Early on LLVM's Clang compiler offered much better debugging / error messages than GCC but in the past few years the GNU Compiler Collection developers have been working on generating more helpful messages too.
In a setback to the Christoph Hellwig's efforts to enforce the GPL on code that he wrote in the Linux kernel, his suit against VMware in Germany has been dismissed on procedural grounds. The court ruled that he had not provided enough specificity about the code he was claiming had been used by the company. The merits of the GPL and whether the two main parts of VMware's product constitute a derived work of the kernel were not even considered. There may be another chance for the court to do so, however, as Hellwig will appeal the dismissal.
The Curious Expedition is a roguelike expedition simulation set in the late 19th century, it is soon to leave Early Access and has full Linux support.
It has been on Linux since the early days, so it's one title that has supported us for quite a while. I have never tried it, but the reviews seem pretty good!
Rocket League is way overdue, we all know that, but honestly I am fully expecting it to arrive with the patch due in September named the 'Rumble Update'. This update will come with a bunch of stuff including a new game mode.
I'm speculating of course, so don't take this as solid confirmation of anything. The evidence is starting to come together though and I will be extremely surprised if Linux isn't released with the Rumble update next month.
Every time Rocket League is updated on SteamDB, the Linux depot is now also updated and this has been true for about two weeks now. This is the single most activity the Linux side of RL has ever seen being pushed into branches on Steam.
