We are happy to announce the release of Spot 2.13.2 This is a maintenance release that fixes a few issues. You can find the new release here: http://www.lre.epita.fr/dload/spot/spot-2.13.2.tar.gz See https://spot.lre.epita.fr/ for documentation and installation instructions. Please direct any feedback to <spot@lrde.epita.fr>, or create issues on https://gitlab.lre.epita.fr/spot/spot/-/issues/new New in spot 2.13.2 (2025-06-12) Bugs fixed: - compiling from git with a missing Bison would display a confusing error (Issue #607) - the Python bindings for iterators generated by Swig are not working with libc++ when multiple modules are used. (Everything works with libstdc++.) This caused issues in Mac OS and OpenBSD. This version implements a workaround until Swig is fixed. (Issue #603) - Fix spurious failure of ltlsynt.test on OpenBSD. - difference_word_forq() could return different words on different architectures because the code was iterating on hash_map that can be implemented in different ways. - remove_univ_otf() had a memory-handling bug, that could cause use-after-free errors.
