Is OB_SESSION still useful to use?

[eluser]Neil_W[/eluser]
Hello,
From the wiki, OB_Session and DB_Session are quite old. Are they still useful and valid with version 1.7?

Reason I ask is DB_Session, for example, refers to implementing a feature that is now in 1.7 and so I don't see why it is still referenced in the wiki when it could easily confuse people.

I wish to use sessions in CI (for the first time) and want to make them as secure as I can (e.g. I've already trialled using the database implementation of CI using encrypted cookies and storing user data on the database).

I know OB_Session supports session regeneration, etc which would be useful to me.

Thanks for any help.
