With a full release expected a bit later this month, Wine 5.0 has a fourth release candidate up to get in some last testing.
Since they're currently in a "code freeze", no big fancy new features are currently being pulled in while they hammer in the final few nails to ensure Wine 5.0 is as stable as possible. For Wine 5.0 RC4 only 15 bugs were noted as fixed. Usual applies, some are old bugs seeing retesting that were fixed in older releases.
A pretty quiet release but that's to be expected both with the festive period, plus winding down to actually get the release out and done. Find the release notes here.
If you need a hand dealing with multiple Wine versions, for different games or applications you can try Lutris.
Once Wine 5.0 is out, another year of full development will begin. What are you hoping to see work in Wine across 2020? Let us know in the comments.
