Bug Fixes:

• This release bundles a new version of JRuby - [1.7.23], which fixes a memory leak issue reported on Windows when using the file input ([#3754]).
• File Input: Properly release file handles for older files which allows users to delete them ([#31]).
• Clean up resource usage when Logstash is restarted with File input. Previously, this would cause Logstash to grab on to duplicate file handles ([#77]).
