January 12th 2017. We're continuing our journey to make accessibility simpler (by advancing our understanding of the "platform"). Version 1.4.0 comes 4 months after the last feature release. We pushed about 50 commits in an effort to understand focus behavior in SVG, update the build systems and upgrade automated testing to modern browser versions.

The highlights of v1.4.0

• Improving utilities for convenient and safe .focus(), .blur() to properly support SVG content
• Improving identification of focusable status of SVG content
• Upgrading babel from version 5.x to 6.x, by providing AMD modules via UMD bundles
• Upgrading to eslint from version 2.x to 3.x, switching to (slightly customized) eslint-config-semistandard

The numbers of v1.4.0

• Test coverage remained at ~99%
• The library grew from ~22KB to ~23KB gzipped (~73KB to ~76KB minified)
