Movable Type 4.2 and MT-Notifier
With the recent release of Movable Type, it has come to my attention that some of you may receive extra notifications sent if you have users subscribed to receive notifications when new entries are added to your blog. This appears to be due to something in the upgrade process, as near as I can tell, saving entries during the upgrade, which triggers a save through MT-Notifier, thinking that it might have something new to send.
If you want to avoid new notifications being sent out, and you are a registered user of MT-Notifier version four, drop me a line prior to upgrading. There is a version of MT-Notifier that I have which will allow you to create history records for all of your subscribers, effectively marking all of your existing subscribers as if they have already been notified of all entries on your system. A bit of a hack, really, but it should work to alleviate this problem.
