Dear hAkkers, we—the Akka committers—are pleased to be able to announce the availability of Akka 2.4.0-RC2 (SECOND RELEASE CANDIDATE). This is what we intend to ship as 2.4.0 final unless issues are found, so please test it thoroughly and report back. Failures are important to hear about, but praise also does not hurt :-) We would like to send a special thanks to Akka Persistence plugin maintainer
