+The Restarting Documentation (TRD) Release.
+
+Documentation:
+ - Convert the user manual to Sphinx for improved usability.
+ Unstable version now hosted on https://simgrid.frama.io/simgrid
+ Many glitches remain; stay tuned.
+ - Restrict the Doxygen reference API to the installed header files.
+ (documenting all internals this way is overkill + doxygen scales badly)
+ - New tutorial on S4U (highly inspired from the old MSG one, but with
+ a git repository to fork as a starting point, and a docker image)
+ - Started but not finished a SMPI tutorial inspired from the JLPC'14 one.
+ - The Developper manual is still to be converted (not compiled until then)
+ - Some parts are still missing in this conversion (such as the
+ platform and deployment sections) while others were blindly converted
+ and would need more love (such as the configuration flags).
+ Things will certainly further improve in the future releases.
+
+S4U new features:
+ - Fully reimplement auto_restart mechanism that was utterly broken
+ (fix #22, #131 and #281 that were all very related)
+ - When creating an actor from a function and its parameters,
+ move-only parameters are not allowed anymore, as it would prevent
+ the actor to be restartable if its parameters are consumed on run.
+ - s4u::Io: IOs go asynchronous as activities. This comes with new methods in the
+ s4u::Storage class:
+ - io_init(sg_size_t, s4u::Io::OpType) to create a READ or WRITE asynchronous
+ IO operations that can be started, waited for, or canceled as a regular
+ activity.
+ - read_async(sg_size_t) and write_async(sg_size_t) which are wrappers on
+ io_init() + start()
+
