#biff https://github.com/jacobobryant/biff/releases/tag/v0.5.0 is out with a fairly significant addition: feature maps now support a :queues key which makes it convenient to create java.util.concurrent.BlockingQueues and associated thread pools for consuming them. Also: • Updated XTDB to 1.22.0 (breaking change, requires re-indexing) • Uses add-libs to add new dependencies from deps.edn on file save, without needing to restart the repl There is some additional discussion of the new queues feature in the https://biffweb.com/p/september-updates/ post.

kc-repl - an interactive took for exploring Apache Kafka clusters. Still a little bit rough around the edges, but should be fully functional. PRs welcomed (I’m using GitHub to track issues), especially if you have any experience getting CI going for a GitHub based project! https://github.com/jeff303/kc-repl
