Due to a problem with using the Transifex client for pulling in new translations into our repository before the last release, gPodder 2.17 was missing some translations that existed in previous versions. This release - gPodder 2.18 - fixes this issue and re-adds all missing translations. The YouTube bugfix that has been the reason for the 2.17 release is obviously also included in this release.
Thanks to Götz Waschk and Tony Mancill for bringing this issue to my attention quickly. Packages for different distributions will appear shortly. Enjoy this new gPodder release!
