Biff https://github.com/jacobobryant/biff/releases/tag/v0.4.2-beta: > Breaking: > • Removed slf4j-nop from the Biff lib's dependencies. Also started using clojure.tools.logging instead of println. To see the logs, you must add slf4j-simple (or another logging implementation) to your deps.edn as described above. See https://github.com/jacobobryant/biff/issues/114 > Changes: > • Made it easier to use LMDB instead of RocksDB. See https://biffweb.com/docs/#unsatisfiedlinkerror > Bugs: > • Fixed biff/crop-day. See https://github.com/jacobobryant/biff/pull/116 > • Added :hx-swap "outerHTML" to . Previously, form elements became nested in the DOM whenever you submitted the bar form in the example app. If you want to apply this fix to an existing project, copy the code from https://github.com/jacobobryant/biff/commit/d35efd68147ee8c0d4c88097fa812eb9a8b4c138.
