libsodium 1.0.6 发布，此版本更新内容如下：
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.
