EDIT: I see now that this is likely unrelated to the next gen images. Sorry!
After this release our build was broken by the new circleci/ruby:2.5.7-node-browsers (sha256: fa5f52752167d32cc46e96ee99fde09693882928dcb006afd549e5d909d083cd). Pinning the image to the previous sha (sha256:36657bcdac99ec4c751cdf6d28d5f7e960f614a43bf2ba4e0fcbf1ee83be2bad) resolves the issue. Is there a changelog available somewhere that details the differences in how the new base image compares to the previous images?
Thanks in advance!
