The new support for ECC certificates was previously adding all available options from the output of: openssl ecparam -list_curves it was found that some OSs produce a very large (and confusing) list of possible choices. Code has been changed to cap that output to only: secp384r1 secp521r1 prime256v1 and the "text" will be shown at, respectively: EC-384 EC-521 EC-256 to help make them look less scary.
