+0.7.0 (2012-04-18)
+------------------
+
+Big Changes:
+
+* Added ability to pass options to |PEG.buildParser|.
+* Implemented the |trackLineAndColumn| option for |PEG.buildParser| (together
+  with the "--track-line-and-column" command-line option). It makes the
+  generated parser track line and column during parsing. These are made
+  available inside actions and predicates as |line| and |column| variables.
+* Implemented the |cache| option for |PEG.buildParser| (together with the
+  "--cache" command-line option). This option enables/disables the results cache
+  in generated parsers, resulting in dramatic speedup when the cache is disabled
+  (the default now). The cost is breaking the linear parsing time guarantee.
+* The current parse position is visible inside actions and predicates as the
+  |offset| variable.
+* Exceptions thrown by the parser have |offset|, |expected| and |found|
+  properties containing machine-readable information about the parse failure
+  (based on a patch by Marcin Stefaniuk).
+* Semantic predicates have access to preceding labels. [GH-69]
+* Implemented case-insensitive literal and class matching. [GH-34]
+* Rewrote the code generator -- split some computations into separate passes and
+  based it on a proper templating system (Codie).
+* Rewrote variable handling in generated parsers in a stack-like fashion,
+  simplifying the code and making the parsers smaller and faster.
+* Adapted to Node.js 0.6.6+ (no longer supported in older versions).
+* Dropped support for IE < 8.
+* As a result of several optimizations, parsers generated by 0.7.0 are ~6.4
+  times faster and ~19% smaller than those generated by 0.6.2 (as reported by
+  /tools/impact).
+
+Small Changes:
+
+* Fixed reported error position when part of the input is not consumed. [GH-48]
+* Fixed incorrect disjunction operator in |computeErrorPosition| (original patch
+  by Wolfgang Kluge).
+* Fixed regexp for detecting command-line options in /bin/pegjs. [GH-51]
+* Generate more efficient code for empty literals (original patch by Wolfgang
+  Kluge).
+* Fixed comment typos (patches by Wolfgang Kluge and Jason Davies). [GH-59]
+* Fixed a typo in JavaScript example grammar. [GH-62]
+* Made copy & paste inclusion of the PEG.js library into another code easier by
+  changing how the library is exported.
+* Improved the copyright comment and the "Generated by..." header.
+* Replaced Jakefile with Makefile.
+* Added "make hint" task that checks all JavaScript files using JSHint and
+  resolved all issues it reported. All JavaScript files and also generated
+  parsers are JSHint-clean now.
+* Fixed output printed during test failures (expected value was being printed
+  instead of the actual one). Original patch by Wolfgang Kluge.
+* Added a /tools/impact script to measure speed and size impact of commits.
+* Various generated code improvements and fixes.
+* Various internal code improvements and fixes.
+* Improved README.md.
