582 This version may have a bit more of memleaks than 3.3. This will be
583 fixed in a latter release.

605 At least, after 2 years of hard work, we managed to release the 3.3
606 version of the SimGrid framework. There is so many changes that the
607 changelog only lists the most important ones, leaving alone the small
608 improvements, bug fixing and new gadgets.
612 * New simulation models, and improvement of the GTNetS wrapper
614 * Large memory savings (mainly in parser)
615 * Faster (twice faster is not uncommon, and from 20 hours to 2
616 minutes on very large scenarios)
617 * Much better scalability (tested up to 250,000 processes)
619 * Complete regression testing framework so that you can trust the tool
620 * Lot of neat new modules in the XBT toolbox
622 This version was thoroughly tested on linux 32bits and 64bits
623 (debian), as well as Mac OSX (leopard).
625 Unfortunately, our windows-guy left, and we cannot release the windows
626 version at the same time than the other archs. Any help would be
627 really welcomed here.
629 Some of the 96 included test suites are known to fail, but everything
630 should work anyway (don't panic):
631 * The amok module does not work in real deployment ATM, but I don't
632 see this as release critical since I'm not aware of anyone needing
634 * Some tests about the ability of GRAS to receive messages from
635 exotic platforms fail because I've lost access to these platforms
637 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
638 quite puzzled, but I suspect a bug in the test, not in the lib.
639 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
640 sometimes too verbose (when the OS creates hidden files, I
641 suspect), but tesh definitely work as the rest on this arch.
643 We hope to manage to do more timely releases in the future, even if
644 that may turn out difficult since big stuff is coming (I don't say
645 much here for the suspense ;)
647 We hope you'll enjoy this new version, and please report any feedback
648 on the <simgrid-user@lists.gforge.inria.fr> list.
