   Bugs fixed:
 
+  - spot::translator was not applying Boolean sub-formula rewritting
+    by default unless a spot::option_map was passed.  This caused some
+    C++ code for translating certains formulas to be noticeably slower
+    than the equivalent call to the ltl2tgba binary.

   - The remove_ap algorithm was preserving the "terminal property" of
     automata, but it is possible that a non-terminal input produces a
     terminal output after some propositions are removed.
