The program is now under a feature freeze until the official Krita 3.0 release, which is scheduled to take place on 27 April. For the next month they are focused on just fixing bugs in this huge release that marks the porting to Qt5 and KDE Frameworks 5. Krita 3.0 also brings Kickstarter-sponsored features of an instant preview, animation support, rulers and guides, grid docker, layer multi-selection handling improvements, support for GImp brushes as images, a revamped layer management panel, and more.
Today's Krita 3.0 Pre-Alpha 3 release has an improved layer docker, updated grid handling, snapping to grids and guides, new export filters, a gradient map filter, and much more.
All of the details on Krita 3.0 Pre-Alpha 3 can be found via the official release announcement at Krita.org.
