Office 2021 will include similar features.ĭon’t expect any major UI changes here, either. Microsoft isn’t fully detailing all of the features and changes in Office 2021 just yet, but the Office LTSC (Long-Term Servicing Channel) variant will include things like dark mode support, accessibility improvements, and features like Dynamic Arrays and XLOOKUP in Excel. Office 2021 will be available later this year for both Windows and macOS, and similar to the previous Office 2019 release, it’s designed for those who don’t want to subscribe to the cloud-powered Microsoft 365 variants. Microsoft is announcing two new versions of Office today: a consumer Office 2021 version and Office LTSC for commercial customers.
