Hello World,

I'm pleased to announce version 1.0.12 of rJSmin.


About rJSmin
============

rJSmin is a javascript minifier written in python. The minifier is based
on the semantics of jsmin.c by Douglas Crockford.

The module is a re-implementation aiming for speed, so it can be used at
runtime (rather than during a preprocessing step). Usually it produces
the same results as the original jsmin.c. It differs in the following
ways:

- there is no error detection: unterminated string, regex and comment
  literals are treated as regular javascript code and minified as such.
- Control characters inside string and regex literals are left
  untouched; they are not converted to spaces (nor to \n)
- Newline characters are not allowed inside string and regex literals,
  except for line continuations in string literals (ECMA-5).
- "return /regex/" is recognized correctly.
- Line terminators after regex literals are handled more sensibly
- "+ +" and "- -" sequences are not collapsed to "++" or "--"
- Newlines before ! operators are removed more sensibly
- Comments starting with an exclamation mark ('!') can be kept optionally
- rJSmin does not handle streams, but only complete strings. (However,
  the module provides a "streamy" interface).


About Release 1.0.12
====================

- Reworked handling of comments starting with exclamation marks. The matcher
  should no longer get out of sync, even if they appear in the middle of 
  other matches

- Handle line terminators before and after regex literals more sensible
