Vala 0.38 progress

Maintainers behind Vala compiler, have been busy this cycle.

Vala has a continuous integration machinery, so new features are added to staging branch before to land in master, in order to check some Vala projects can be compiled and their unit tests pass.

Expect more Vala improvements, fixes and backports to 0.34 and 0.36, so you can use them in your favorite distribution.

While 0.34 haven’t been officially declared as a long term support branch, it has received most fixes and backports, so stable releases, like Debian upcoming Strech, can provide reliable, stable and improved experience to developers targeting GNOME 3.22/Gtk+ 3.22 stable releases.

Vala’s bindings using GIR format are updated constantly and because them can be generated automatically from project’s sources, new API additions/changes land in master really fast. Is the case of GTK+ 4.0 unstable; allowing you to create testing/prototypes using latest hot GTK+’s new features, using Vala.
