   * add some minor things vor VMS.
 
-  * Don't get the ultimately trusted keys from the secring but store
-    it permanently in the trustdb.  This way we don't need a secring at all.
-    [ currently solved by re-introducing --trusted-key ]  Eventually we
-    will have commands --{add,remove}-trusted-key which keeps them in

   * Use DSA keys with the test suite (partly done)
 
-  * g10/trustdb.c (make_sig_records): fix the fixme.

   * Fix the bug in the mips assembler code
 
   * Add a way to show the fingerprint of an key signator's keys
