v0.5.3 2016-03-21:

• Move from Camlp4 to PPX.
• Tweaked the supporting Cstruct module's API.
• Dh.shared returns option instead of throwing if the public message is degenerate.
• Base64.decode returns option instead of throwing

0.5.2 2015-12-03:

• Avoid including intrinsics-related headers if SSE/AES-NI is disabled.
• Replace opam variable nocrypto-inhibit-modernity with $NOCRYPTO_NO_ACCEL.
• Remove cstruct equality.

0.5.1 2015-07-07:

• Disable AES-NI if not supported in the ./configure step.
• Support the global opam variable nocrypto-inhibit-modernity.

0.5.0 2015-07-02:

• Support for AES-NI and SSE2.
• Support RSA-OAEP and RSA-PSS.
• Drop ctypes for internal C calls.
• Generate smaller secret exponents for DH, making operations on large groups much faster.
• Support dynamic switching of RNG algorithms and decouple Rng from Fortuna.
• Module for injectring entropy into RNG on pure Unix (optional).
• Nocrypto_entropy_lwt.initialize no longer needs to be synchronized on.
• Renamed module signatures and modules containing only signatures from T to S.
• Changes to CTR, CBC, Rsa and Dh APIs.

0.4.0 2015-05-02:

• Module for injecting entropy into RNG on Unix/Lwt (optional).
• Module for injecting entropy into RNG on Mirage/Xen (optional; depends on mirage-entropy-xen).
• API changes in Rng.
• Do not 0-pad DH public and shared representations.
• More named DH groups.

0.3.1 2015-02-01:

• Support for Mirage/Xen (contributed by Thomas Leonard talex5@gmail.com).

0.3.0 2014-12-21:

• Removed ad-hoc key marshalling functions as key material typically comes non-trivially encoded anyways.
• Changed how module interfaces for the packed module are handled: module type of constructs are gone.
• More consistent errors in Rsa.
• Small API breakage here and there.

0.2.2 2014-11-04:

• Replaced hashing sources with the ones from hs-cryptohash (https://github.com/vincenthz/hs-cryptohash) by Vincent Hanquez.
• Renamed various symbols likely to conflict with other crypto libraries.

0.2.0 2014-10-30:

• DSA (initial version contributed by Hannes Mehnert hannes@mehnert.org).
• CCM mode for AES (contributed by Hannes Mehnert hannes@mehnert.org).
• Switched from hand written stubs to ctypes for intefacing with the C code.
• Packed the module to avoid clobbering global namespace; some modules renamed.
• Various bugfixes and improvements.

0.1.0 2014-07-08:

• Initial (beta) release.
