Spot 1.2.3 released - Spot-announce

11 Feb 2014

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.
