Clojurians Log v2

This release reduces latency and write pressure by using multi key transactions of the underlying konserve store, if it supports it.

@alekcz360 This should reduce write pressure and improve latency for you. Lmk whether it helps.

This release removes the store-identity from the configuration check during connection. It turned out to be an overprotective constraint that quite a few people ran into. Thanks to @hoertlehner for opening the issue.
