3.0.0-alpha21 on clojars. I did a bit of work around the merge functions to allow the mark/sweep behavior to be turned on for things like merge-component. Also cleaned up those internals a bit. The tests may not pass on CI due to some spec issues in dependent lib. Working on getting that fixed. This version also has support for network aborts, alternate default config edn, and a bugfix to the legacy union router. Also, fulcro-spec 3.1.4 is out with some terminal reporter output improvements, and a better story for setting that config (see cfg in that ns). This should make the REPL running a bit nicer (https://github.com/fulcrologic/fulcro-spec#new-repl-runner)
