Jepsen 0.3.15 is now available. This release fixes a major safety bug in Elle’s rw-register workload, which in turn was caused by two issues with the Bifurcan data structure library. These are now fixed upstream. The control.util/grepkill! function was also nonfunctional, and is now fixed. There are also a few minor dependency bumps, and better support for using roles with generators that depend on (:nodes test).
