Prometheus is introducing XOR2, a new and improved chunk encoding format that provides significantly better compression ratios compared to the original XOR encoding. XOR2 is expected to become the stable default compression format in Prometheus 4.0. Currently, Thanos only supports the original XOR encoding and will need to be updated to handle XOR2-encoded chunks to maintain compatibility with future versions of Prometheus.
