xHarbour BETA-1.6 for the different platforms are available for download from the download page now.

Here are some of the fixes, and new features offered by Beta-1.6:

xHarbour Core compiler

Generate a line number PCODE for WITH OBJECT line
Added logic to NOT pass BYREF variables which are declared as FIELD into DO ... WITH ...
Emit warning and error messages to stderr instead of stdout
Added missing support for <> operator
Added missing support [-|+] optional repeatable number prefix
Synched support of FIELD-> and _FIELD-> with harbour.slx
Added ANSI 170 and 176 chars to portuguese codepage table
Added ASCII 166 and 167 chars to portuguese codepage table
Fixed HB_SET_COUNT in Include/set.ch to be 20 instead of 15.
New Object engine.
Added generic optimization:
x := x + y -> x += y
x := y + x -> x += y
x := x - y -> x -= y
x := y - x -> x += -y
Due to subsequent optimization of LOCAL += INT and LOCAL -= INT this results in significant optimization of code like:
LOCAL n1 := 1
n1 := n1 + 2
n1 := 2 + n1
n1 := ( n1 + 3 )
n1 := ( ( 4 - (n1) ) )
Improved verbosity of HB_P_LOCALNEARADDINT.

Added fBackword and fOptimized fields to DBSCOPEINFO for RDDs which may want to mark optimization status.
Added fOptimized to DBFILTERINFO (as above).

Added hb_strndup() and hb_strnlen() functions. They works just like GCC
ones and greatly simplify operation on possible un terminated strings

IEEE754 little endian double values on any machine type even if they have
different native double representations. These functions can be used on
such platforms to keep strict binary compatibility (f.e. when
databases/indexes are shared between different systems or user wants to
use common .hrb files.
Added hb_put_ord_ieee754() and hb_get_ord_ieee754() - they store/retrieve
modified IEEE754 double values used by some index formats like CDX and
NSX - they are also platform independent and will work even if natively
different double format is used.
Added hb_get_rev_double()/hb_get_std_double() for machines with strict
alignment when C compilers does not support C extension used in GCC macros.
Added hb_get_le_int64(), hb_get_le_uint64(), hb_put_le_uint64() for compilation
with HB_LONG_LONG_OFF - these functions store/ retrieve 64bit integer
values converting them from/to double.

eliminates very inefficient behavior of in standard NTX files when there is a lot
of duplicated keys
Added optional support for large files up to 4 TB
Note from programmer: Enabling any of the above features cause that indexes
cannot be read by Clipper which does not support them. Indexes with bound
record number have the same format and can be read by Clipper but should
not be modified - to avoid any problems with such unexpected modifications
One bit in NTX header is set, causing Clipper to not be able to open them.
Change internal procedures to eliminate any linear scanning and always use optimal

Changed some internal logic basing on information about pending relations and simplified ADS BOF updating.
Fixed SEEK LAST to work like in Clipper.

Added explicit locking inside APPEND() operation - it resolves the problem with automatic removing locks on appended records after any record movement or updating by ACE library.

The new syntax is: NetRedir(cLocalDevice,cNetDevice,[cPassWord],[lShowError]), if <lShowError> is not passed, the NetRedir will return only .T. or .F.
