352 It may be worth trying it (even if all bugs are not gone yet)
354 This version may have a bit more of memleaks than 3.3. This will be
355 fixed in a latter release.

377 At least, after 2 years of hard work, we managed to release the 3.3
378 version of the SimGrid framework. There is so many changes that the
379 changelog only lists the most important ones, leaving alone the small
380 improvements, bug fixing and new gadgets.
384 * New simulation models, and improvement of the GTNetS wrapper
386 * Large memory savings (mainly in parser)
387 * Faster (twice faster is not uncommon, and from 20 hours to 2
388 minutes on very large scenarios)
389 * Much better scalability (tested up to 250,000 processes)
391 * Complete regression testing framework so that you can trust the tool
392 * Lot of neat new modules in the XBT toolbox
394 This version was thoroughly tested on linux 32bits and 64bits
395 (debian), as well as Mac OSX (leopard).
397 Unfortunately, our windows-guy left, and we cannot release the windows
398 version at the same time than the other archs. Any help would be
399 really welcomed here.
401 Some of the 96 included test suites are known to fail, but everything
402 should work anyway (don't panic):
403 * The amok module does not work in real deployment ATM, but I don't
404 see this as release critical since I'm not aware of anyone needing
406 * Some tests about the ability of GRAS to receive messages from
407 exotic platforms fail because I've lost access to these platforms
409 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
410 quite puzzled, but I suspect a bug in the test, not in the lib.
411 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
412 sometimes too verbose (when the OS creates hidden files, I
413 suspect), but tesh definitely work as the rest on this arch.
415 We hope to manage to do more timely releases in the future, even if
416 that may turn out difficult since big stuff is coming (I don't say
417 much here for the suspense ;)
419 We hope you'll enjoy this new version, and please report any feedback
420 on the <simgrid-user@lists.gforge.inria.fr> list.
