Updated for Magento 22.214.171.124 compatibility.
Acumen 1.3.8 for Magento Community 126.96.36.199 is available now. It’s a pure compatibility release. I shelved backporting the new configurable swatches feature (for now).
Full release info is on the changelog.
Why no swatches
Magento (stupidly) split where frontend updates are applied:
base/default (core updates) vs
rwd/default (new features). Forcing sites to backport features across frontend packages creates fragmentation in the fallback hierarchy.
You’ll need to track/diff/merge two packages instead one by backporting. Effectively Magento skipped a fraction of work, and complicated maintenance for existing sites that want swatches. Not smart — I hope not a precedent.
Nevertheless, the option to backport exists. Swatches aren’t a priority in Acumen’s immediate roadmap so I shelved it temporarily.
