+## 0.0.5 - 2013-09-01
+Originally slated for August 1st I decided to push this release back one month
+to buy myself some extra time to polish features, resolve more bugs and
+procrastinate more. Besides numerous bug fixes and extra polish this release
+contains two big new features that I'd like to highlight:
+* support for parsing basic YARD tags
+* loading of externally defined constants/files from the local file system
+### YARD Support
+[YARD][yard] provides a set of tags that can aid in documenting your code. For
+example, `@param` is a tag used to document the type, name and description of a
+method parameter. Since Ruby has no form of type hinting you're often left to
+wonder what kind of objects a method can work with.
+In version 0.0.5 support for two tags was added:
+* `@param`
+* `@return`
+When ruby-lint finds methods documented using these tags it will use them to
+pull in information about the parameter types and return values. This greatly
+increases the accuracy of ruby-lint, given your code is documented. Consider
+the following example:
+ def multiply(value, multiplier)
+ return value * value
+ end
+If ruby-lint were to process the above code it would have no idea what kind of
+object `value` and `multiplier` are and thus wouldn't be able to much with the
+above code. When documenting the above method with the mentioned YARD tags
+ruby-lint *is* capable of doing this:
+ ##
+ # @param [Fixnum] value
+ # @param [Fixnum] multiplier
+ # @return [Fixnum]
+ #
+ def multiply(value, multiplier)
+ return value * value
+ end
+By parsing the YARD tags ruby-lint can now know what the parameter types are
+and what type of data the method returns. This in turn allows ruby-lint to
+perform full analysis on the arguments instead of being forced to ignore them
+### Loading External Files
+In previous versions ruby-lint had no way of loading external code that was not
+pre-defined using the built-in definitions (found in
+`lib/ruby-lint/definitions`). As a result a lot of false positives would be
+triggered when analysing complex projects (e.g. the typical Rails project).
+This has been addressed by introducing so called "file scanners" and "file
+loaders". In short, these scan for a set of constants used in a file and try to
+find the corresponding Ruby file that defines it (recursively). This greatly
+enhances the accuracy of analysis.
+Currently the algorithm for this is rather basic and can, especially in big
+projects, slow analysis down by quite a bit. This will be resolved in upcoming
+releases. Keep an eye on the following issues for more information:

+### Other Changes
+Besides the two features mentioned above various other changes have also been
+made, these are listed below.
+* Lots of bug fixes and cleanups, as you'd expect.
+* Constants (classes and modules) can now be referred by their name inside
+ themselves (e.g. "Foo" inside the class "Foo" refers to that class).
+* The text presenter now only shows filenames instead of the full file path,
+ reducing clutter.
+* Support for default global variables such as `$LOADED_FEATURES`
+* Support for methods such as `alias` and `alias_method`
+* Support for the `attr_*` family of methods
+* The test suite has been migrated from Bacon to RSpec
+* Support for keyword arguments.
+* Updated built-in Rails definitions to include more methods.
+* Debugging/benchmarking output for the analyze command.
+* The analysis class ConfusingVariables has been removed due to not being very
+ useful.
+* Various issues with method lookups inside blocks have been resolved.
+* Various internals have been cleaned up.
+* Improved error messages for calls to undefined methods.
