar button. To "fix" this, the toolbar button has been made wider (right screenshot, gPodder 3.1.2), which (in my opinion) also looks a bit nicer.
The rest of the improvements include some fixes to the CLI, updated and added translations, and some minor build system fixes - read the full changelog if you want the gory details :)
The MeeGo 1.2 Harmattan package for gPodder 3.1.2 has been uploaded to Apps For MeeGo and Nokia Store already, it should hit Apps For MeeGo Staging in a few hours (please do the QA procedure for it then, so it can land in Apps For MeeGo proper) and it should hit Nokia Store in a few days when QA has finished.
