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

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

66 The "Easter in Cargese" release. Also known as (major changes):
68 * the "se habla Java, Ruby 話せます, fala-se Lua (and deaf-friendly)"
69 ~> bindings were greatly improved
70 ~> new tracing infrastructure for better visualization introduced
72 * the "Welcome to configury modernity" release.
73 ~> we switched from autotools to cmake, and improved our cdash

81 The "Desktop Grid needs love too" release (also called "Xmas release").
82 Most important changes:
83 * Big speedup through lazy evaluation of the linear models
84 * Supernovae mode: Compile everything in one unit to improve inlining
85 * Simix network module for internal cleanups
86 * Load DAX of applications into SimDag
87 * Lot of small cleanups and other bug fixes

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

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

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