To fall in line with new CAB forum guidelines there are a few important updates to RapidSSL certificates (including wildcard).

Intermediate CA
The RapidSSL certificate will be issued using an intermediate CA from 9 December 2010. This intermediate certificate must be installed with your certificate to ensure the best browser compatibility.

The intermediate CA can be downloaded from here

Block CSR requests under 2048bits
For certificates that extend beyond 2 years you will not be able to use a CSR request using less than 2048bit. This is to ensure that all certificates are at least 2048bit by 2012.

Free lifetime re-issues
The good news is as reported earlier RapidSSL certificates now include free lifetime re-issues.
