I’ve released version 0.33-1 of the sfsim space flight simulator. This bug-fix release includes three changes aimed at improving stability:

  1. Switched back from Java 27 to the stable Java 25 LTS release.
  2. Fixed infinite recursion when determining which cube face an edge point belongs to.
  3. Fixed an infinite loop caused by a negative opacity step size when computing cloud shadows.
