1.9.89 - cljs.spec & :preloads

Jun 22, 2016 by David Nolen on Google Groups

This release fixes several cljs.spec issues. It also includes a new compiler option - :preloads. This feature is designed to simplify (but not limited to) the loading of development time side effects such as enabling printing, REPL connections, and browser tool integration. With :preloads you may now specify a sequence of namespaces as symbols to load in order immediately after cljs.core. This also means there's a path for providing typical boilerplate as documented namespaces that users can specify in their dev builds.

As always feedback welcome!
