 Change Log
 ==========
 
-Version 1.5.7 - 
------------------
+Version 1.5.7 - October, 2012
+-----------------------------
+- NOTE: This is the last release of pyparsing that will try to 
+  maintain compatibility with Python versions < 2.6. The next
+  release of pyparsing will be version 1.6.0, using new Python
+  syntax that will not be compatible for Python version 2.5 or
+  older.
+
 - An awesome new example is included in this release, submitted
   by Luca DellOlio, for parsing ANTLR grammar definitions, nice
   work Luca!
@@ -24,10 +30,20 @@ Version 1.5.7 -
   storing the contents of a Forward(). '<<=' does not have the same
   operator precedence problems that '<<' does.
 
+- 'operatorPrecedence' is being renamed 'infixNotation' as a better
+  description of what this helper function creates. 'operatorPrecedence'
+  is deprecated, and will be dropped entirely in a future release.
+
+- Added optional arguments lpar and rpar to operatorPrecedence, so that 
+  expressions that use it can override the default suppression of the
+  grouping characters.
+
 - Added support for using single argument builtin functions as parse 
   actions.  Now you can write 'expr.setParseAction(len)' and get back
   the length of the list of matched tokens.  Supported builtins are:
   sum, len, sorted, reversed, list, tuple, set, any, all, min, and max.
+  A script demonstrating this feature is included in the examples
+  directory.
 
 - Improved linking in generated docs, proposed on the pyparsing wiki
