Securit:ee 1.3.4 is released today to include a new feature, a couple tweaks, and some bug fixes.
The new feature is from a friend of mine, Jess, and centers around Member Registration in the ExpressionEngine Control Panel. Previously, when you registered a member no email was sent to the user. But now Securit:ee will send a Forgot Password stye email, with expiring link and all the goodies, so new members can be notified of their account. A nice update I think.
There are also the requisite bug fixes for ExpressionEngine version 1.6 that everyone else has been releasing. Take a look at the Change Log for the complete details.
You can download the update from devot:ee.
