Getting people on the same page for a project can be tough. It requires managing a ton of opinions and suggestions. The last thing you should have to worry about is making sure your team is literally working on the same document. That’s why we built our powerful real-time editing tools to help with this—Google Docs, Sheets and Slides—so that teams can work together at the same time, using the most up-to-date version.

Today, we're introducing new updates to better help with "version control," to customize tools for your workflows, and to help teams locate information when they need it.

Track changes, make progress

It can take dozens of edits to make a document just right—especially a legal agreement, project proposal or research paper. These new updates in Docs let you more easily track your team’s changes. Now, your team can:

1. Name versions of a Doc, Sheet or Slide on the web.
Being able to assign custom names to versions of your document is a great way to keep a historical record of your team's progress. It's also helpful for communicating when a document is actually final. You can organize and track your team’s changes in one place under “Version history” (formerly known as “Revision history”) on the web. Select File > Version history > Name current version. For even quicker recall, there’s an option to select “Only show named versions” in Docs, Sheets or Slides.

2. Preview “clean versions” of Docs on the web to see what your Doc looks like without comments or suggested edits.
Select Tools > Review suggested edits > Preview accept all OR Preview reject all.

3. Accept or reject all edit suggestions at once in your Doc so your team doesn’t have to review every single punctuation mark or formatting update.
Select Tools > Review suggested edits > Accept all OR Reject all.

4. Suggest changes in a Doc from an Android, iPhone or iPad device.
Click the three dots menu in the top right of your Doc screen to suggest edits on the go. Turn on the “Suggest changes” toggle and start typing in “suggestion mode.”

5. Compare documents and review redlines instantly with Litera Change-Pro or Workshare Add-ons in Docs. 


Here’s a quick way to preview and accept all changes (or reject them) and name versions of your document.
