597 The "Desktop Grid needs love too" release (also called "Xmas release").
598 Most important changes:
599 * Big speedup through lazy evaluation of the linear models
600 * Supernovae mode: Compile everything in one unit to improve inlining
601 * Simix network module for internal cleanups
602 * Load DAX of applications into SimDag
603 * Lot of small cleanups and other bug fixes

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

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

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