0.17.0

Special thanks to our sponsor Matthew Fennell!

3 people contributed to this release: @botantony, @sjaeckel and @jubalh.

The last release (0.16.0) was the first that could be compiled with the Meson build system.
It provided a tarball for autotools and a separate one for meson. The autotools tarball was done
so that distributions don't need dependencies on automake, autoconf and libtool.

Several distributions are dropping vendor tarballs and use git checkouts or autogenerated tarballs nowadays.
Meaning they need to run the above mentioned tools in the case of the autotools build anyways.

So this release will only be shipped with tarballs generated with meson. Profanity can still be compiled with both autotools or meson for easier adjustments. Autotols users just need to generate configure first. The next release will only use Meson. So we enourage everybody to build with Meson arleady and report any bugs they encounter.

We finally reenabled functional tests (along with our existing unit tests) again!
It would be appreciated if we could find people who want to help us expand the unit and functional tests so we are less likely to introduce regressions when we rewrite existing code.

This release also introduces support for libomemo-c.
