582 * We fixed a large amount of bugs all around
584 * We sanitized the way configuration is handled internally.
585 Try passing --cfg-help to binaries compiled against this version.
587 * SMPI is in better shape: lot of bugs fixing & usability improvements
588 It may be worth trying it (even if all bugs are not gone yet)
590 This version may have a bit more of memleaks than 3.3. This will be
591 fixed in a latter release.

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