In dplyr 0.7.0, a number of database and SQL functions moved from dplyr to dbplyr. The generic functions stayed in dplyr (since there is no easy way to conditionally import a generic from different packages), but many other SQL and database helper functions moved. If you have written a backend, these functions generate the code you need to work with both dplyr 0.5.0 dplyr 0.7.0.
