- line numbers
* GUI model editor improvements:
- error highlighting

- undo/redo feature
* Expanded property specification language
- LTL (and PCTL*) now supported
- arbitrary expressions allowed, e.g. 1-P=?[...]
* Expanded property specification language
- LTL (and PCTL*) now supported
- arbitrary expressions allowed, e.g. 1-P=?[...]
- support for weak until (W) and release (R) added
- steady-state operators (S=?[...], R=?[S]) allowed for DTMCs
- optional semicolons to terminate properties in properties files
* Modelling language changes:
- cleaner notation for functions, e.g. mod(i,n), not func(mod,i,n)
- function names can be renamed in module renaming
- language strictness: updates (x'=...) must be parenthesised
- ranges (x=1..3,5) no longer supported
- added conversion tool for old models (etc/scripts/prism3to4)
