+ * Documentation update:
+ - New FAQ: "Valgrind spits tons of errors!"
+ - GRAS tutorial containing an introduction both to the GRAS framework
+ and to the used communication model as well as an initiatic tour
+ introducing the most proheminent features. Current tour TOC:
+ # Lesson 0: Installing GRAS
+ # Lesson 1: Setting up your own project
+ # Lesson 2: Exchanging simple messages
+ # Lesson 3: Passing arguments to the processes (in SG)
+ # Lesson 4: Attaching callbacks to messages
+ # Lesson 5: Using globals in processes
+ # Lesson 6: Logging informations properly
+ # Lesson 7: Using internal timers
+ # Lesson 8: Handling errors through exceptions
+ More a due, of course. At least the one explaining how to add data
+ into messages. In the meanwhile, you can check the examples which are
+ still here.

General:
* Port to gcc 4.x
There was a stack corruption somewhere, visible only when optimizing

+ SIMDAG:
+ * This is a NEW module! SimDAG (SD for short) is a revival of the old SG
+ module that enabled to play with Directed Acyclic Graphs. It is built
+ directly on top of SURF and provides an API rather close to the old
+ SG. Some old codes using SG are currently under rewrite to check that
+ all needful functions are provided. [Christophe Thiery]

SURF:

handle parallel tasks yet though. [AL]
* Bug fix: Weights were not correctly set in the network part.
WARNING: This may have resulted in incorrect results with simulations
SURF, MSG, GRAS:
* After a (long ?) discussion on simgrid-devel, we have decided that the
convention we had on units was stupid. That is why it has been decided
- to move from (MBits, MFlops, seconds) fo (Bits, Flops, seconds).

WARNING : This means that all previous platform files will not work as
such with this version! A warning is issued to ask users to update
their files. [AL]
(there was many failure situations I hadn't thought of and that weren't
correctly handled). [AL]
* New function: MSG_host_is_avail indicates you whether a given m_host_t

GRAS:
* New! a real RPC mecanism, as it ought to be since too long. [MQ]

API CHANGE: the callback changed their prototype. Change:
int my_handler(gras_socket_t expeditor, void *payload_data) {
gras_socket_t expeditor=gras_msg_cb_ctx_from(ctx);
and you're set.
* New! function: gras_msg_handleall to deal with all messages arriving

- * New! gras processes display their backtrace when they get a SIGUSR1.

+ * New! function: gras_socket_server_range to get a server socket in a

+ * New! gras processes display their backtrace when they get a SIGUSR1
+ or when Ctrl-C is pressed. Use Ctrl-C Ctrl-C to exit.
Sweet to debug RL processes [MQ]
AMOK:
* Bandwidth module:
- Do not force experiment sizes to be expressed in kb, or it becomes

New! module factorizing code that we wrote over and over [MQ].
XBT:
stdio may need to include it by themselves. [AL]
* Fixed xbt/log.h. A missing SG_BEGIN_DECL prevented compilation with
g++. [AL]
+ * Renamed xbt_host_t into xbt_peer_t since it betterly describes what I
+ meant. This breaks the API of AMOK and of xbt/config. Sorry about this,
+ but I guess that almost nobody used those parts. [MQ]
