The 5.0 stable release of Wine is really closing in now, with a fifth Release Candidate being released today with some more bug fixes noted.
No new features again, since they're still in a "code freeze" while they work to make Wine 5.0 as rock solid and stable as possible. Once Wine 5.0 is out fully, another year of development will then begin.
This time around 19 bugs were marked off the list. However, the usual as always applies as some are old bugs that have finally been re-tested so they can close them.
Issues solved include problems with Warframe equipment mouse-overs and the Battle.net application should be a little smoother. Turns out multiple games got improved since Wine 4.3 included FAudio too like Splinter Cell: Blacklist, The Evil Within and Rayman Origins all having open bugs related to broken or missing audio so they've all been marked as solved.
