## <a name=2017> version 2017 ##
* Better handling of Python 3 on MacOs
* Datafields `Reac_` and `Raux_`, used in accessors, are now forces. New fields `Ireac` and `Iaux_` have been added to access impulsions
* Access to parameters value through variable in `chipy` module
* Use of an `inter_handler_2/3D` inteface module instead of accessing each interaction module separately
* Add a `RecupRlocByPosition` for `CLALp` and `CSASp` contacts
* A partial restart of the post-processing files
* Any GMV related features has been deleted
* Possibility to write **HDF5** files for *DOF*, *GPV* and *Interactions*
* Add bindings to *clipper* library to help with the contact detection between polyhedra
* Use of integer parameters instead of string for contact status in solver
* Several fixes on the timers (especially when involving multi-threading)
* Fix of minor bugs here and there
## Impact on command scripts ##
*`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`):
## Impact for **Core** developpers ##
* `Reac` and `Raux` becoms `Ireac` and `Iaux` in the body type definition
* Many functions/accessor in detection modules disappeared. The main way to access to interaction is now through the **handlers**
* Look into the `inter_handler_2/3D` module, the `public` sections list the available functions in each module. The first parameter is the type of interactions which is an integer from the `parameter` module.
