New in spot 1.1.4a (not relased)
* Changes to command-line tools:
- ltlcross has a new option --color to color its output. It is
enabled by default when the output is a terminal.
- ltlcross will give an example of infinite word accepted by the
two automata when the product between a positive automaton and a
negative automaton is non-empty.
- ltlcross can now read the Rabin and Streett automata output by
ltl2dstar. This type of output should be specified using '%D':
ltlcross 'ltl2dstar --ltl2nba=spin:path/to/ltl2tgba@-s %L %D'
However because Spot only supports Büchi acceptance, these Rabin
and Streett automata are immediately converted to TGBA before
further processing by ltlcross. This is still interesting to
search for bugs in translators to Rabin or Streett automata, but
the statistics might not be very relevant.
- To help with debugging problems detected by ltlcross, the
environment variables SPOT_TMPDIR and SPOT_TMPKEEP control where
temporary files are created and if they should be erased. Read
the man page of ltlcross for details.
- There is a new command, named dstar2tgba, that converts a
deterministic Rabin or Streett automaton as output by
ltl2dstar into a TGBA, BA or Monitor. When a deterministic
Rabin automaton is realizable by a deterministic Büchi automaton,
the conversion preserve determinism. (This is not implemented
for Streett.)
- The %S escape sequence used by ltl2tgba --stats to display the
number of SCCs in the output automaton has been renamed to %c.
This makes it more homogeneous with the --stats option of the
new dstar2tgba command.
* All the parsers implemented in Spot now use the same type
to store locations.
* ltlcross has a new option --color to color its output. It is enabled
by default when the output is a terminal.
* ltlcross will give an example of infinite word accepted by the
two automata when the product between a positive automaton and
a negative automaton is non-empty.

* Degeneralization was not indempotant on automata with an accepting
initial state that was on a cycle, but without self-loop.
