What is going on with the latest source code release

Overall everything looks cleaner (and thank you:))…However I am
stumbling over issues I did not have with the last release…search is
not working and I get the following error:

uninitialized constant ForumController::OpenStruct

Also I am having spamfilter errors on my deploy server:(

Your IP 66.93.79.146 is listed on the spamhaus.org blacklist. You are

Can anyone help?
