Minor release

• Fixes an issue with some PNG files not correctly getting deployed due to fingerprinting not picking up files in manifests/JSON files reliably and thus the wrong paths being queried
• Fixes a paths issue reading back JSON data for the articles as SW was trying to read back // paths from the cache.

Another big release.
