+ GRAS:
+ * New module mecanism where user code can use per process globals [Mt]
+ This is similar to gras_userdata_*() functions, but for libraries. It
+ factorize some code developped over and over in the examples and AMOK.
+ It has still to be documented and used (only amok/peermanagement is
+ converted for now).
+
+ AMOK:
+ * Do really rename the hostmanagement module to peermanagement. [Mt]
+ Ie, rename functions from amok_hm_* to amok_pm_*. This breaks the API,
+ but this is rather new and this was documented in the module
+ documentation (poor excuse, I admit)
+
+ Documentation update:
+ * New FAQ: "Valgrind spits tons of errors!" [Mt]
+ * GRAS tutorial [Mt]
+ It contains:
+ - an introduction to the framework and to the used communication model
+ - an initiatic tour introducing the most proheminent features:
+ # 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.
+
+ SIMDAG:
+ * A sequential mode has been added to the workstations. When a workstation
+ is in sequential mode, it can execute only one task, and the other tasks
+ are waiting in a FIFO. [Christophe Thiery]
+
+ SURF:
+ * The KCCFLN05 workstation model now handles parallel tasks. It is the
+ model for SIMDAG. [Christophe Thiery]

+
+ 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]

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]

correctly handled). [AL]
* New function: MSG_host_is_avail indicates you whether a given m_host_t

GRAS:

API CHANGE: the callback changed their prototype. Change:
int my_handler(gras_socket_t expeditor, void *payload_data) {

and you're set.
* New! function: gras_msg_handleall to deal with all messages arriving

+ * 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:

* Peer management module:

meant. This breaks the API of AMOK and of xbt/config. Sorry about this,
- but I guess that almost nobody used those parts.
