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

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