+.. warning::
+   The latest version only supports HDA v2. If you need to interact with HDA v1, please refer to version 1.14, which is the last compatible one.
+   Keep in mind that HDA v1 will be decommissioned in Q2 2024.
+
+   While v2 is a complete overhaul of the previous version, the client interface is identical in both versions.
+   The most notable change is the query format, that has been greatly simplified.
+   The client, though, is still accepting the old format when possible, converting the query into the new one.
