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

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

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

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