* NEWS: Mention recent removals.

......@@ -63,11 +63,29 @@ New in spot 1.2.4a (not yet released)
- tgba::succ_iter() now takes only one argument. The optional
global_state and global_automaton arguments have been removed.
* Removed features
- The long unused interface for GreatSPN (or rather, interface to
a non-public, customized version of GreatSPN) has been removed.
As a consequence, the we could get rid of many cruft in the
implementation of Couvreur's FM'99 emptiness check.
- Support for symbolic, BDD-encoded TGBAs has been removed. This
includes the tgba_bdd_concrete class and associated supporting
classes, as well as the ltl_to_tgba_lacim() LTL translation
algorithm. Historically, this TGBA implementation and LTL
translation were the first to be implemented in Spot (by
mistake!) and this resulted in many bad design decisions. In
practice they were of no use as we only work with explicit
automata (i.e. not symbolic) in Spot, and those produced by
these techniques are simply too big.
- All support for ELTL, i.e., LTL logic extended with operators
represented by automata have been removed. It was never used in
practice because it had no practical user interface, and the
translation was a purely-based BDD encoding producing huge
automata (when viewed explictely), using the above and non
longuer supported tgba_bdd_concrete class.
