Kocuj Sitemap plugin has been tested with WordPress 5.0 and is ready for working in it.
From version 2.5.0 of the Kocuj Sitemap plugin all deprecated filters will be removed. All of them has been flagged as deprecated from 2.0.0 version, so there was enough time to migrate into new filters.
From version 2.3.0 support for qTranslate plugin will be dropped. Only qTranslate X plugin will be supported.
