We released the Expiration application 3.0 for SobiPro. It is compatible with SobiPro 2 and Joomla 4.
The Expiration Applications controls entry's expiration, sends emails to the user to let him know about the expiration, and lets the user renew the entry. Emails can be send to users/authors and/or administrators before and after expiration and on renewing request and renewal itself.
More information are available in the Changelog of the application.
