New Release: 2.9.0

The JSHint team Sep 3rd, 2015

Note This release was revoked shortly following its publication. Please refer to the release notes for version 2.9.1 for more information (found in the project's CHANGELOG.md file and on the project's website).

This release was a long time in the making, but it may not be the most exciting version we've published. Most of the changes are internal refactorings that were necessary to properly fix bugs. And fix bugs we did! Special thanks go to Luke Page, the newest addition to the JSHint team. Luke is a maintainer of the Less CSS project, and he introduced himself to use by overhauling JSHint's variable tracking logic.

JSHint 3.0 is closer than ever. We're excited for the opportunity to break a few things in order to make real strides forward. In fact, the hardest part will be limiting ourselves (we don't want to make migrating to the new version onerous). If you have any ideas along these lines, please submit them on the project's issue tracker. We'll mark them with the label "Breaking Change", and as we decide what's definitely "in" for 3.0, we'll add them to the "v3.0.0" milestone.
