 General rule is that new localizations are only included in next release if they are at least 95% complete. Transifex (see below) offers a review functionality, so if you feel like it and are not afraid of responsibility — don't hesitate to ask and we could then have a different deal based on reviewed percentage instead (nothing is set in stone as of now).
 
-## Qt and GTK+ clients
-Translations for Qt and GTK+ clients are managed on Transifex. To help localize, or add your new localization, you'll need to [register on Transifex and join the translation team](https://docs.transifex.com/getting-started/translators) for [Transmission project](https://www.transifex.com/transmissionbt/transmissionbt).
+Translations for Mac, Qt and GTK+ clients are managed on Transifex. To help localize, or add your new localization, you'll need to [register on Transifex and join the translation team](https://docs.transifex.com/getting-started/translators) for [Transmission project](https://www.transifex.com/transmissionbt/transmissionbt).
 
 _GTK+ client translations were previously managed on [Launchpad](https://translations.launchpad.net/transmission/trunk/+pots/transmission), but this is no longer the case. No phrases will be updated there, and none of your translations made there will be integrated back into Transmission._

-## Mac client
-Parts of Mac client translations have been recently uploaded to Transifex as well. We are still in the process of making all of the translations accessible there, including plural forms support and phrases currently only present in .xib files. It will all be there prior to next major release, so stay tuned. You could start localizing now (follow the same steps as above), but be prepared for some inconveniences along the way.
