There is so many changes that the +changelog only lists the most important ones, leaving alone the small +improvements, bug fixing and new gadgets. + +In short: + * Java bindings + * New simulation models, and improvement of the GTNetS wrapper + + * Large memory savings (mainly in parser) + * Faster (twice faster is not uncommon, and from 20 hours to 2 + minutes on very large scenarios) + * Much better scalability (tested up to 250,000 processes) + + * Complete regression testing framework so that you can trust the tool + * Lot of neat new modules in the XBT toolbox + +This version was throughfully tested on linux 32bits and 64bits +(debian), as well as Mac OSX (leopard). + +Unfortunately, our windows-guy left, and we cannot release the windows +version at the same time than the other archs. Any help would be +really welcomed here. + +Some of the 96 included test suites are known to fail, but everything +should work anyway (don't panic): + * The amok module does not work in real deployment ATM, but I don't + see this as release critical since I'm not aware of anyone needing + this right now + * Some tests about the ability of GRAS to receive messages from + exotic platforms fail because I've lost access to these platforms + (such as AIX) + * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm + quite puzzled, but I suspect a bug in the test, not in the lib. + * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is + sometimes too verbose (when the OS creates hidden files, I + suspect), but tesh definitly work as the rest on this arch. + +We hope to manage to do more timely releases in the future, even if +that may turn out difficult since big stuff is comming (I don't say +much here for the suspense ;) + +We hope you'll enjoy this new version, and please report any feedback +on the list. + +Martin Quinson (for Da SimGrid Team)
