@sveneld how does this look to you?

I would normally bump the major package version, but that implies an entirely new package ("Log2") in PEAR world, and I don't know if that's strictly necessary given that the api version has been bumped to indicate changes to the protected interfaces.

I made a refactoring based on phpdoc, in which access levels to functions and properties was described. If someone used internal functions I can not be responsible for such use. Public api was not changed, it just become more typed, what gives more predictable behavior of this package. So maybe if information about php version change and about more strict typing will be written in release it will be enough.
