### Changed
- Search: Users are now findable by their urls.
- Renamed `:await_up_timeout` in `:connections_pool` namespace to `:connect_timeout`, old name is deprecated.
- Renamed `:timeout` in `pools` namespace to `:recv_timeout`, old name is deprecated.
- The `discoverable` field in the `User` struct will now add a NOINDEX metatag to profile pages when false.
