New in spot 2.10.5 (2022-05-03)

Bugs fixed:

- reduce_parity() produced incorrect results when applied to automata with deleted edges.

- An optimization of Zielonka could result in incorrect results in some cases.

- ltlsynt --print-pg incorrectly solved the game in addition to printing it.

- ltlsynt would fail if only one of --ins or --outs was set, and if it was set empty.

- Work around a portability issue in Flex 2.6.4 preventing compilation on OpenBSD.

- Do not use the seq command in test cases, it is not available everywhere.

- Do not erase the previous contents of the PYTHONPATH environment variable when running tests, prepend to it instead.

- Simplify Debian instructions for LTO build to work around newer libtool version.

- Fix invalid read in digraph::sort_edges_of_(), currently unused in Spot.
