+SkyWalking CLI and SkyWalking OAP communicate with different query versions, here is a summary of the compatible versions of both.
+Note that many queries in older CLI releases can still work with new OAP versions and vice versa because most query APIs are forward-compatible.
+The compatibility table here only lists fully compatible OAP versions, which mean new query APIs are implemented in this specific version.
