ANN: ClojureScript 0.0-2341, Improved Analysis & Transducers

[David Nolen]

ClojureScript, the Clojure compiler that emits JavaScript source code.

README and source code: https://github.com/clojure/clojurescript

New release version: 0.0-2341

Leiningen dependency information:

[org.clojure/clojurescript "0.0-2341"]

This releases comes with considerably better analysis. Vars from other
namespaces are finally also verified. Protocols previously saw very
little analysis support. Protocol method implementations are now
checked for validity against the declared protocol.

Transducers are also now in sync with Clojure 1.7.0-alpha2

Feedback welcome!

### Enhancements
* transducers

### Fixes
* CLJS-704: warn if protocol extended to type multiple times in extend-type
* CLJS-702: warn if protocol doesn't match declared
* CLJS-859: use https for the bootstrap script
* CLJS-855: combinatorial code generation under advanced
* CLJS-858: resolve-existing var does not check vars outside current ns
* CLJS-852: same group-by as Clojure
* CLJS-847: Safari toString fix
* CLJS-846: preserve namespace metadata

I just cut 0.0-2342, the only change is a updated dependency on
tools.reader 0.8.9 - this fixes an issue where source metadata would
leave into the runtime.

It would be better that the jira issues have links.

Thanks for the release! Especially CLJS-855 :-)

Both the previous and this causes the following warnings with core.async:

WARNING: Use of undeclared Var cljs.core.async/do-alts at line 62 file:../.m2/repository/org/clojure/core.async/0.1.338.0-5c5012-alpha/core.async-0.1.338.0-5c5012-alpha.jar!/cljs/core/async/impl/ioc_helpers.cljs

I think perhaps the time has come for a cross-project automated-test server for CLJS and the 10-15 most common CLJS libraries. My understanding is at the level to understand the need, and I could muster a server.... but I am not "wired in" to the CLJS development community enough to know how to do it. Hmmm.

Those are errors in core.async already fixed in master.

Do you know off-hand if those fixes are in 0.1.346.0-17112a-alpha which is the latest available version of core.async?

Yes the fixes should be in the latest release core.async.
