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.rdm.backward-compatibility.trailing-slashes application property to true (see rdm-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.

Configuration changelog

This section provides the information about the changes in the configuration files that need to be taken into account when upgrading the solution. In certain cases, the newly introduced default is used or some configuration is required.

The following table lists the changes in the files: added, changed, and removed properties.
