ESLint 0.6.0 released

We just pushed ESLint 0.6.0, which is a significant release with new features, new rules, and of course, some bug fixes.

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.

Rules

• Breaking: 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)

• New: no-restricted-modules (#791)
• New: no-inner-declarations (#587)
• Update: The default value for the vars option of no-unused-vars was changed to "all". This addresses the issue where some were unexpectedly seeing unused global variables missed. (#760)

• Update: no-extra-parens now doesn't flag IIFEs (#655)

CLI
