1.9.0-alpha12 includes the following changes since 1.9.0-alpha11:
- spec performance has been improved for many use cases
- spec explain printer is now pluggable via the dynamic var clojure.spec/*explain-out*
which should be a function that takes an explain-data and prints to *out*

rather than IllegalArgumentException
- pprint prints maps with namespace literal syntax when *print-namespace-maps* is true
- CLJ-1988 - coll-of, every extended to conform sequences properly
- CLJ-2004 - multi-spec form was missing retag
- CLJ-2006 - fix old function name in docstring
- CLJ-2008 - omit macros from checkable-syms
- CLJ-2012 - fix ns spec on gen-class signatures to allow class names
- CLJ-1224 - record instances now cache hasheq and hashCode like maps
- CLJ-1673 - clojure.repl/dir-fn now works on namespace aliases
