I have added three new Lighthouse tickets.

2. Update Rails Guide to accurately describe the cache store changes in 3.0 (#6309 Rails Guide Update - ActiveSupport::Cache - Ruby on Rails - rails)
3. Update Rails Guide to describe after transaction callbacks on ActiveRecord added in 3.0 (Dashboard - rails 8994/tickets/6310)
