- Update of rootfile
- Changelog
    3.10
	This is a maintenance release, including a few each of bug
	 fixes, new features and optimizations.
	The new version is intended to be fully source and binary
	 compatible with Nettle-3.6. The shared library names are
	 libnettle.so.8.9 and libhogweed.so.6.9, with sonames
	 libnettle.so.8 and libhogweed.so.6.
	Bug fixes:
		* Add missing hash functions sha512_224 and sha512_256 to the
		  nettle_get_hashes() list. The name values in the
		  corresponding nettle_hash structs also changed to use
		  underscore instead of dash, for consistency.
		* Fix a few cases of formally undefined calls to memcpy(dst,
		  NULL, 0), resulting from valid calls to, e.g.,
		  sha256_update(ctx, 0, NULL).
	New features:
		* Support RSA-OAEP encryption. Contributed by Nicolas Mora and
		  Daiki Ueno.
		* New function sha3_256_shake_output, new functions
		  sha3_128_init, sha3_128_update, sha3_128_shake,
		  sha3_128_shake_output. Contributed by Daiki Ueno.
		* Added DRBG-CTR with AES256, contributed by Simon Josefsson.
	Optimizations:
		* New combined gcm-aes assembly for powerpc64, contributed by
		  Danny Tsen.
		* New sha256 assembly for powerpc64, contributed by Eric
	          Richter.
		* Improved performance for powerpc64 AES decrypt, by skipping
		  subkey transformations that don't suit the vncipher
		  instructions.
		* Add arm64 CPU feature detection for Android and for Apple systems,
		  contributed by Foolbar and Tim Kosse, prespectively.
	Miscellaneous:
		* New tests for side-channel silence, based on valgrind.
		* Delete all md5 assembly code. Delete all sparc32 assembly code.
    3.9.1
	This is a bugfix release, fixing a few bugs reported for
	 Nettle-3.9. The bug in the new OCB code may be exploitable for
	 denial of service or worse, since triggering it leads to
	 memory corruption. Upgrading from Nettle-3.9 to the new
	 version is strongly recommended.
	The new version is intended to be fully source and binary
	 compatible with Nettle-3.6. The shared library names are
	 libnettle.so.8.8 and libhogweed.so.6.8, with sonames
	 libnettle.so.8 and libhogweed.so.6.
	Bug fixes:
		* Fix OCB loop for processing messages of size 272 bytes or
		  larger. Reported and fixed by Jussi Kivilinna.
		* Fix alignment bug in the new x86_64 non-pclmul assembly
		  implementation of ghash. Reported by Henrik Grubbström.
		* Fix build-time memory leak in eccdata. Reported by Noah
		  Watkins.
