CHANGES: Add note about the refactoring of SM2 EVP_PKEYs
Changes between 1.1.1 and 3.0.0 [xx XXX xxxx]
+ *) Reworked the treatment of EC EVP_PKEYs with the SM2 curve to
+ automatically become EVP_PKEY_SM2 rather than EVP_PKEY_EC.
+ This means that applications don't have to look at the curve NID and
+ 'EVP_PKEY_set_alias_type(pkey, EVP_PKEY_SM2)' to get SM2 computations.
+ However, they still can, that EVP_PKEY_set_alias_type() call acts as
+ a no-op when the EVP_PKEY is already of the given type.
+
+ Parameter and key generation is also reworked to make it possible
+ to generate EVP_PKEY_SM2 parameters and keys without having to go
+ through EVP_PKEY_EC generation and then change the EVP_PKEY type.
+ However, code that does the latter will still work as before.
+ [Richard Levitte]

*) Deprecated EVP_PKEY_decrypt_old(), please use EVP_PKEY_decrypt_init()
and EVP_PKEY_decrypt() instead.
Deprecated EVP_PKEY_encrypt_old(), please use EVP_PKEY_encrypt_init()
