releasing 5.0.4

[Dirk Hohndel]

Quick heads up,

Tomorrow (my time, so Friday afternoon / evening European time zones) I
am planning to release the long overdue Subsurface-5.0.4 which will fix
the issue that a few people have with dives imported from Shearwater
Desktop (and a couple other small bugs).

A draft announcement is on GitHub, I will pull translations one more
time before I make the release. If you find any show-stopper bugs in
the meantime, please let me know :)

Thanks
