+NEWS for the Nettle 3.5.1 release
+
+ The Nettle-3.5.1 corrects a packaging mistake in Nettle-3.5.
+ The new directory x86_64/sha_ni were missing in the tar file,
+ breaking x86_64 builds with --enable-fat, and producing worse
+ performance than promised for builds with --enable-x86-sha-ni.
+ Also a few unused in-progress assembly files were accidentally
+ included in the tar file.
+
+ These problems are corrected in Nettle-3.5.1. There are no
+ other changes, and also the library version numbers are
+ unchanged.
+
+NEWS for the Nettle 3.5 release
+
+ This release adds a couple of new features and optimizations,
+ and deletes or deprecates a few obsolete features. It is *not*
+ binary (ABI) compatible with earlier versions. Except for
+ deprecations listed below, it is intended to be fully
+ source-level (API) compatible with Nettle-3.4.1.
+
+ The shared library names are libnettle.so.7.0 and
+ libhogweed.so.5.0, with sonames libnettle.so.7 and
+ libhogweed.so.5.
+
+ Changes in behavior:
+
+ * Nettle's gcm_crypt will now call the underlying block cipher
+ to process more than one block at a time. This is not a
+ change to the documented behavior, but unfortunately breaks
+ assumptions accidentally made in GnuTLS, up to and including
+ version 3.6.1.
+
+ New features:
+
+ * Support for CFB8 (Cipher Feedback Mode, processing a single
+ octet per block cipher operation), contributed by Dmitry
+ Eremin-Solenikov.
+
+ * Support for CMAC (RFC 4493), contributed by Nikos
+ Mavrogiannopoulos.
+
+ * Support for XTS mode, contributed by Simo Sorce.
+
+ Optimizations:
+
+ * Improved performance of the x86_64 AES implementation using
+ the aesni instructions. Gives a large speedup for operations
+ processing multiple blocks at a time (including CTR mode,
+ GCM mode, and CBC decrypt, but *not* CBC encrypt).
+
+ * Improved performance for CTR mode, for the common case of
+ 16-byte block size. Pass more data at a time to underlying
+ block cipher, and fill the counter blocks more efficiently.
+ Extension to also handle GCM mode efficiently contributed
+ by Nikos Mavrogiannopoulos.
+
+ * New x86_64 implementation of sha1 and sha256, for processors
+ supporting the sha_ni instructions. Speedup of 3-5 times on
+ affected processors.
+
+ * Improved parameters for the precomputation of tables used
+ for ecc signatures. Roughly 10%-15% speedup of the ecdsa
+ sign operation using the secp_256r1, secp_384r1 and
+ secp_521r1 curves, and 25% speedup of ed25519 sign
+ operation, benchmarked on x86_64. Table sizes unchanged,
+ around 16 KB per curve.
+
+ * In ARM fat builds, automatically select Neon implementation
+ of Chacha, where possible. Contributed by Yuriy M.
+ Kaminskiy.
+
+ Deleted features:
+
+ * The header file des-compat.h and everything declared therein
+ has been deleted, as announced earlier. This file provided a
+ subset of the old libdes/ssleay/openssl interface for DES
+ and triple-DES. DES is still supported, via the functions
+ declared in des.h.
+
+ * Functions using the old struct aes_ctx have been marked as
+ deprecated. Use the fixed key size interface instead, e.g.,
+ struct aes256_ctx, introduced in Nettle-3.0.
+
+ * The header file nettle-stdint.h, and corresponding autoconf
+ tests, have been deleted. Nettle now requires that the
+ compiler/libc provides <stdint.h>.
+
+ Miscellaneous:
+
+ * Support for big-endian ARM systems, contributed by Michael
+ Weiser.
+
+ * The programs aesdata, desdata, twofishdata, shadata and
+ gcmdata are no longer built by default. Makefile
+ improvements contributed by Jay Foad.
+
+ * The "example" program examples/eratosthenes.c has been
+ deleted.
+
+ * The contents of hash context structs, and the deprecated
+ aes_ctx struct, have been reorganized, to enable later
+ optimizations.
+
+ The shared library names are libnettle.so.7.0 and
+ libhogweed.so.5.0.
