Migrating from CakePHP 2

Here is a list of things that have changed:

Image Helper Changes

The only purpose of the image helper was to generate the versions for the images on the fly depending on your config. This logic behind that was pretty complex and if stored right, there is no need to re-build the whole path.

The new implementation just adds the hash to the path, it doesn't do anything more or cares about the adapter or pathbuilders.

The old implementation is still accessible through the LegacyImageHelper.
