CodeIgniter 2.2.1 Released

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.

Yes it was.

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.

It's not an issue ... and you've linked us to our own repository.

Yes, I know it is CI's own repository.
I just felt like there was no issue in the earlier version, that's why thought of just notifying if this was may be a ghost coming back at us!  
My bad

Hi.
While I was busy updating my sites I got to a point were I was not sure if had already updated the system folder for one of the sites.

Went to check system\core\CodeIgniter.php
I found define('CI_VERSION', '2.2.0');
So I updated it.

Later I found out that the new 2.2.1 release does not have the equivalent information in:
system\core\CodeIgniter.php

It also has define('CI_VERSION', '2.2.0');
Just in case someone is wondering

I'd just like to say thanks for this release, and for continuing to update the 2.2-stable branch even in the short time since this release. It wasn't an easy decision to choose between 2.x and 3.x three years ago, as it should be for those making that choice now. I'm hoping to make the transition to 3.x soon, but there are fewer things weighing on my mind during the transition period with these updates.

Bonfire

The changes to the license on all the files made merging a little bit of a pain... but I am so very glad you are releasing security updates for 2.2, thanks a lot and keep it coming!
