I extracted a DIFF file from the patched PdfJs.js file for Share (as components/preview/PdfJs.js) and the original for Alfresco 7.0 - note that some changes are only due to my code QA setup with automatic JS linting. Unfortunately I cannot attach text-based files, so it'll have to be an inline code block:
