+  Version 0.5 (protocol not changed; ABI changed)
+  - Allow to off turn the cycle detection code in data exchange at
+    compilation time. It should be at run time, but I'm short of time (and
+    the config stuff is still broken). That way, we keep dict of of the
+    critical path, which is good because the performance is poor:
+     - search not dichotomial yet
+     - dynar give no way to access their content and memcpy everytime
+  - In composed data description (struct, ref and so on), stop foolness of
+    keeping the subtype's ID, but store the type itself. This keeps sets out
+    of the critical path, which is good since they rely on dynar and
+    dictionnaries. The only loose of that is that we cannot detect the
+    redeclaration of a structure/union with another content (but I'm not sure 
+    the code detected this error well before anyway). We still can detect
+    the redefinition discrepancy for the other types.
+  - Use a whole bunch of optimisation flags (plus -fno-strict-aliasing since
+    it breaks the code because of type-punning used all over the place).
+    This breaks on all non-gcc architectures (for now).
+    
+  All those changes (plus the buffer of last time) allow me to gain 2 order
+  of magnitude on cruel tests consisting of 800000 array of integers on two
+  level of a hierarchical structure (200 secondes -> 4 secondes)
+  
+  API change:
+    - the selector of reference must now return the type it points to, not
+      the ID of this type.

+  Version 0.4 (protocol changed; ABI not changed)
+  - Allow to pass --gras-log argument to processes in simulation mode. Really.
+  - New debugging level: trace (under debug) to see effect of GRAS_IN/OUT
+  - Implement a buffer transport, and use it by default (it relies on tcp in
+     real life and on sg in simulation).
+    That's a bit hackish since I had a new field to the structure to store
+     its data without interfering with the subtype ones. Inheritance
+     is tricky in C. And that's a kind of reverse inheritance with one class
+     derivating two classes. Or maybe a game with java interfaces. Anyway,
+     that's damn hard in C (at least).
+    Moreover, I got tired while trying to ensure plugin separation and
+     genericity in SG mode. MSG wants me to do weird things, so let's go for
+     cruel hacks (temporarily of course ;).
+     See comment in transport_private.h:71
+  - do not include all the _interface headers in private but in the files
+    which really need them (to cut the compilation time when they are
+    modified)

+  Version 0.3 (protocol not changed; ABI changed)
+  - Major overhault of the datadesc interface to simplify it:
+    - shorted the function names:
+      s/gras_datadesc_declare_struct/gras_datadesc_struct/ and so on
+    - add a trivial way to push/pop integers into the cbps without malloc.
+      This allows to make really generic sub_type description, which simply
+        pop their size of the stack.
+    - add a function gras_datadesc_ref_pop_arr() which does what users want
+      most of the time: Declare a dynamic array (which pops its size of the
+      stack) and declare a reference to it. Poor name, but anyway.
+    - kill the post-send callback, add a post-receive one
+

+  Version 0.2 (protocol changed; ABI changed)
+  - add some testing for cpbs in the test cases, and fix some more bugs.
+    This invalidate again the little64 data file, since I cannot regenerate
+    it myself.
+  - remove an awfull optimization in the logging stuff, allowing me to:
+    - understand it again
+    - learn gcc how to check that the argument match the provided format
+    - fix all errors revealed by gcc after that
+  - internal keys of dict are not \0 terminated. Deal with it properly in
+    loggings instead of segfaulting when the user want to see the logs :-/
+
+2004-07-22 Martin Quinson
+  - Fix some stupid bug preventing cbps (callback postit) from working
+
 2004-07-21 Martin Quinson
-  Version 0.1.2
   - Some documentation cleanups
   - remove the useless last argument of msgtype_declare
   - rename the Virtu functions to fit into the 'os' namespace
+  - move headers src/include -> src/include/gras/ and stop fooling with 
+    gras -> . symbolic link
+  - make distcheck is now successful
