The first beta version of iOS 8.1 has included the Camera Roll as an option. This being a beta release, it's entirely possible that the feature will not make it to the public release of iOS 8.1. Here's a screenshot of how it appears on my iPad.And I have read rumors that an album very similar to what we have known as Camera Roll is coming back in IOS 8.1 due late in October most likely. Can't remember what they plan to title it in albums but I will prefer it to the new "recently added" album which only shows a very limited amount of photos, something like 30 days worth. I understand you will have to choose it in Icloud Photos--which is something new too,
