Hello! 
jaeger-objectstorage version 3.0.0 is now generally available. 
Our patched Tempo backend that allows Jaeger-UI to consume the traces from Tempo now has a Docker Image to make your migrations a lot easier. (Do avoid the official Tempo image as it has some bugs to make it work with Jaeger)
Documentations are mostly polished and is sufficient enough for you to start working on the integration, although the Kubernetes manifest/operator/charts documentation may come in later (appreciate any contribution!)
And oh. By default traces are flushed every hour. Do change your block_retention in your compactor to more than 1 hour Tempo configuration.
Have fun tracing!
