Nice. It supports lua and mail alerts on changing servers now...

The mail thing seems like a not healthy growth of functionality.

Most people already have logging infrastructure in place for this.

Unix philosophy and all that.

Sending email alerts probably take very little code. Receiving mail is where the complexity is.

Neither seems like good functionality to add to HAProxy. They both seem superfluous and almost antithetical to what it was in 1.5.

Why is it nice?

I can see some value to Lua; it allows for more complex routing rules in a way that's comfortable for a programmer. (This is pretty much what I use Lua for in nginx, too.)

Mail, though--yeah, nope.
