Dear all,
now that PPL 0.4.1 is out it is the right time to add new features to the library and to upgrade our development tools. This may bring some instability to the mainline, of course. As far as new features are concerned, I will soon start committing the new constraint system classes. For the tools, I anticipate upgrading to the following versions: GCC 3.1.1, GMP 4.1, Doxygen 1.17 and GLPK 3.2. Please note:
1) upgrading GCC is required in order to work on the Mercury interface; 2) upgrading GMP should not bring any incompatibility; 3) Doxgen 1.17 does not work with our current sources; Doxygen 1.16 will no longer work when I will update our sources to work with Doxygen 1.17; 4) for GLPK we have the same situation we have with Doxygen: after the upgrade, old versions of GLPK will stop working.
All the best
Roberto
