Unsupported redirect_uri parameter in the logout resource


I would like to know if anyone has an idea why the redirect_uri field (URL parameter) is now deprecated as is show in the source code here : keycloak/LogoutEndpoint.java at 15.0.2 · keycloak/keycloak · GitHub

In the code it indicates that this field should be replaced by postLogoutRedirectUri. Moreover the method parameter is set as deprecated.

Thank you,
