592 The "Simplicity does not preceed complexity, but follows it" release.
593 Most important changes:
594 * surf and simix modules reworked for simplification.
595 It lays the ground for future extensions and improvements of SimGrid
596 * SMPI was further improved, although not ready for production use yet.
598 On the way, we gained a bit more than 5% on the classical master/slave
599 example. More to come on this in future releases.

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

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