We are pleased to announce the release of Spot 0.8.2.
Spot is a model-checking library developed collaboratively by LRDE
and LIP6. It provides algorithms and data structures to implement
the automata-theoretic approach to LTL model checking.
This maintenance release fixes a couple of bugs, and implement slight
speedups to the degeneralization and the Safra complementation.
You can find the new release here:

New in spot 0.8.2:
* configure now has a --disable-python option to disable
the compilation of Python bindings.
* Minor speedups in the Safra complementation.
* Better memory management for the on-the-fly degeneralization
algorithm. This mostly benefits to the Safra complementation.
* Bug fixes:
- spot::ltl::length() forgot to count the '&' and '|' operators
in an LTL formula.
- minimize_wdba() could fail to mark some transiant SCCs as accepting,
producing an automaton that was not fully minimized.
- minimize_dfa() could produce incorrect automata, but it is not
clear whether this could have had an inpact on WDBA minimization
(the worse case is that some TGBA would not have been minimized
when they could).
- Fix a Python syntax error in the CGI script.
- Fix compilation with g++ 4.0.
- Fix a make check failure when valgrind is missing.
