This version contains the following fixes:
Upgraded to ES Module based routines, documented how to do it and support for CDNs via direct reference. This is months of work poured into HAX itself and the elements surrounding it and this includes a lot of state management enhancements as well.
Fix for Issue #3025470 by bdragon, Fabianx: transaction callback + cache tags caching is broken
Fixed PHP 7.2 compatibility.
Initial alpha release for core Media integration.
