MDM 15.4.1 Upgrade Notes

Trailing slashes in API URLs

The default behavior for handling trailing slashes in API URLs has changed. Trailing slashes are now turned off by default, which means that API calls with URLs ending in a forward slash (/) will result in an error.

To enable trailing slashes, set the value of the ataccama.one.mdm.server.backward-compatibility.trailing-slashes and ataccama.one.mda.backward-compatibility.trailing-slashes application properties to true (see MDM Server Application Properties and web-application-reference:mdm:web-app-application-properties.adoc).

Starting from version 17, trailing slashes will no longer be supported. We recommend setting the value to false to ensure smooth upgrade to later versions.
