580 * surf and simix modules reworked for simplification.
581 It lays the ground for future extensions and improvements of SimGrid
582 * SMPI was further improved, although not ready for production use yet.
584 On the way, we gained a bit more than 5% on the classical master/slave
585 example. More to come on this in future releases.

594 This dot release is mainly a maintenance one. Most important changes:
595 * We fixed a large amount of bugs all around
597 * We sanitized the way configuration is handled internally.
598 Try passing --cfg-help to binaries compiled against this version.
600 * SMPI is in better shape: lot of bugs fixing & usability improvements
601 It may be worth trying it (even if all bugs are not gone yet)
603 This version may have a bit more of memleaks than 3.3. This will be
604 fixed in a latter release.

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