+### Big Changes
+
+  * Completely rewrote the code generator. Among other things, it allows
+    optimizing generated parsers for parsing speed or code size using the
+    `optimize` option of the `PEG.buildParser` method or the `--optimize`/`-o`
+    option on the command-line. All internal identifiers in generated code now
+    also have a `peg$` prefix to discourage their use and avoid conflicts.
+    [[#35](https://github.com/dmajda/pegjs/issues/35),
+    [#92](https://github.com/dmajda/pegjs/issues/92)]
+
+  * Completely redesigned error handling. Instead of returning `null` inside
+    actions to indicate match failure, new `expected` and `error` functions can
+    be called to trigger an error. Also, expectation inside the `SyntaxError`
+    exceptions are now structured to allow easier machine processing.
+    [[#198](https://github.com/dmajda/pegjs/issues/198)]
+
+  * Implemented a plugin API. The list of plugins to use can be specified using
+    the `plugins` option of the `PEG.buildParser` method or the `--plugin`
+    option on the command-line. Also implemented the `--extra-options` and
+    `--extra-options-file` command-line options, which are mainly useful to pass
+    additional options to plugins.
+    [[#106](https://github.com/dmajda/pegjs/issues/106)]
+
+  * Made `offset`, `line` and `column` functions, not variables. They are now
+    available in all parsers and return lazily-computed position data. Removed
+    now useless `trackLineAndColumn` option of the `PEG.buildParser` method and
+    the `--track-line-and-column` option on the command-line.
+
+  * Added a new `text` function. When called inside an action, it returns the
+    text matched by action's expression.
+    [[#131](https://github.com/dmajda/pegjs/issues/131)]
+
+  * Added a new `$` operator. It extracts matched strings from expressions.
+
+  * The `?` operator now returns `null` on unsuccessful match.
+
+  * Predicates now always return `undefined`.
+
+  * Replaced the `startRule` parameter of the `parse` method in generated
+    parsers with more generic `options` parameter. The start rule can now be
+    specified as the `startRule` option. The `options` parameter can be also
+    used to pass custom options to the parser because it is visible as the
+    `options` variable inside parser code.
+    [[#37](https://github.com/dmajda/pegjs/issues/37)]
+
+  * The list of allowed start rules of a generated parser now has to be
+    specified explicitly using the `allowedStartRules` option of the
+    `PEG.buildParser` method or the `--allowed-start-rule` option on the
+    command-line. This will make certain optimizations like rule inlining easier
+    in the future.
+
+  * Removed the `toSource` method of generated parsers and introduced a new
+    `output` option of the `PEG.buildParser` method. It allows callers to
+    specify whether they want to get back the parser object or its source code.
+
+  * The source code is now a valid npm package. This makes using development
+    versions easier.
+    [[#32](https://github.com/dmajda/pegjs/issues/32)]
+
+  * Generated parsers are now ~25% faster and ~62%/~3% smaller (when optimized
+    for size/speed) than those generated by 0.7.0.
+
+  * Requires Node.js 0.8.0+.
+
+### Small Changes
+
+  * `bin/pegjs` now outputs just the parser source if the value of the
+    `--export-var` option is empty. This makes embedding generated parsers into
+    other files easier.
+    [[#143](https://github.com/dmajda/pegjs/issues/143)]
+
+  * Changed the value of the `name` property of `PEG.GrammarError` instances
+    from “PEG.GrammarError” to just “GrammarError”. This better reflects the
+    fact that PEG.js can get required with different variable name than `PEG`.
+
+  * Setup prototype chain for `PEG.GrammarError` correctly.
+
+  * Setup prototype chain for `SyntaxError` in generated parsers correctly.
+
+  * Fixed error messages in certain cases with trailing input
+    [[#119](https://github.com/dmajda/pegjs/issues/119)]
+
+  * Fixed code generated for classes starting with `\^`.
+    [[#125](https://github.com/dmajda/pegjs/issues/125)]
+
+  * Fixed too eager proxy rules removal.
+    [[#137](https://github.com/dmajda/pegjs/issues/137)]
+
+  * Added a license to all vendored libraries.
+    [[#207](https://github.com/dmajda/pegjs/issues/207)]
+
+  * Converted the test suite from QUnit to Jasmine, cleaning it up on the way.
+
+  * Travis CI integration.
+
+  * Various internal code improvements and fixes.
+
+  * Various generated code improvements and fixes.
+
+  * Various example grammar improvements and fixes.
+
+  * Improved `README.md`.
+
+  * Converted `CHANGELOG` to Markdown.
