[-] Fixed small bug with DT directive far pointer syntax. [+] Added "plt" operator for the ELF output format.

[+] Added FSTENVW/FSTENVD/FSAVEW/FSAVED mnemonics.
version 1.67.29 (Nov 15, 2008)
[+] Added optional symbolic information output, and a set of tools that extract
various kinds of information from it.
[+] Allowed RVA operator to be used in COFF object format.
[-] Corrected the FIX directive to allow names of preprocessor's directives to be
used as prioritized symbolic constant name.
version 1.67.28 (Nov 06, 2008)
[+] Added EFI/EFIBOOT/EFIRUNTIME subsystem keywords for PE format (experimental
feature, still needs to be tested).
[-] Fixed a bug in preprocessor which caused some problems with DISPLAY directive
output in some cases.
[-] Fixed a bug that allowed to define a symbol named "eip" or "rip".
[-] Fixed a problem with assembling MOVQ RAX,XMM0 instruction.
version 1.67.27 (Jul 12, 2008)
[-] Fixed a bug which caused instructions from JCXZ/LOOP family to be incorrectly
assembled when requiring 67h prefix and provided with "$" operand.
[-] Definition of macro with the same name as one of the preprocessor's directives
is no longer allowed.
[-] Fixed REPT directive to check out validity of its parameters even when the
count is zero.
[-] Fixed VMREAD/VMWRITE syntax in the USE64 mode.
[-] Corrected MZ header generation and handling for the case when the last page of
executable contains the round 512 bytes.
version 1.67.26 (Jan 27, 2008)
[+] Added partial SSE4 support (a couple of instructions left to be implemented
in the next releases)
[+] Added GETSEC instruction for the SMX functions calling.
[-] Some fixes and rearrangements in the DOS version.
version 1.67.25 (Dec 30, 2007)
[-] Fixed a couple of bugs related to undefined symbol error signaling.
version 1.67.24 (Dec 03, 2007)
[+] Added "-d" option to allow predefining symbolic constants from command line.
[-] Changed some of the error messages to be more informative.
version 1.67.23 (Sep 08, 2007)
[+] Added "static" keyword for the "public" directive in COFF format.
[-] Redirected error information into stderr.
version 1.67.22 (Aug 05, 2007)
[+] Allowed to check "@b" and "@f" symbols with "defined" operator.
[+] Allowed "as" operator to specify the output file extension when
placed at the end of the "format" directive line.
[-] Fixed a bug with stack size declaration in PE64 format that
caused assembler to crash.
[-] Corrected the VMREAD and VMWRITE instructions to allow registers
in place of memory operands.
[-] Corrected a mistake that made PLT operator not work correctly with
the CALL instruction.
version 1.67.21 (Feb 17, 2007)
[+] Allowed 32-bit relocations in PE64 output format.
[-] Fixed a bug that caused "push cr0" error to go unnoticed by assembler.
version 1.67.20 (Feb 12, 2007)

The symbol escaping now has always the higher priority than symbol conversion,
and both have higher precedence than concatenation.
[-] Fixed problems with logical expression parser to handle correctly comparing
values containing round brackets with the EQ or EQTYPE operator.
The only limitation now is that when you use round brackets to enclose some
logical expressions, they must be paired everywhere inside those expressions.

[-] Fixed a bug that caused over-repeated processing of macro operators when
many embedded macros were placed in one line
