Adding CakePHP core features in an older version of CakePHP

Question

I am using CakePHP 2.2 and I will probably need to use SMTP with TTL which is only available at CakePHP 2.3.0.

The additions for this new feature are documented here: https://github.com/cakephp/cakephp/pull/734

And i was wondering where should I add this code in my CakePHP project as I guess the core folders should stay untouched.

Could I do it using the app\lib folder? In that case, how should I add the content? Do I need to follow any structure? How Cake would detect it?

Thanks.

Just follow the CakePHP Migration guide and update to 2.3.

Honestly, I didn't even read through the migration guide, I just swapped into 2.3 and everything has just worked. It doesn't appear that there are many changes to existing code - just improvements / additions, so you'll likely not have to do any code modification.

I like to keep my versions of Cake separate (see advanced installation), but if you're on the normal install, just replace the files within /lib/Cake/ with the new versions files.
