CodeIgniter 3.0-dev question

[eluser]Unknown[/eluser]
Hi everybody,

I've been using CodeIgniter since two years now and I'm quite happy with it! This forum and its community helped me a lot, but I've never posted anything actually. I could not find any information about CI v3 and my questions, so I thought it was time to create an account ;-)

I'm planning to write my own CMS and recently I've looked at some other frameworks like Laravel 4, Kohana and Yii, but I decided to stick with CodeIgniter. I know the framework quite well and I think the documentation is unmatched. It would cost me a lot of time to switch and the benefits of the other frameworks (authentication, ORM, PHP 5.3) can not persuade me.

My CMS will be a long-term project and I want to write something really great so it has not to be ready in a few weeks. With only 10 issues left on GitHub, I'm considering to write it upon the development version of CodeIgniter 3. I think it will cost more rewriting to switch from v2.1.3 to v3, then to switch from v3-dev to the stable version of v3. What do you think about this?

Thanks in advance!
