CodeIgniter 2.2.1 Released

CI3 will be out soon
This is a security release for our legacy version - being responsible!

Hi,
I had updated my project which is in development stage to CI 2.2.1. While running a cron job via CLI, an error about "Undefined index: REMOTE_ADDR" on line number 352 in core/input.php was shown. I don't think this was there in previous version, i.e. 2.2.0.

Googling about it brought this old link:
https://github.com/bcit-ci/CodeIgniter/issues/1890

I have solved this for my project, but thought of notifying you guys about the issue.

By the way, thanks for the update! Waiting for CI 3 eagerly!
