Finally, after many years of inactivity, a new release is out for Slacware 15.0.
Major changes of this release: contains the Alire; the GNATStudio is using the binary GNAT Studio Continuous Release 20220512, I failed to build it from source due to lots of dependcies and stuck in the Ada langguare server; a build script that boostrap gprbuild and build/install all the basic packages (XMLAda, GTKAda, Florist, AUnit, GNATCOLL, etc).
