[quote author="n0xie" date="1335271522"]...I have seen many projects that changed the API significantly without informing their userbase (enough) and getting a lot of hate for it.
That being said, the change here is minor, so I doubt any major issues will arise.[/quote]
Absolutely and CodeIgniter will never be those guys, but we do have to make changes now and then and a x.0 release is the time to do it.
Some frameworks have put in place major logical rewrites on a 0.x release (which is madness) and others have entirely rewritten everything to the point where you might as well give it a different name.
This is a simple change, that will involve probably an hour of find and replace. If it's in the changelog, the upgrade guide and blog it won't be anything that a developer could miss. A developer should ALWAYS read those before upgrading, and be using a local environment to check their code works before deployment, so this shouldn't be seen as a large problem, or cause any major problems with anyones app.
