In versions prior to 1.45.2, users who use the exclusion operator somewhere in their authorization schema; have configured their SpiceDB server such that `--write-relationships-max-updates-per-call` is bigger than 6500; and issue calls to WriteRelationships with a large enough number of updates that cause the payload to be bigger than what their datastore allows; will receive a successful response from their `WriteRelationships` call, when in reality that call failed, and receive incorrect permission check results, if those relationships had to be read to resolve the relation involving the exclusion. Version 1.45.2 contains a patch for the issue. As a workaround, set `--write-relationships-max-updates-per-call` to `1000`."
