+NEWS for the 2.0 release
+
+ This release breaks binary compatibility by splitting the
+ library into two. Some other smaller changes that are not
+ backwards compatible are also done at the same time.
+
+ * The nettle library is split into two libraries, libnettle
+ and libhogweed. libnettle contains the symmetric crypto
+ algorithms that don't depend on GMP, while libhogweed
+ contains the public key algorithms that depend on GMP.
+ Using a single library worked fine with static linking, but
+ not with dynamic linking. Consider an application that uses
+ nettle and which doesn't use any public key cryptography. If
+ this application is linked dynamically to nettle, it would
+ have to be linked also with GMP if and only if public key
+ support was enabled when the nettle library was installed.
+
+ The library names are libnettle.so.3.0 and
+ libhogweed.so.1.0, with sonames libnettle.so.3 and
+ libhogweed.so.1.
+
+ * Function typedefs have been changed to non-pointer types.
+ E.g, the
+
+ typedef void (nettle_hash_init_func *)(void *ctx);
+
+ of previous versions is replaced by
+
+ typedef void (nettle_hash_init_func)(void *ctx);
+
+ This makes it possible to use the type when declaring
+ functions, like
+
+ nettle_hash_init_func foo_hash_init;
+
+ void foo_hash_init(void *ctx) { ... }
+
+ * Changes to the yarrow256 interface. The automatic seed file
+ generation, and the seed_file member in struct
+ yarrow256_ctx, has been removed. To generate a new seed
+ file, use yarrow256_random. The function
+ yarrow256_force_reseed has been replaced by the two
+ functions yarrow256_fast_reseed and yarrow256_slow_reseed,
+ which were previously static. This interface change makes it
+ easier to mix in the current content of the seed file before
+ overwriting it with newly generated data.
+
+ Other changes:
+
+ * The sexp-conv program preserves comments when using the
+ advanced syntax for output. Optionally locks the output
+ file.
+
+ * The base64 decoder recognizes ASCII FF (form feed) and VT
+ (vertical tab) as white space.
+
+ * New x86_64 implementations of AES and SHA1. On a 2.2 GHz
+ opteron, SHA1 was benchmarked at 250 MByte/s, and AES-128 at
+ 110 MByte/s.
+
+ * Performance of AES increased by 20-30% on x86.
+
+ * New programs in the examples directory: erathostenes and
+ next-prime.
