Changes between 1.0.1 and 1.1.0 [xx XXX xxxx]
+ *) New flag in ciphers: EVP_CIPH_FLAG_CUSTOM_CIPHER. This means the
+ underlying do_cipher function handles all cipher semantics itself
+ including padding and finalisation. This is useful if (for example)
+ an ENGINE cipher handles block padding itself. The behaviour of
+ do_cipher is subtly changed if this flag is set: the return value
+ is the number of characters written to the output buffer (zero is
+ no longer an error code) or a negative error code. Also if the
+ input buffer is NULL and length -1 finalisation should be performed.
+ [Steve Henson]
+
*) If a candidate issuer certificate is already part of the constructed
path ignore it: new debug notification X509_V_ERR_PATH_LOOP for this case.
