# Changelog - 0.2.5 (2026-01-08) * We now check if the ARM cryptographic extensions are available, and, if so, use them to calculate hashes. If they're unavailable we simply use the pure implementation as a fallback. This yields about a 5x performance boost for 'hash' and 3.5x boost for 'hmac' (again, when available). * Allocation for both the 'hash' and 'hmac' functions has been reduced dramatically, mostly by optimising the padding internals, and is now constant with respect to input. - 0.2.4 (2025-12-28) * Adds an 'llvm' build flag and tests with GHC 9.10.3. - 0.2.3 (2025-01-21) * Improves padding handling for the strict bytestring case, yielding performance increases for both 'hash' and 'hmac'. - 0.2.2 (2025-01-07) * Minor bytestring-handling optimisations. - 0.2.1 (2024-10-13) * Adds an INLINE pragma to an internal step function. * 'hmac' no longer calls 'hmac_lazy', which has no practical effect other than to clean up profiling reports generated by GHC. - 0.2.0 (2024-10-07) * 'hmac' and 'hmac_lazy' now hash long keys before computing a HMAC, instead of throwing an error, matching RFC 2104's suggested behaviour. - 0.1.0 (2024-09-14) * Initial release, supporting SHA256 and HMAC-SHA256 on strict and lazy bytestrings.
