•	/UPWM/SUPG is now compatible with hexa degenerated into penta elements; previous releases led to negative density error message

•	/DFS/DETPOINT/NODE, DFS/DETLINE/NODE, DFS/DETPLAN/NODE are be options to allow the definition of detonator coordinates using nodes.

•	/INIVOL is now compatible with /TETRA4

•	Artificial Viscosity can now be output in animation files

•	ALE Grid formulation is now input with a generic keyword /ALE/GRID/*

•	/MAT/LAW51 :

-	animation output for pressure, density, sound speed for each phases

-	non-reflecting frontier (NRF) option added derived from Bayliss and Turkell equations applied to multimaterials

•	ALE EULER printout in 0.out files has been improved

•	/MAT/LAW41: default value for IREAC flag has been introduced. Previous version did not provide expected solution if IREAC left to 0

•	/MAT/LAW51: possible erratic energy balance with low fraction of ideal gas (<1%) inside element full of plastic solid (~99%)

•	/ANIM : possible corrupted animation file in case VFRAC (Volume fraction) and SSP (Sound Speed) are used

•	/CAA: Possible Starter message (Error ID 55) while reading the /CAA card

•	/EOS: Possible non-ASCII character in Error ID 824 (WARNING EQUATION OF STATE)

•	Density error message when using streamline upwind (/UPWM/SUPG) with HEXA degenerated into PENTA6

•	LAW20 : /ANIM/ELEM/TEMP has been corrected

•	Fixed a bug where law51 formulation 11 (Drucker Prager) could lead to negative rho error

•	Corrected a possible filling error for /INIVOL LAW51 and iform=10: if the initial volume encompasses several material Ids, a gaz may not be properly initialized

•	Corrected an error in the EOS calculation for with solid material (G>0)

•	/EOS/POLYNOMIAL : Small error in sound speed calculation if Pshift is different from 0.0

•	Fixed issues with /INIVOL and tria elements to determine initial distribution of ALE materials bounded by a given shell component on a specified solid mesh

•	LAW51 iform=10: calculation of sound speed velocity for air component is wrong
