This is an update to the original version which was released some time ago. I am pleased to say it's still in use by a few server owners and I've had a request to update the plugin to disclude the previously Five played maps from being choosen randomly to play.
Rather than make this a static 5, I mas this number configurable and added an ini file for the plugin, so each server owner can find their own suitable limit (although 5 sounds good, and is the default).
The challenge made me think for a bit at first as to how to go about tackling it, but I decided to go with an ini vector, which was a better option than string compassisons and storage in memory. It also should have a small improvement in performance over the last version (but only ever so slightly).
It's available on the downloads page, here:
