+A summary of the major changes found in this release are listed below. A complete list of
+changes is included at the end of this document. Refer to the user‘s manual for a complete
+description of the new, enhanced and revised commands.
+
+
+
+## Enhanced Commands
+
+
+read
+
+read/gocad/file_name/mesh_object_name. Read an ascii GoCad TSURF file (2D).
+
+```
+read/gocad/file_name/mesh_object_name
+```
+
+
+refine/...amr/iprd 
+
+Use amr refinement with an optional direction.
+iprd = 123 refine all hexes. iprd=1 refine along the X direction,
+iprd=2, refine along the y direction, iprd=12,13,23 refine along x,y;
+x,z; y,z respectively. For example:
+```
+refine/constant/imt1/linear/element/1,0,0/ -1.,O.,O./inclusive/amr/12 
+
+will refine all hexs in the x and y directions only.
+```
+
+geniee/cmoname/2dnormal/reference_element_number [addatt] 
+
+For 2d meshes only, this option will attempt to make
+the topological orientation of a triangle, quad or hybrid-triangle-
+quad mesh consistent so that shared edges are traversed on
+opposite directions. This will not be possible if more that 2
+elements share an edge. reference_element_number is the
+element that all other elements will be compared to.
+
+
+dump/elem_adj_node/file_name/cmoname 
+
+Write a list of all elements adjacent to each node to the file fileiname.
+
+
+massage
+
+new option semiexclusive. Refinement will be triggered only by
+edges both of whose endpoints are in the pset. However edges
+with only one or no nodes in the pset might be refined as a result of
+‘Rivara’ refinement Chain.
+
+
+dump/zone_imt
+
+output zone list file associted with imt values but do not output outside lists and multi— material connection lists.
+
+
+createpts/itp
+
+Add nodes to a mesh object by linear interpolation between two point sets
+
+
+
+## Code Changes
+
+
+ung2avs Changed coordinate arrays to double precision arrays. Modified formats [or larger numbers.
+
+refine_nosb, filter, geniee,refine_get_add Changes related to refine/amr option
+
+delaunay2d get rid of n**2 loop (zeroing out ioff)
+
+ntrp_gtg  increase number of significant figures for output.
+
+addmesh_append_nosb Added support of maintaining all attribute types (VINT, VDOUBLE, VCAR) for both
+element based vectors and node based vectors
+
+
+matbld3d_stor Add output of xyz miu/max bounding box of each Voronoi cell. To activate set if_vor_io/2/
+
+mm2000 Added output at the end of mmprint to print out total amount of memory associated With
+memory managed arrays. Changed format in mmprint to allow larger integers.
+
+
+readgmv_ascii changed format so lhe aseii output can exceed lmfllion nodes
+
+dumpgmv_hybrid, readgmv_binary recognize amr variables itetpar, itetkid, itetlev as VINT.
+
+recon, mode add option to turn off recon
+
+rzbrick3 dded options, fixed bugs documented functionality in rzinterp sections of the code.
+This piece of code is nearly the same as the point interpolation code used in extrude, but
+since it required a lot of changes to get it working, 1 decided not to touch the code that extrude uses.
+
+
+rz Fixed error that occured when createpts/line was a line aligned With the y or z axis. Error
+resulted in only cell centered point distributions. Now one can get correct results When ijz=1 and ikz=1.
+
+
+sortbins allow attributes of arbitrary length notjust nnodes or nclemcnts
+
+cmo_setatt_nosb use a longer format When printing a real acalar attribute
+
+dump_material_list fix format statement
+
+radapt initialie ctrl to zero
+
+fillholes Skip holes whose number is greater than lhe current nelements value
+
+extract_interface do not release cmo if it exists - this lost added attributes
+
+recon2_nosb pass iopt2t02 to try4to4xv so as to be able to skip interface recons if desired
+
+filter In cases where the specified pset was empty the code would crash due to asking for zero
+length array. Put in error check to return if pset is empty set.
+
+cel_chain initialize flag to zero
+
+
+
+## Bug Fixes
+
+
+extrude Set, ndimensions_geom of new mesh object.
+
+pset change format to a32 to print entire pset names.
+
+read_sheetij 1ntialize hdrlen to zero so files With no header are read correctly
+
+connect2d got rid 1n**2 loop on resetting ioff
+
+shttstv_nosb added explicit lengths to character comparisons (ickin, ickout)
+
+cel_chain Fix truncated option
+
+refine_edge_list_lg ityp=itettyp(it) was not being set correctly
+
+addmesh_nosb Fixed bug in VCHAR type element attribute
+
+cmo_copyatt_nosb Allow copy ot'node attribute to element attribute and Vice versa only if have the same length.
+
+
+readgmv_ascii fix problem With type ‘lin’
+
+refine_tet_add Return gracefully if nadd=0.
+
+eset Bug in exclusive/pset_get_name  Bug resulted inincorrect result except in the case of tet's
+or quads. Fixed for all element types now.
+
+
+matbld1 changed order in Which work arrays are allocated and released so that they only exist
+when they are really needed. Changed the way row/column index pointers are sorted. 01d
+method used a trick, but the tliek fails when the number of nodes get larger than O(10**7).
+Change to use of a multi—key sort of the isortr and isortc arrays. Added some output to log files.
+
