When you deploy a Generation 2 application with a custom `domain:` the release process will now search for an existing certificate in your account that can satisfy the request and use it if available.

- [#2673](https://github.com/convox/rack/pull/2673) use an existing certificate for services if available [[@ddollar](https://github.com/ddollar)]
- [#2674](https://github.com/convox/rack/pull/2674) Use the unaltered request uri including the query string for the http proxy [[@subwai](https://github.com/subwai)]
- [#2675](https://github.com/convox/rack/pull/2675) prevent buffer overwrite on log stream [[@ddollar](https://github.com/ddollar)]
