PKCS#1 v2.2 went final on October 27, 2012.  I'm not sure how well our implementations support the new algs:

Version 2.2 updates the list of allowed hashing algorithms to align them with FIPS 180-4, therefore adding SHA-224, SHA-512/224 and SHA-512/256.

The following substantive changes were made:  Object identifiers for sha224WithRSAEncryption, sha512-224WithRSAEncryption and sha512-256WithRSAEncryption were added.
