Thanks for the quick response @andreasgerstmayr! Btw, this page should probably reflect the changes too :) https://grafana.com/docs/tempo/next/setup/operator/#kubernetes

Yes. I wonder if we should add a table to the README of this repo, and link to this table from the Grafana docs instead of always needing to update the Grafana docs.

Maybe a table like this: Tempo Operator	Kubernetes	Tempo
v0.13.0	v1.25 to v1.29	v2.5.0

Similar to the table in the opentelemetry-operator at https://github.com/open-telemetry/opentelemetry-operator?tab=readme-ov-file#opentelemetry-operator-vs-kubernetes-vs-cert-manager-vs-prometheus-operator wdyt @pavolloffay?
