Acumen 1.3.5 for Magento Community Edition 126.96.36.199 is available now. This was a pure compatibility release focused on stability and staying in line with the latest Magento code. Full release info is on the changelog.
Magento 188.8.131.52 included modifications in over 1600 files. As always, the entire changeset was evaluated to make sure nothing slips through the cracks. 84 files were updated in Acumen to maintain compatibility. It took 15.88 hours to properly diff, merge, test, and package this release.
Core compatibility is taken very seriously, and Acumen has never missed a Magento release (in over 3.5 years).
