Contrary to most users I actually quite like the new update, especially the updated nginx integration.
One problem I have noticed is that when a function (e.g. brute force protection) locks out an IP the required number of times to qualify for a ban, the IP is not added to the banned users list.
For example this evening I've had 27 email notifications that the same IP has been locked out. The plugin is set to ban an IP after 3 lockouts yet after 27 lockouts it's not in the ban list.
It would be great if this could be fixed as it will mean auto-banning when you team it with an nginx reload cronjob every so many minutes.
