- Support both /api/v1/fleet and /api/v1/kolide routes in server.
- Add logging for use of deprecated routes.
- Rename routes in frontend JS.
- Rename routes and add notes in documentation.
Notable refactoring:
- Use stdlib "context" in place of "golang.org/x/net/context"
- Go-kit no longer wraps errors, so we remove the unwrap in transport_error.go
- Use MakeHandler when setting up endpoint tests (fixes test bug caught during
this refactoring)
Closes#1411.
