Clojure 1.6.0-alpha3 is now available.
Try it via
- Leiningen: [org.clojure/clojure "1.6.0-alpha3"]
Clojure 1.6.0-alpha3 has the following changes from 1.6.0-alpha2:
1) Reverted: CLJ-1125 (fix for permgen leak) based on the regression reported in CLJ-1299. A fix for this regression is in development and I expect it to be re-applied in a future alpha.
2) The following features are no longer marked "Alpha" in Clojure (woohoo!):
* Watches - add-watch, remove-watch 18 * Transients - transient, persistent!, conj!, assoc!, dissoc!, pop!, disj!
* Exception data - ex-info, ex-data
* Promises - promise, deliver
* Records - defrecord
* Types - deftype
* Pretty-print tables - print-table
3) Applied patches for:
* [CLJ-827](http://dev.clojure.org/jira/browse/CLJ-827) - New function: clojure.core/unsigned-bit-shift-right
* [CLJ-866](http://dev.clojure.org/jira/browse/CLJ-866) - New function: clojure.test/test-vars
* [CLJ-1102](http://dev.clojure.org/jira/browse/CLJ-1102) - Better handling of exceptions with empty stack traces.
* [CLJ-939](http://dev.clojure.org/jira/browse/CLJ-939) - Exceptions thrown in the top level ns form are reported without file or line number.
* [CLJ-858](http://dev.clojure.org/jira/browse/CLJ-858) - Improve speed of STM by removing System.currentTimeMillis.
* [CLJ-669](http://dev.clojure.org/jira/browse/CLJ-669) - clojure.java.io/do-copy: use java.nio for Files
* [CLJ-1105](http://dev.clojure.org/jira/browse/CLJ-1105) - clojure.walk now supports records.
* [CLJ-949](http://dev.clojure.org/jira/browse/CLJ-949) - Removed all unnecessary cases of sneakyThrow.
* [CLJ-1238](http://dev.clojure.org/jira/browse/CLJ-1238) - Allow EdnReader to read foo// (matches LispReader behavior).
* [CLJ-1264](http://dev.clojure.org/jira/browse/CLJ-1264) - Remove uses of _ as a var in the Java code (causes warning in Java 8).
* [CLJ-1222](http://dev.clojure.org/jira/browse/CLJ-1222) - Multiplication overflow issues around Long/MIN_VALUE
* [CLJ-1118](http://dev.clojure.org/jira/browse/CLJ-1118) - Inconsistent numeric comparison semantics between BigDecimals and other numerics
3) Full change log is updated as well:
Still on the plate are 16 tickets (I expect many but not all of those to make it in) and the hashing performance work (http://dev.clojure.org/display/design/Better+hashing). Once we reach "completion" we'll release an RC for final testing.

Thank you.
I’d like to take this opportunity to thank the Clojure/core team for the slow, measured pace of development and stability of Clojure. 1.6 looks like a safe, gentle upgrade from 1.5.1.
Ironically the biggest change for me in 1.6 is the new API stuff - I look forward to rewriting my cfmljure library to leverage the new API once it goes gold! 😊

Please be aware that we expect to make changes to the API package and class name in the next alpha based on a discussion today so you may want to wait for RC for that!

BTW (and I may be a little late here) - is there a plan to add keyword creation to the API? Keywords are a pretty common part of many Clojure APIs, it would be good to allow their creation without forcing people to use Keyword.intern().

IFn kw = API.var("clojure.core", "keyword");

... kw.invoke("str") ... // produces :str
That's what I do in cfmljure, just wrapped up in my own utility function.
