590 The "Desktop Grid needs love too" release (also called "Xmas release").
591 Most important changes:
592 * Big speedup through lazy evaluation of the linear models
593 * Supernovae mode: Compile everything in one unit to improve inlining
594 * Simix network module for internal cleanups
595 * Load DAX of applications into SimDag
596 * Lot of small cleanups and other bug fixes

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

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

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