18 The "OMG! They Killed Kenny!" version. Major changes:
20 * Java and Ruby bindings were removed from the main archive
21 - They are now distributed separately
22 * GRAS is not considered as stable anymore, but experimental. Sorry.
23 * First support for parallel simulation:
24 - Can run the user code of any simulation in parallel.
25 - Basic support for multi-cores hosts in platform files
26 * Improved P2P support:
27 - Peer tag in platform files for DSL connected nodes
28 - Vivaldi routing scheme for lightweigted yet accurate models
29 * Improved SMPI: Faster Fortran, automatic privatization of C globals
30 * Tracing: trace contains the full platform hierarchy
31 exactly as declared using the ASes of the platform file
33 Plus numerous other goodies (check the ChangeLog for details)

41 The "Winter in Frejus" release. Also known as "ANR/ADT funding helps"
44 * New feature: Model check any simgrid simulation
45 * SMPI: now considered stable
47 - now covers the whole framework
48 - major usability improvements
50 - scalable platform management through hiearchical description
51 - new efficient way to bypass the XML parser
52 * MSG: at last asynchronous functions are available
53 * SIMDAG: many usability improvements (dotloader, ...)
54 * GRAS: finally catch up with latest internal evolutions
56 - Windows port: should be usable now but still considered experimental
57 - Autotools have now been completely removed

77 * the "se habla Java, Ruby 話せます, fala-se Lua (and deaf-friendly)"
78 ~> bindings were greatly improved
79 ~> new tracing infrastructure for better visualization introduced
81 * the "Welcome to configury modernity" release.
82 ~> we switched from autotools to cmake, and improved our cdash

90 The "Desktop Grid needs love too" release (also called "Xmas release").
91 Most important changes:
92 * Big speedup through lazy evaluation of the linear models
93 * Supernovae mode: Compile everything in one unit to improve inlining
94 * Simix network module for internal cleanups
95 * Load DAX of applications into SimDag
96 * Lot of small cleanups and other bug fixes

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

128 This dot release is mainly a maintainance one. Most important changes:
129 * We fixed a large amount of bugs all around
131 * We sanitized the way configuration is handled internally.
132 Try passing --cfg-help to binaries compiled against this version.
134 * SMPI is in better shape: lot of bugs fixing & usability improvements
135 It may be worth trying it (even if all bugs are not gone yet)
137 This version may have a bit more of memleaks than 3.3. This will be
138 fixed in a latter release.

160 At least, after 2 years of hard work, we managed to release the 3.3
161 version of the SimGrid framework. There is so many changes that the
162 changelog only lists the most important ones, leaving alone the small
163 improvements, bug fixing and new gadgets.
167 * New simulation models, and improvement of the GTNetS wrapper
169 * Large memory savings (mainly in parser)
170 * Faster (twice faster is not uncommon, and from 20 hours to 2
171 minutes on very large scenarios)
172 * Much better scalability (tested up to 250,000 processes)
174 * Complete regression testing framework so that you can trust the tool
175 * Lot of neat new modules in the XBT toolbox
177 This version was throughfully tested on linux 32bits and 64bits
178 (debian), as well as Mac OSX (leopard).
180 Unfortunately, our windows-guy left, and we cannot release the windows
181 version at the same time than the other archs. Any help would be
182 really welcomed here.
184 Some of the 96 included test suites are known to fail, but everything
185 should work anyway (don't panic):
186 * The amok module does not work in real deployment ATM, but I don't
187 see this as release critical since I'm not aware of anyone needing
189 * Some tests about the ability of GRAS to receive messages from
190 exotic platforms fail because I've lost access to these platforms
192 * the example/gras/pmm sometimes fails (about 1/10 of cases). I'm
193 quite puzzled, but I suspect a bug in the test, not in the lib.
194 * the tesh auto-tests "fail" on Mac OSX. This is because "rm -rf" is
195 sometimes too verbose (when the OS creates hidden files, I
196 suspect), but tesh definitly work as the rest on this arch.
198 We hope to manage to do more timely releases in the future, even if
199 that may turn out difficult since big stuff is comming (I don't say
200 much here for the suspense ;)
202 We hope you'll enjoy this new version, and please report any feedback
203 on the <simgrid-user@lists.gforge.inria.fr> list.
