What's the CI4 big change?

@albertleao The "upgrading from 3 to 4" link above explains that it is a conversion rather than a simple upgrade. Should anything be added to it?

No no, I wasn't throwing any shade at your documentation. Sorry if you took it that way.

You guys have made it quite clear for those who actually read the documentation that the upgrade to CI4 will be far more intricate than simply pasting in a new system folder.

I was just going by the general consensus among quite a few developers I network with about codeigniter in general. Unfortunately with CI3 being very 'legacy' based and a migration to CI4 being more of a conversion than an upgrade, almost everyone I've talked to is using this opportunity to convert to symfony or laravel. Those who have said they were sticking with CI4 were the same ones who still thought it was going to be an upgrade they could perform in a few hours.

Codeigniter is simply one of the tools you need to learn to be a successful developer. Always add more tools to your coding arsenal!
