GNOME 3.33.2 is the second “unstable” release before the next major (“stable”) release, 3.34.
This release is a snapshot of development code. Although it is buildable and usable, it is primarily intended for testing and hacking purposes. GNOME uses odd minor version numbers to indicate development status.
For more information about 3.34, the full schedule, the official module lists and the proposed module lists, please see our 3.33 wiki page: https://www.gnome.org/start/unstable
Final GNOME 3.34 will be released on Wednesday, September 11, 2019.
