Released on October 2nd, 2018. (It was first released on September 27th but we re-released it with a couple of additional bug fixes.)
This is a stable version of b2evolution 6.10.x, recommended for all users.
This release is actually a major milestone in b2evolution's shift from glorified blogs to full-featured Content Management System. In this release you can define Item Types with very refined custom fields. You can then create Items of the desired types. You can use the custom fields in various ways (either in your content or in your skin code) and you can even compare items of same or different types with each other (b2evolution will automatically produce detailed comparison tables like this one).
