 SimGrid (3.13) UNRELEASED; urgency=low
 
- The Easter Trim Release.
-
- Backwards Compatibility breaks
-   - Some command line options were renamed for consistency sake:
-     - model-check/sparse-checkpoint -> model-check/sparse_checkpoint
-     - smpi/async_small_thres        -> smpi/async_small_thresh
-     - smpi/send_is_detached_thres   -> smpi/send_is_detached_thresh

+ The Half Release, aka the Zeleous Easter Trim.
+ 
+ - We removed half of the lines, that were mostly experimental cruft.
+   v3.12 lasted 286000 lines of code, v3.13 is only 142000 lines
+   (not counting blanks and comments -- according to openhub.net)
+ - The internals are now compiled in C++ (and will soon be clean C++)
+ - We removed 75 klines of XML, 12 klines of Java, 5 klines of cmake, 
+   59 klines of C, etc. We added only 29 klines of C++ in replacement.
+   
+ * Backwards Compatibility breaks
    - Removed Lua simulation bindings (switch to C or Java for that).
      Lua can still be used to describe platforms
    - Removed Java kernel plug-ins.
      Will be reintroduced after the ongoing major internals reorg.
+   - In MSG
+      - the following functions were removed.
+        They were too specific and should be reimplemented in a generic
+        way, with filter function.
+	- MSG_task_listen_from_host
+	- MSG_mailbox_get_count_host_waiting_tasks
+      - MSG_mailbox_put_with_timeout was removed. 
+        Please use MSG_task_send_with_timeout instead.
    - In SimDag 
       - the SD_application_reinit function was removed. It was a noop for a while. 
       - The ACCESS_MODE of SD_workstation has been removed. This feature was not really usable and should soon be

       - VM.setBound(int load) is now VM.setBound(double bound) to meet the MSG semantics. Use VM.getSpeed()*load/100 for the legacy behavior.
    - In CMake
       - option enable_tracing was removed. It was not doing anything since a while.
+   - In the ModelChecker:
+      - the model-checker now ptraces the model-checked process which means
+        you cannot use a debugger on the latter anymore (we might make this
+        optional in the feature);
+      - removed soft-dirty page tracking;
+      - remove model-checked side snapshot management,
+        MC_snapshot() and MC_compare_snapshot();
+      - keep the MC_cut() function as a stub (it was not really working
+        in the previous release).
+	
+ Options:
+ * All options are consistently in kebab-case. Old names are kept as alias.
 
  XML platforms:
  * Switch to platform v4 format.
