1.2.2

• Bugfix: click extension throws exception on events when using client-side .webp rewrite.
• Bugfix: polyfill src string passed to old $async.js() (now $async() for both CSS and js).

For data-attr extension:

• added data-b global base path for lazy-loaded images.
• added data-zz multi config param (accepts JSON array with configurations)
• removed: || token based multi-config

data-zz multi config and data-b (base)

<script async src="/js/z.js" data-zz='["z","zb",{
    selector: '[data-src]'
}]' data-b="/base-path/"></script>

<img data-z="relative/path.jpg">
<!-- src: /base-path/relative/path.jpg -->
