\H{cl-2.xx} NASM 2 Series
-The NASM 2 series support x86-64, and is the production version of NASM
+The NASM 2 series supports x86-64, and is the production version of NASM
since 2007.
-\S{cl-2.10} Version 2.10
+\S{cl-2.11.05} Version 2.11.05
+
+\b Add \c{--v} as an alias for \c{-v} (see \k{opt-v}), for
+command-line compatibility with Yasm.
+
+\b Fix a bug introduced in 2.11.03 whereby certain instructions would
+contain multiple REX prefixes, and thus be corrupt.
+
+\S{cl-2.11.04} Version 2.11.04
+
+\b Removed an invalid error checking code. Sometimes a memref only with
+a displacement can also set an evex flag. For example:
+
+\c vmovdqu32 [0xabcd]{k1}, zmm0
+
+\b Fixed a bug in disassembler that EVEX.L'L vector length was not matched
+when EVEX.b was set because it was simply considered as EVEC.RC.
+Separated EVEX.L'L case from EVEX.RC which is ignored in matching.
+
+\S{cl-2.11.03} Version 2.11.03
+
+\b Fix a bug there REX prefixes were missing on instructions inside a
+\c{TIMES} statement.
+
+\S{cl-2.11.02} Version 2.11.02
+
+\b Add the \c{XSAVEC}, \c{XSAVES} and \c{XRSTORS} family instructions.
+
+\b Add the \c{CLFLUSHOPT} instruction.
+
+\S{cl-2.11.01} Version 2.11.01
+
+\b Allow instructions which implicitly uses \c{XMM0} (\c{VBLENDVPD},
+\c{VBLENDVPS}, \c{PBLENDVB} and \c{SHA256RNDS2}) to be specified
+without an explicit \c{xmm0} on the assembly line. In other words,
+the following two lines produce the same output:
+
+\c vblendvpd xmm2,xmm1,xmm0 ; Last operand is fixed xmm0
+\c vblendvpd xmm2,xmm1 ; Implicit xmm0 omitted
+
+\b In the ELF backends, don't crash the assembler if \c{section align}
+is specified without a value.
+
+\S{cl-2.11} Version 2.11
+
+\b Add support for the Intel AVX-512 instruction set:
+
+\b 16 new, 512-bit SIMD registers. Total 32 \c{(ZMM0 ~ ZMM31)}
+
+\b 8 new opmask registers \c{(K0 ~ K7)}. One of 7 registers \c{(K1 ~ K7)} can
+be used as an opmask for conditional execution.
+
+\b A new EVEX encoding prefix. EVEX is based on VEX and provides more
+capabilities: opmasks, broadcasting, embedded rounding and compressed
+displacements.
+
+\c - opmask
+\c VDIVPD zmm0{k1}{z}, zmm1, zmm3 ; conditional vector operation
+\c ; using opmask k1.
+\c ; {z} is for zero-masking
+\c - broadcasting
+\c VDIVPS zmm4, zmm5, [rbx]{1to16} ; load single-precision float and
+\c ; replicate it 16 times. 32 * 16 = 512
+\c - embedded rounding
+\c VCVTSI2SD xmm6, xmm7, {rz-sae}, rax ; round toward zero. note that it
+\c ; is used as if a separate operand.
+\c ; it comes after the last SIMD operand
+
+\b Add support for \c{ZWORD} (512 bits), \c{DZ} and \c{RESZ}.
+
+\b Add support for the MPX and SHA instruction sets.
+
+\b Better handling of section redefinition.
+
+\b Generate manpages when running \c{'make dist'}.
+
+\b Handle all token chains in mmacro params range.
+
+\b Support split [base,index] effective address:
+
+\c mov eax,[eax+8,ecx*4] ; eax=base, ecx=index, 4=scale, 8=disp
+
+This is expected to be most useful for the MPX instructions.
+
+\b Support \c{BND} prefix for branch instructions (for MPX).
+
+\b The \c{DEFAULT} directive can now take \c{BND} and \c{NOBND}
+options to indicate whether all relevant branches should be getting
+\c{BND} prefixes. This is expected to be the normal for use in MPX
+code.
+
+\b Add \c{{evex}}, \c{{vex3}} and \c{{vex2}} instruction prefixes to
+have NASM encode the corresponding instruction, if possible, with an EVEX,
+3-byte VEX, or 2-byte VEX prefix, respectively.
+
+\b Support for section names longer than 8 bytes in Win32/Win64 COFF.
+
+\b The \c{NOSPLIT} directive by itself no longer forces a single
+register to become an index register, unless it has an explicit
+multiplier.
+
+\c mov eax,[nosplit eax] ; eax as base register
+\c mov eax,[nosplit eax*1] ; eax as index register
-\b Support for delayed preprocessing \c{%final}
- See \k{final}.
+\S{cl-2.10.09} Version 2.10.09
-\b Support for comment blocks \c{%comment}.
- See \k{comment}.

+\b Fix line continuation parsing being broken in previous version.
+
+\S{cl-2.10.06} Version 2.10.06
+
+\b Always quote the dependency source names when using the automatic
+dependency generation options.
+
+\b If no dependency target name is specified via the \c{-MT} or
+\c{-MQ} options, quote the default output name.
+
+\b Fix assembly of shift operations in \c{CPU 8086} mode.
+
+\b Fix incorrect generation of explicit immediate byte for shift by 1
+under certain circumstances.
+

+\S{cl-2.10.05} Version 2.10.05
+
+\b Add the \c{CLAC} and \c{STAC} instructions.
+
+\S{cl-2.10.04} Version 2.10.04
+
+\b Add back the inadvertently deleted 256-bit version of the \c{VORPD}
+instruction.
+
+\b Correct disassembly of instructions starting with byte \c{82} hex.
+

+
+\S{cl-2.10.03} Version 2.10.03
+
+\b Correct the assembly of the instruction:
+
+\c XRELEASE MOV [absolute],AL
+
+Previous versions would incorrectly generate \c{F3 A2} for this
+instruction and issue a warning; correct behavior is to emit \c{F3 88
+05}.
+
+\S{cl-2.10.02} Version 2.10.02
+
+\b Add the \c{ifunc} macro package with integer functions, currently
+only integer logarithms. See \k{pkg_ifunc}.

\b When optimization is enabled, \c{mov r64,imm} now optimizes to the
shortest form possible between:
\b Add support for x32 ELF (32-bit ELF with the CPU in 64-bit mode.)
See \k{elffmt}.
