I get the monthly updates for the Jep-derived FMS databases and there's been a large (read several pages) of non-precision approaches deleted in North America in recent months.
Rockwell-Collins for one puts out alerts at least every month with "For immediate attention of the Chief Pilot" on the top line. If you're not getting them or the equivalent, you won't necessarily be aware of a lot of the changes. If you or your company is a subscriber, you can even get all these over the web.
