IMPORTANT: This release is reflecting JS behavior context added inside modifiers module, so updating of modifiers to 1.2 is required. We also fixed composer dependencies by adding modifiers_pack.info.yml file.
Issue #2977926 by Petr Illek, kyberman: Wrong config for custom radial gradient modifier
IMPORTANT: This release is adding proper JS behavior context instead of processing all modifications only once. We also added all current Drupal core media type mappings.
There is still a backward compatibility (where JS context is missing), but sites implementing custom JS modifiers should add context into their callbacks. Please check modifiers_pack module for examples.
