JSS 3.2 is now in beta. The source has been tagged with JSS_3_2_BETA1, and some builds have been posted to ftp://ftp.mozilla.org/pub/security/jss/releases/JSS_3_2_BETA1/ (Solaris and Windows).
The JAR files in this release (xpclass.jar/jss32.jar and xpclass_dbg.jar/jss32_dbg.jar) have been signed with a JCE code-signing cert, because they now contain a JCE provider. The main feature of this new release is increased support for the JCA/JCE provider model. Several new implementations have been added in the org/mozilla/jss/provider/ hierarchy. Please file bugs against the JSS product in bugzilla (http://bugzilla.mozilla.org/enter_bug.cgi?product=JSS).
