@wouterj This is actually the 3.0 CHANGELOG file, and I'm not sure if there's even code for this yet - I think Fabien might just be planning ahead, I'm not totally sure. As long as there's not code attached to these changes, then we shouldn't need to worry about them yet - we would update the docs when there are PR's for each change.

@weaverryan - As far as I know, these methods will be deprecated in Symfony 2.2. For instance: on this line:

@deprecated Deprecated in 2.2, to be removed in 3.0. Use setPath instead.

@weaverryan there is already code for this. The old names are deprecated in 2.2 and will be removed in 3.0: https://github.com/symfony/symfony/pull/6738/files#L11R146

So IMO, the 2.2 doc should use the new names
