+## <a name=2018> version 2018 ##
+
+ * General fixes in Core, API and documentation
+ * Automatic switch between HDF5 and old OUTBOX directory
+   and associated documentation added
+ * Add `rigidsFromMesh3D` in the preprocessor
+ * `inter_handler_xD_setInternal` accept either a vector to set all value at once,
+   or an integer and a value to set only one component of the internal array
+ * Add triangle intersection detection between `POLYR` contactors
+ * Fixes of periodicity management in 3D
+ * `CLALp` module can now provide for each contact the value of strain
+   of its nearest Gauss point
+ * Default use of MUMPs in 3D if available
+ * Added notebooks to explain how to add user field in Paraview files
+ * Added function `RBDY3_CheckEquilibriumState`
+ * Cleaning of source code (optional non functional `WITH_NEW` compilation flag
+   and all associated code has been removed)

+### Impact on command scripts ###
+
+ * It is now recommended to use:
+
+```python
+chipy.ReadIni(step)
+chipy.WriteOut(freq)
+```
+which will read or write all stored data within the database, instead of specifying all type of files (`DOF`, `GPV`, `VlocRloc`).

 * `Reac_` and `Raux_` fields are not available through getPtrBodyVector (but `Ireac` and Iaux_` are)
 * Old interactions accessors (like `DKDKx_GetNbDKDKx`) disappeared
 * They are replaced by functions of the form `chipy.inter_handler_2D_getNb( inter_type_id )` where `inter_type_id` is an integer
 * The `inter_type_id` is accessible through variables of the `chipy` module (`chipy.DKDKx_ID`):
