-- PolyMAC spatial discretisation family: three PolyMAC versions are now available in TRUST: 
-    - PolyMAC, which corresponds to the initial PolyMAC implementation. It is not compatible with Pb_Multiphase  but is used in several other applications.
-    - PolyMAC\_P0P1NC, compatible with Pb_Multiphase.  
-    - and PolyMAC\_P0, compatible with Pb_Multiphase. Warning, this last one can be costly on tetrahedral meshes.

-- Conversion to and from an enthalpy form of the energy equation (which is initially in temperature) is now facilitated: the 'fluide\_reel\_base' class contains now a public struct H\_to\_T that is useful to convert, using the chain law, enthalpy derivatives into temperature ones. For codes and application where all derivatives are expressed as a function of the enthalpy, this struct can be now used to safely convert all calls to TPPI methods and Pb_Multiphase fluids/saturation/correlation and source terms.

-- Several improvements/changes have been done around the MED file format, notably the Read\_MED|Lire\_MED keyword:
-    - now relies exclusively on MED groups, not on families. The option 'exclude\_groups' can be used in Read_MED to avoid reading some undesired face groups.
-    - has a new option 'include\_additional\_face\_groups' to read a group of arbitrary faces from a MED file. This can be used with option 'face\_group' to apply Perte\_Charge\_Singuliere on this group of faces. See Perte\_Charge\_Singuliere validation form for example.

-- The LATA format has also been improved and TRUST can now produce single LATA file: the format "single\_lata" can be used, that dumps results in a single binary lata file (Not supported in 64 bits integer build for now). A new interpreter "lml\_to\_lata" has also been added, that can be used to convert lml files to single\_lata format.

 The following developments towards a more performant and more capable TRUST GPU version have been performed:
 
 - Faster setup and less memory needed with option by default changed (HMIS->PMIS selector algorithm) for Nvidia (classical) algebric multigrid: `amgx cg { precond c-amg { } ... }`
 
-- More options for linear solver on AMD: `rocALUTION cg { precond c-amg|sa-amg { [smoother jacobi|gs] [coarse\_grid\_solver LU|inversion|jacobi] [omega double] [coarse\_grids_host int] [impr] } rtol|atol double [ impr ] }`

 - A new method 'initBuildDirectory()' was added in Jupyter validation form Python API. It triggers the build directory creation and copy the 'src' content into it.

 Here are all the syntax changes in the TRUST dataset:
 
 - 'gravity' field is no more read and associated to a medium, syntax is obsolete. It should be read directly in the medium.
 
 - the definition of the 'medium' (Fluid, solid, constituent, ...) can now only read in the problem, and the old syntax (read + association) is not supported anymore.
 
-- Read\_MED|Lire\_MED, Write\_MED|Ecrire\_MED and Champ\_Fonc\_MED*: the old syntax of these keywords is not supported anymore. You now have to use the syntax with braces.
