Comment (by Zach Etienne):

The major update to FLRWSolver was reviewed, merged, and then included in the ET_2025_05 release.

@Roland Haas indicated that there may be one known unresolved issue, namely that the Fortran-based random-number generator originally used does not have a consistent implementation across architectures. Unless there is another ticket for this, I will leave this ticket open until this issue is confirmed to be resolved.
