Re: [ClojureScript] ANN: The REPL, a weekly Clojure/Script newsletter

[Colin Fleming]

Thanks for The REPL, I've been enjoying it very much. I like that it also
has information related to Clojure but not Clojure-specific, such as JVM
performance posts. Nice work!

Cheers,
Colin

Re: [ClojureScript] Proper integration of cljs.test and cljs.spec

[David Nolen]

cljs.spec is not stable or in sync with Clojure 1.9.0-alpha10 clojure.spec
