Today, we're happy to announce the release of a new and improved ability to track changes on Authorea. Based on git, the most sophisticated version control system available today, researchers using Authorea can now see word by word edits from co-authors or a per-day summary of changes made. Because the version control system is built into the document creation process and not simply added on, like track changes used in Word or Google Docs, the full life cycle of a paper will be available. Such functionality will make collaborating and editing even easier amongst researchers on Authorea, accelerating the time it takes to report your findings and saving your inbox from the deluge of emails with different versions of the same paper that is typical of collaboration in other editors, like Word.
