 New since last release:
 
-* Fixed building on new versions of Cygwin (Windows)
-* Export steady-state/transient probabilities from GUI
-* Additional graph zoom functionality on popup menu
-* Added R[C<=k] operator for MDPs (sparse, explicit)
-* Additional functionality in explicit engine
-  - export BSCCs, some LTL
-* New -exportmecs and -exportsccs switches
-* New -sumroundoff switch (used when checking probabilities sum to 1)
-* Update CUDD to version 2.5.0
-* Strategy generation:
-  - improvements in explicit engine implementation
-  - new -exportstrat switch, in development
-* Integer variables can be unbounded (e.g. "x:int;"), for simulation only
-* Small improvements to usability of the GUI simulator transition table
-* Slight change to notation for -exportresults to match -exportmodel
-* Some new '-help xxx' switches (const,simpath,exportresults,aroptions,exportmodel,importmodel)
-* New -exportmodel and -importmodel convenience switches
-* Allow command-line switches of form --sw (as well as -sw)
 * Parametric model checking
-* Fast adaptive uniformisation
-* Export/view labels from GUI
