+SimGrid (3.13) UNRELEASED; urgency=low
+
+ The Easter Trim Release.
+
+ Backwards Compatibility breaks
+   - The option "model-check/sparse-checkpoint" was renamed to
+     "model-check/sparse_checkpoint" as we attempt to unify our naming
+     schemes.
+   - The option smpi/async_small_thres was renamed to smpi/async_small_thresh
+     as we attempt to unify our naming schemes. 
+   - The option smpi/send_is_detached_thres was renamed to
+     smpi/send_is_detached_thresh as we attempt to unify our naming schemes.
+ 
+   - We removed support for writing your simulation in Lua; you can use
+     the Java bindings.
+ 
+ XML platforms:
+ * Switch to platform v4 format.
+   - Rename (power->speed) the attributes describing the amount of flop
+     that a <host>, <peer>, <cluster> or <cabinet> can deliver per second.
+   - In <trace_connect>, attribute kind="POWER" is now kind="SPEED".
+   - The DOCTYPE points to the right URL (this file):
+     http://simgrid.gforge.inria.fr/simgrid/simgrid.dtd
+   - A warning is emitted for unit-less values (they are still accepted).
+     - speed. Default: 'f' or 'flops'. Also defined:
+        'Yf',         'Zf',         'Ef',       'Pf',        'Tf',        'Gf',        'Mf',        'kf'
+        'yottaflops', 'zettaflops', 'exaflops', 'petaflops', 'teraflops', 'gigaflops', 'megaflops', 'kiloflops'
+     - bandwidth. Default: 'Bps' bytes per second (or 'bps' for bits but 1 Bps = 8 bps)
+       Also defined in bytes: 'TiBps', 'GiBps', 'MiBps', 'KiBps', 'TBps', 'GBps', 'MBps', 'kBps', 'Bps'
+       And the same in bits:  'Tibps', 'Gibps', 'Mibps', 'Kibps', 'Tbps', 'Gbps', 'Mbps', 'kbps', 'bps'
+     - latency. Default: 's' second. Also defined:
+       'w' week, 'd' day, 'h' hour, 'm' minute, 'ms' millisecond, 'us' microsecond, 'ns' nanosecond, 'ps' picosecond
+ * Use the tool simgrid_update_xml to upgrade your files. It does not
+   convert the unit-less values. Use tools/sg_xml_unit_converter.py
+   for that (or live with the warnings).
+
+ S4U
+ * s4u::Host is now the prefered public interface to the Host features.
+   sg_host_* functions are C bindings to the exact same behavior
+   MSG_host_* and SD_workstation_* are #define to the sg_host_* ones
+
+ MSG
+ * Kill all deprecated functions. They were deprecated since a few
+   releases anyway, and probably did not even compile anymore.
+
+ Simix
+ * simgrid::simix::kernel() is the closure callback. It ensures that
+    the lambda or closure passed as a parameter will run in kernel mode.
+   Every callbacks should be rewritten to that interface at some point.
+   
+ Surf
+ * Reorganizing and cleaning the internals all around the place.
+
+ SMPI
+ * Remove old default barrier/bcast buggy algorithms (see #18407)
+ * Various bugfixes to handle more codes
+
+ XBT
+ * Kill the setset data container: MC don't use it anymore.
+ * Kill the queue data container: it made more sense with GRAS.
+ * Kill the xbt_peer_t data type: it's useless without GRAS.
+ * New functions:
+   - xbt_dynar_sort_strings(), when the content is char*
+   - xbt_str_parse_int / xbt_str_parse_double, wrapping strtol/strtod
+     They throw exceptions on invalid input.
+ 
+ JAVA:
+ * Remove the ability to write internal plugins in Java. 
+   It may be reintroduced once the ongoing cleanup is done.
