Clojurians Log v2

Hey folks - beta6 is out today 🚀 There's also a preview in here for beta7, which will involve a database migration - this is so that we can better support a wider variety of temporal data shapes before we head towards GA. Also a couple of minor breaking changes to be aware of in the release notes 🔨 Thanks to everyone who's contributed to this release - starting to get excited about GA now 😁
