Somehow I missed this from a couple of weeks ago. DOORS 9.3.0.5 has been released.
You can grab it here.
There’s one new feature, according to this page:
Control over the location of key database files
You can now use the registry or the command line to specify the folder that contains the key database files that contain the keys for the Rational Directory Server and Rational DOORS SSL.
The certdb registry entry allows you to specify the folder that contains the key database files. It is also available as a command-line switch (-certdb), where it works alongside -keyDB to control the Rational Directory Server and Rational DOORS SSL authentication.
If you want to put the key database files for Rational DOORS SSL authentication in a separate folder, use the -keyDB switch. The -keyDB switch takes precedence over certdb.
A complete list of fixes can be found on IBM’s site here.
