Changes since 6.x-2.6:

Bug fixes

The first full release of HAX from testing! Future releases will primarily be to front-end / bower installed assets.
The biggest enhancement to this is that it now implements the hax-app-store concept, meaning that you can define new integration methods directly through a drupal hook. It also comes with out of the box support for popular services like YouTube, Vimeo, Giphy and more!

Future releases will start to see HAX interfacing directly with Drupal's file and entity systems.

Backport of the D7 enhancements. Also naming at a point release to match

Add optional cURL support. From the README:

It is possible to use cURL to phone home instead of Drupal's built-in drupal_http_request() function. This is not recommended, but may be useful if, for example, you need to use an outbound proxy. The following shows the PHP cURL options that are available through the tag1quo module.
