ESLint 0.6.0 released

Deprecation Notices

• The 0.6.x ESLint will be the last to support the deprecated JSON format for .eslintignore. This was deprecated in 0.5.1 and will be removed in 0.7.0. Please change your .eslintignore files to the new plain-text format. See #761.

Breaking Changes

• brace-style now disallows block statements where curlies are on the same line. While not strictly a breaking change, it is a significant enough change to warrant being called out in this way. (#758)
• Node 0.8.x is no longer officially supported as of 0.6.0. We will no longer accept or fix bugs for Node 0.8.x.
