NEWS for the Nettle 3.9 release
	This release includes bug fixes, several new features, a few
	performance improvements, and one performance regression
	affecting GCM on certain platforms.
	The new version is intended to be fully source and binary
	compatible with Nettle-3.6. The shared library names are
	libnettle.so.8.7 and libhogweed.so.6.7, with sonames
	libnettle.so.8 and libhogweed.so.6.
	This release includes a rewrite of the C implementation of
	GHASH (dating from 2011), as well as the plain x86_64 assembly
	version, to use precomputed tables in a different way, with
	tables always accessed in the same sequential manner.
	This should make Nettle's GHASH implementation side-channel
	silent on all platforms, but considerably slower on platforms
	without carry-less mul instructions. E.g., benchmarks of the C
	implementation on x86_64 showed a slowdown of 3 times.
	Bug fixes:
		* Fix bug in ecdsa and gostdsa signature verify operation, for
		  the unlikely corner case that point addition really is point
		  duplication.
		* Fix for chacha on Power7, nettle's assembly used an
		  instruction only available on later processors. Fixed by
		  Mamone Tarsha.
		* GHASH implementation should now be side-channel silent on
		  all architectures.
		* A few portability fixes for *BSD.
	New features:
		* Support for the SM4 block cipher, contributed by Tianjia
	          Zhang.
		* Support for the Balloon password hash, contributed by Zoltan
	          Fridrich.
		* Support for SIV-GCM authenticated encryption mode,
	          contributed by Daiki Ueno.
		* Support for OCB authenticated encryption mode.
		* New exported functions md5_compress, sha1_compress,
		  sha256_compress, sha512_compress, based on patches from
		  Corentin Labbe.
	Optimizations:
		* Improved sha256 performance, in particular for x86_64 and
		  s390x.
		* Use GMP's mpn_sec_tabselect, which is implemented in
		  assembly on many platforms, and delete the similar nettle
		  function. Gives a modest speedup to all ecc operations.
		* Faster poly1305 for x86_64 and ppc64. New ppc code
		  contributed by Mamone Tarsha.
	Miscellaneous:
		* New ASM_FLAGS variable recognized by configure.
		* Delete all arcfour assembly code. Affects 32-bit x86, 32-bit
		  and 64-bit sparc.
	Known issues:
		* Version 6.2.1 of GNU GMP (the most recent GMP release as of
		  this writing) has a known issue for MacOS on 64-bit ARM: GMP
		  assembly files use the reserved x18 register. On this
		  platform it is recommended to use a GMP snapshot where this
		  bug is fixed, and upgrade to a later GMP release when one
		  becomes available.
		* Also on MacOS, Nettle's testsuite may still break due to
		  DYLD_LIBRARY_PATH being discarded under some circumstances.
		  As a workaround, use
		* make check EMULATOR='env DYLD_LIBRARY_PATH=$(TEST_SHLIB_DIR)'
