The Darkest Dungeon developers have said the Linux port is practically done, and we should be able to play it soon.
Great news! The update to Arma 3 on Linux has landed, bringing us up to 1.54. Not quite the newest, but better than what we had.
There's plenty of new content and fixes in the 1.54 update you can read up on here.
It's a huge update, but it's not without issues. I have reported them to VP (the porters).
A new update of the Wine Staging software has been released on March 8, 2016, which promises to improve the compatibility with older Windows software even further, as well as to fix various bugs.
Wine Staging 1.9.5 has been seeded to public testers, based on the upstream Wine 1.9.5 software project, and it promises to address many of the issues reported by users since the previous maintenance release, as well as to add better support for many older Windows games and applications.
