Update to 2.05.01:

Version 2.05.01

    * Fix the -w/-W option parsing, which was broken in NASM 2.05.

Version 2.05

    * Fix redundant REX.W prefix on JMP reg64.
    * Make the behaviour of -O0 match NASM 0.98 legacy behavior.
    See section 2.1.22.
    * -w-user can be used to suppress the output of %warning
    directives. See section 2.1.24.
    * Fix bug where ALIGN would issue a full alignment datum instead
    of zero bytes.
    * Fix offsets in list files.
    * Fix %include inside multi-line macros or loops.
    * Fix error where NASM would generate a spurious warning on
    valid optimizations of immediate values.
    * Fix arguments to a number of the CVT SSE instructions.
    * Fix RIP-relative offsets when the instruction carries an immediate.
    * Massive overhaul of the ELF64 backend for spec compliance.
    * Fix the Geode PFRCPV and PFRSQRTV instruction.
    * Fix the SSE 4.2 CRC32 instruction.

Version 2.04

    * Sanitize macro handing in the %error directive.
    * New %warning directive to issue user-controlled warnings.
    * %error directives are now deferred to the final assembly phase.
    * New %fatal directive to immediately terminate assembly.
    * New %strcat directive to join quoted strings together.
    * New %use macro directive to support standard macro directives.
    See section 4.6.4.
    * Excess default parameters to %macro now issues a warning by
    default. See section 4.3.
    * Fix %ifn and %elifn.
    * Fix nested %else clauses.
    * Correct the handling of nested %reps.
    * New %unmacro directive to undeclare a multi-line macro. See
    section 4.3.10.
    * Builtin macro __PASS__ which expands to the current assembly
    pass. See section 4.11.9.
    * __utf16__ and __utf32__ operators to generate UTF-16 and
    UTF-32 strings. See section 3.4.5.
    * Fix bug in case-insensitive matching when compiled on platforms
    that don't use the configure script. Of the official release
    binaries, that only affected the OS/2 binary.
    * Support for x87 packed BCD constants. See section 3.4.7.
    * Correct the LTR and SLDT instructions in 64-bit mode.
    * Fix unnecessary REX.W prefix on indirect jumps in 64-bit mode.
    * Add AVX versions of the AES instructions (VAES...).
    * Fix the 256-bit FMA instructions.
    * Add 256-bit AVX stores per the latest AVX spec.
    * VIA XCRYPT instructions can now be written either with or
    without REP, apparently different versions of the VIA spec
    wrote them differently.
    * Add missing 64-bit MOVNTI instruction.
    * Fix the operand size of VMREAD and VMWRITE.
    * Numerous bug fixes, especially to the AES, AVX and VTX instructions.
    * The optimizer now always runs until it converges. It also
    runs even when disabled, but doesn't optimize. This allows most
    forward references to be resolved properly.
