Threema 2.8 for Android is now available. Among other improvements, this update introduces support for text formatting. You can now spice up your messages by writing words in bold, italic, and strikethrough type. To do this, simply enclose a word or a sentence in the appropriate character: * bold *, _ italic _, and ~
strikethrough ~. Support for this feature on iOS and Windows Phone is in the works.
The 2.8 update also includes various bug fixes and performance improvements. For all the details, please consult the change log.
