NEWS

 New in spot 0.7.1a:
 
-  * Spot can read DiVinE models.  See iface/dve2/README for details.
-  * The experimental Nips interface has been removed.
-  * The dotty_reachable() has a new option "assume_sba" that can
-    be used for rendering automata with state-based acceptance.  In
-    that case, acceptance states are displayed with a double circle.
+  * Major new features:
+    - Spot can read DiVinE models.  See iface/dve2/README for details.
+    - The experimental Nips interface has been removed.
+    - The genltl tool can now output 20 differents LTL formula families.
+      It also replace the LTLcounter Perl scripts.
+  * Major interface changes:
+    - The destructor of all states is now private.  Any code that looks like
+      "delete some_state;" will cause an compile error and should be
+      updated to "some_state->destroy();".  This new syntax is supported
+      since version 0.7.
+  * Minor changes:
+    - The dotty_reachable() function has a new option "assume_sba" that
+      can be used for rendering automata with state-based acceptance.
+      In that case, acceptance states are displayed with a double
+      circle. ltl2tgba (both command line and on-line) Use it to display
+      degeneralized automata.
+  * Internal improvements:
+    - The on-line ltl2tgba CGI script uses a cache to produce faster
+      answers.
+    - Better memory managementmanagment for the states of explicit
+      automata.  Thanks to the aforementioned ->destroy() change, we
+      can avoid cloning explicit states.
+    - tgba_product has learned how to be faster when one of the operands
+      is a Kripke structure (15% speedup).
+    - The reduction rule for "a M b" has been improved: it can be
+      reduced to "a & b" if "a" is a pure eventuallity.
