I love getting the email reminders that something's up with my WP installation. Today I received a note that a plugin 'Ajaxy Search' needed an upgrade.
In this case, the upgrade from 2.8 (maybe, see below) to 3.0 broke the plugin.
It would be great if the email had the current version (again, I think it was 2.8). This way, if the upgrade tanks, I know what was the last version.
Lazy, I know. But it would make WordFence even more essential.
