Updates tend to occur every six months or so, and generally run in "themes" (the past few have focused on bucking up the non-English sections of the database, which are rather woefully incomplete at the moment).
It can take a
year or more for a submitted name to get in an update, however.
The lesson here is simple patience. :-)
