CodeIgniter version 2.0 is stable enough to use?

Question

i want to port my application to CodeIgniter but i am wondering whether i should use their v2.0 or v1.72 (then when they release 2.0, upgrade it).

i have never used a framework before so i don't exactly know what implies when upgrading a framework: what does it mean practically - i just move the folders and it will work? or do i have to change a lot of settings, file structure etc? could someone enlighten me about the upgrade process.

and what would you use: v.1.72 or v2.0?

if i'm using the latest version, is there a good documentation for it somewhere so you can read about how to use the new features: packages, drivers and so on.

thanks

Answer 1

If you are selling this app or making something mission critical then of course v1.7.2 is the best choice. That said I have PyroCMS running on v2.0 and since some of my bug-fixes were merged it seems stable enough.

You can read about some of the changes in 2.0 here.

I would image the upgrade process should be straightforward as long as you do not use any features that are different/removed such as plugins. Just take your models, controllers, etc and drop them into the 2.0 framework. Then regression test you whole app, fixing any problems as you see them...
