\b Fix building from the source distribution in a separate directory
from the source.
\b Update broken \c{autoconf} macros.
\b Fix a number of issues when building from source, mostly involving
\c{configure} or dependency generation.
\> In particular, more aggressively avoid cross-compilation problems
on Unix/Linux systems automatically invoking WINE. We could end up
invoking WINE even when we didn't want to, making \c{configure} think
it was running native when in fact cross-compiling.
\b Hopefully fix compiling with the latest versions of MSVC/nmake.
\b Windows host: add embedded manifest file. Without a manifest,
Windows applications force a fixed \c{PATH_MAX} limit to any pathname;
this is unnecessary.
\b Add support VEX-encoded SM4-NI instructions.
\b Add support for VEX-encoded SM3-NI instructions.
\b Add support for VEX-encoded SHA512-NI instructions.
\b \c{PTWRITE} opcode corrected (\c{F3} prefix required.)
\b Disassembler: the SMAP instructions are \c{NP}; notably the
prefixed versions of \c{CLAC} are \c{ERETU}/\c{ERETS}.
\b Add support for Flexible Return and Exception Delivery (FRED): the
\c{LKGS}, \c{ERETS} and \c{ERETU} instructions.
\b Fix external references to segments in the \c{obj} (OMF) and
possibly other output formats.
\b Always support up to 8 characters, i.e. 64 bits, in a
string-to-numeric conversion.
\b Preprocessor: add \c{%map()} function to expand a macro from a list of
arguments, see \k{f_map}.
\b Preprocessor: allow the user to specify the desired radix for an
evaluated parameter. It doesn't make any direct difference, but can be
nice for debugging or turning into strings. See the \c{=} modifier in
\k{define}.
\b Update documentation: \c{__USE_}\e{package}\c{__} is now
\c{__?USE_}\e{package}\c{?__}.
\b Documentation: correct a minor problem in the expression grammar
for \c{D}\e{x} statements, see \k{db}.
\b Preprocessor: correctly handle empty \c{%rep} blocks.
\b Preprocessor: add options for a base prefix to \c{%num()}, see \k{f_num}.
\b Preprocessor: add a \c{%hex()} function, equivalent to \c{%eval()}
except that it producess hexadecimal values that are nevertheless
valid NASM numeric constants, see \k{f_hex}.
\b Preprocessor: fix the parameter number in error messages (should be
1-based, like \c{%}\e{num} references to multi-line macro arguments.)
\b Documentation: be more clear than the \c{bin} format is simply a
linker built into NASM. See \k{binfmt}.
\b Adjust the \c{LOCK} prefix warning for \c{XCHG}.
\> \c{LOCK XCHG }\e{reg}\c{,}\e{mem} would issue a warning for being
unlockable, which is incorrect. In this case the \e{reg}\c{,}\e{mem}
encoding is simply an alias for the \e{mem}\c{,}\e{reg} encoding. However,
\c{XCHG} is \e{always} locked, so create a new warning
(\c{-w+prefix-lock-xchg}) to explicitly flag a user-specified \c{LOCK
XCHG}; default off. Future versions of NASM may remove the \c{LOCK}
prefix when optimization is enabled.
\b Fix broken dependency-list generation.
\b Add optional warnings for specific relocation types
(\c{-w+reloc-*}, see \k{warnings}), default off.
\> Some target environments may have specific restrictions on what
kinds of relocations are possible or allowed.
\b Error out on certain bad syntax in \c{D}\e{x} statements, such as
\c{db 1 2}. See \k{db}.

instructions should have been taking a critical expression all
along.
