If Linux has issues rendering particles, they should now automatically disable themselves and not require the "noparticles" argument. If you still have issues, or have new issues, you may have a distribution with an old libc6 version (like Debian). Use the "beta" branch called "old_libc6" if this is the case. I updated to SDL v2.0.14, which requires more recent libc6.

5089's sequel is making solid progress and more testers have been being picked.
