End-of-life announcement: Since we don't use our own app anymore, we are not going to maintain it with newer versions of Confluence. If anyone wants to take over as an open-source project (it's open-source), please tell us!
This version removes any dependency on a Google library.
It also raises the minimum to Confluence 7.0 (Sept. 2019). There is no feature change, so users of C6.x can keep using version 0.8.1.
