+
+       * The _digest functions for hash algorithms, MACs and AEADs no
+          longer take the desired digest size as argument, instead,
+          they always produce the full-size digest. The typedef
+          nettle_hash_digest_func has also been changed accordingly.
+
+          There are two exceptions: CCM and OCB (functions ccm_digest,
+          ocb_digest, ccm_ae128_digest, ocb_aes128_digest, ...). These
+          AEAD algorithms are specified with a variable tag length,
+          which is not a mere truncation of the output.
+
+       * The functions to process complete messages using CCM AES now
+         take a const cipher context as the first argument, e.g,
+         first argument to ccm_aes128_encrypt_message is now a const
+         struct aes128_ctx *. It used to be a struct ccm_aes128_ctx
+         *, where everything but the underlying cipher context was
+         ignored.
+
+       * The SHA3 functions now use the same struct sha3_ctx for all
+         flavors, and the same function sha3_init. Old names, e.g.,
+         sha3_256_ctx and sha3_256_init, are defined as preprocessor
+         aliases, for backwards compatibility.
+
+       C language version:
+
+       * Support for at least C99 is required when building Nettle.
+         In addition, support for alignof and alignas is required;
