+* error in `ComputeRnod` in 3D
+* Correct update of `beta` in `*EXPO_CZM_SPRING` contact laws
 * Quasi-Static time integrator to work with any time step
 * Use `tiny` instead of arbitrary `1e-14` precision check in CZM laws
 * Possibility to have up to 9999999 elements or nodes with `MAILx` bodies
-* Error in `lmgc90_ptc` paraview macro
 * Slight mistakes in tutorials notebooks

 New:
 
+* Contact laws to manage plasticity within CZM
+  * new laws : `IQS_EXPO_CZM_P`, `EXPO_CZM_P`, `IQS_EXPO_CZM_SPRING_P`, `EXPO_CZM_SPRING_P`
+  * same parameters as their `*EXPO_CZM*` counterparts plus two others for plasticity:
+    * `mu_g` to set the rate of damage energy over total energy : $\mu_g = \frac{G_d}{G_f}$
+    * `Eta` a truncation parameter of expo laws
+* Allow to use `visible` status on driven dof of mecaMAILx bodies:
+  * `mecaMAILx_SetVisibleVlocyDrivenDof`
+  * `mecaMAILx_SetInvisibleVlocyDrivenDof`
+  * `mecaMAILx_UpdateVlocyDrivenDofStructures` must be called LAST
+* Support of clipper library version 2
+  * default in new build
+  * activate in existing build with `cmake . -DCLIPPER_VERSION=2`
+* When using `PRPRx_UseNcF2fExplicitDetection`
+  * manage properly the case where the intersection polygon of two faces is not connex
+* Detection method `PRPRx` used by stono
+  * can mix face to face aspect with non-convex ones
+  * manage properly the case where the intersection polygon of two faces is not connex
+  * can use a `decompression` parameter to select contact point position regarding:
+    * the convex hull of the intersection polygon
+    * the intersection polygon and its intersection with the central kernel
+    * manage properly the case where the intersection polygon of two faces is not connex
+  * added keyword:
+    * `PRPRx_UseStoDetection` : activate detection
+    * `PRPRx_ForceF2fDetection` : force face to face within sto detection
+    * `PRPRx_ForceNcDetection` : force non convex within sto detection
+    * `PRPRx_GetF2fOutlines` : get the intersection polygon in the `f2f` structure
+    * `PRPRx_GetF2fStress` : use optimization to evaluate the linear compression stress
+    * `PRPRx_GetF2fCentralKernel` : compute the central kernel
+* Utilities to compute mechanical values of plane contact surface:
+  * `MecaPolyg_CentralKernel`
+  * `MecaPolyg_StressField`
+* Paraview file generation completely reworked:
+  * Now a single paraview file is generated for each time step
+  * This file use the `MultiBlock` logic
+  * The content is almost the same a the union of former files
+  * Exception is the `f2f` file content which is split in two blocks:
+    * `Face2Face` component with the outline of the contact structure
+    * `PressureCenter` component with only the point to draw pressure line
+    * `ContactPointContour` block appears
+    * fields `icdbdy`, `ianbdy`, `icdtac`, `iantac` were added to these blocks
+  * And the `ck` block content now hold only the geometrical part of the central kernel
+  * The argument `write_ck` of the `OpenDisplayFiles` is replaced by `write_f2f` with integer value:
+    * 0: do not write any related block
+    * 1: write only the `Face2Face` and `PressureCenter` blocks
+    * 2: add the `CentralKernel` block to the previous ones
+    * 3: add the `CompressionStress` block to the previous ones
+  * Add `Shape` field with contactor id parameter in vtk `tactor` block
+  * All paraview macros were updated and improved
 * Add support of ubuntu 24
 * Add some basics tests on python/numpy
 * Add a restart parameter to computation macros
-* Paraview macro to draw tubes is available in `src/addons/paraview/LMGC90_gp`
 * Add joint elements:
   * In preprocessor
     * linear bulk elements of type : `J2xx2`, `J3xx3`, `J4xx3`
