Office 365 subscribers always have the latest version of Microsoft Office — currently Office 2016. They also get more frequent software updates than those who have purchased Office 2016 without a subscription, which means subscribers have access to the latest features, security patches and bug fixes. But it can be hard to keep track of the changes in each update and know when they’re available. We’re doing this for you, so you don’t have to.

Following are key updates to Office 365 for Windows since Office 2016 was released in September 2015 — all the 2017 updates and the most important ones from 2016 and late 2015, with the latest releases shown first. We’ll add info about new updates as they’re rolled out.

Note: This story covers updates released to regular Office 365 for Windows subscribers. If you’re a member of Microsoft’s Office Insider preview program or want to get a sneak peek at upcoming features, see the company’s “What’s new for Office Insiders” page.
