1.0.6

• Optimized implementations of Blake2 have been added for modern Intel platforms. crypto_generichash() is now faster than MD5 and SHA1 implementations while being far more secure.
• Functions for which the return value should be checked have been tagged with __attribute__ ((warn_unused_result)). This will intentionally break code compiled with -Werror that didn't bother checking critical return values.
• The crypto_sign_edwards25519sha512batch_*() functions have been tagged as deprecated.
• Undocumented symbols that were exported, but were only useful for internal purposes have been removed or made private:
  sodium_runtime_get_cpu_features(), the implementation-specific crypto_onetimeauth_poly1305_donna() symbols, crypto_onetimeauth_poly1305_set_implementation(), crypto_onetimeauth_poly1305_implementation_name() and crypto_onetimeauth_pick_best_implementation().
• sodium_compare() now works as documented, and compares numbers in little-endian format instead of behaving like memcmp().
• The previous changes should not break actual applications, but to be safe, the library version major was incremented.
• sodium_runtime_has_ssse3() and sodium_runtime_has_sse41() have been added.
• The library can now be compiled with the CompCert compiler.
