+This version added support for multiple tag filters in service discovery queries, however it introduced a subtle bug where API calls to `/catalog/service/:name?tag=<tag>` would ignore the tag filter _only during the upgrade_. It only occurs when clients are still running 1.2.3 or earlier but servers have been upgraded. The `/health/service/:name?tag=<tag>` endpoint and DNS interface were _not_ affected.
+
+For this reason, we recommend you upgrade directly to 1.3.1 which includes only a fix for this issue.
