I released Contextual Related Posts v3 earlier this week. This is a major version with several new features added, lots of bugs fixed and significant code cleanups.
The biggest change, by far, is the brand new CRP_Query which brings the power and flexibility of WP_Query to this already powerful related posts plugin.
I’ve also added additional styles which are more responsive to mobile browsers including a Grid style, Pinterest style and another two using CSS Grid. I strongly recommend switching to one of these if you have a huge number of mobile users.
Another important change is enhancements to the inbuilt caching. Contextual Related Posts massively speeds up load times with a very aggressive caching mechanism. This version brings an automatic expiry to the caching mechanism as well.
