+4.0:
+ * Backward incompatible change: all keys passing to encryption
+ functions are slices now, not the fixed arrays. That heavily
+ simplifies the library usage
+ * Fix bug with overwriting IVs memory in gost28147.CFB*crypter
+ * TLSTREE, used in TLS 1.[23], implementation
+ * gost3410.KEK2012* can be used with any curves, not only 512-bit ones
+ * gost3410.PrivateKey satisfies crypto.Signer interface
+ * gost34112012* hashes satisfy encoding.Binary(Un)Marshaler
+ * Streebog256 HKDF test vectors
+
3.0:
* Multilinear Galois Mode (MGM) block cipher mode for
64 and 128 bit ciphers
