A few weeks ago, Solr 6.0 was released, and right after we also released Solr 5.5.1. That means that most probably 5.5.x is the last in the 5.x series, so start preparing for an upgrade.
Why would you upgrade? Well, Changes gives you 40 bug-reasons and 33 feature-reasons 🙂 Let me highlight the coolest ones:
