New features in Codeigniter 3?

The best problems a found with CI is with POO manage:

- Modularity
- Inheritance
- Exception manage

¿are those issues managed in the new version "3"?

I gather you have some issues or concerns with the way CI3 handles the items you mention, or that you are hoping CI3 will do something some way with them, somehow "managing" them? Your question is not clear.

Actually i am interested in those problems in the framework and will be resolved in new version?.

I love that Framework is really easy and intuitive without intrusive libraries or stupid "arquitectures" into the framework. and by these problems i need to change by another.

Let me rephrase ...

What is "POO manage"? I am not familiar with that term.

"Modularity" - do you have issues or suggestions with how CI3 does or does not deal with "modularity"? coupling? cohesion? coding conventions?

"Inheritance" - do you have issues or suggestions with how CI3 does or does not deal with "inheritance"? classes vs functions?

"Exception manage - do you have issues or suggestions with how CI3 does or does not deal with "exception manage", whatever you mean by that term? Are you talking about the handling of PHP exceptions?
