 PolarSSL ChangeLog (Sorted per branch, date)
 
+TODO: bump SOVERSION for ABI change
+(internal-but-not-static function x509_get_sig_alg() changed prototype)
+(and various x509 structures got a new member)
+
 = PolarSSL 1.3 branch
 Features
    * Add CCM module and cipher mode to Cipher Layer
    * Support for CCM and CCM_8 ciphersuites
+   * Support for parsing and verifying RSASSA-PSS signatures in the X.509
+     modules (certificates, CRLs and CSRs).
 
 Changes
    * Add LINK_WITH_PTHREAD option in CMake for explicit linking that is
