Dear Fast Downward group,
we are happy to announce the release of Fast Downward 24.06.1.
Fast Downward 24.06.1 fixes a serious bug in Fast Downward 24.06 when
using merge-and-shrink heuristics:
The options for the merge_and_shrink evaluator were considered in the
wrong order. For example, the boolean option prune_unreachable_states
was interpreted as max_states, so that max_states was set to 0 or 1
based on the boolean flag. This is now fixed.
If you ran any experiments with merge-and-shrink heuristics with Fast
Downward 24.06, please re-run them. Earlier releases are not affected.

Happy planning,
the Fast Downward team
