This month's developer update covers one of the new features in 7.4.4, the old-game directory, and a couple of the new features coming in 7.4.5 and later - new blend mode, and 3D transforms. It talks about some of the new platforms I plan to get Ren'Py running on, and also includes details of the update to the Google Analytics support.
As always, thank you for supporting Ren'Py.
