We are happy to announce that Spot 1.2.3 has been released.

This maintenance release addresses more portability issues and other minor bugs listed below. It also supports a new SPOT_SATLOG environment variable to extra more statistics from our SAT-based minimization procedures.

It contains contributions from Alexandre Lewkowicz and Étienne Renault.

New in spot 1.2.3 (2014-02-11)

* New features:

- The SPOT_SATLOG environment variable can be set to a filename to obtain statistics about the different iterations of the SAT-based minimization. For an example, see http://spot.lip6.fr/userdoc/satmin.html - The bench/dtgbasat/ benchmark has been updated to use SPOT_SATLOG and record more statistics. - The default value for the SPOT_SATSOLVER environment variable has been changed to "glucose -verb=0 -model %I >%O". This assumes that glucose 3.0 is installed. For older versions of glucose, remove the "-model" option.

* Bug fixes:

- More fixes for Python 3 compatibility. - Fix calculation of length_boolone(), were 'Xa|b|c' was considered as length 6 instead of 4 (because it is 'Xa|(b|a)' were (b|a) is Boolean). - Fix Clang-3.5 warnings. - randltl -S did not honor --boolean-priorities. - randltl had trouble generating formulas when all unary, or all binary/n-ary operators were disabled. - Fix spurious testsuite failure when using Pandas 0.13. - Add the time spent in child processes when measuring time with the timer class. - Fix determinism of the SAT-based minimization encoding. (It would sometimes produce different equivalent automata, because of a different encoding order.) - A the SAT-based minimization is asked for a 10-state automaton and return a 6-state automaton, do not ask for a 9-state automaton in the next iteration... - Fix some compilation issue with the version of Apple's Clang that is installed with MacOS X 10.9. - Fix VPATH builds when building from the git repository. - Fix UP links in the html documentation for command-line tools.
