@brainblasted@gnome "It should be emphasised that these changes are confined to Adwaita itself" I find the naming confusing and expect most consumers will too. This really isn't a change in GTK itself (right??), but Adwaita, so why not call it Adwaita 1.1, ship it with some new version and be done?
@solarkraft@gnome Adwaita is shipped as part of GTK, so there's no separate versioning or shipping. During the testing period, the new theme will be shipped with a separate name, and if all goes well it will be merged into GTK.
