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.
