I am happy to announce a long-overdue core.async release.

Dependency info:  [org.clojure/core.async "0.2.371"]

There are a few new features in this release:

1) *promise-chan* is a function that returns a new kind of channel (with a 
custom buffer) with promise semantics. Specifically, channels make a 
one-time transition to having a deliverable value. *promise-chan* takes an 
optional transducer, and an optional exception-handler (like chan). A 
promise channel can take exactly one value that consumers will receive. 
Once full, puts complete but val is dropped (no transfer).
Consumers will block until either a value is placed in the channel or the 
channel is closed (and nil will be delivered). 

2) *offer!* and *poll!* are two new non-blocking functions available on 
channels.

offer! puts a val into a channel if it can do so immediately and will never 
block. Returns true if offer succeeds.
poll! takes a val from a channel if it can do so immediately and will never 
block. Return a value if successful, nil otherwise.

All changes:
