Microsoft revealed plans to release a new Long-Term Servicing Channel (LTSC) release of Microsoft Office for Windows and Mac devices today.

Microsoft Office 2021 will be the successor of Office 2019, and supported for five years from the day of its official release. Office 2019 and the upcoming Office 2021 are single-device products that are purchased with a one-time payment.

The new version of Office will introduce new features and improvements in the application. Office LTSC is feature-locked when it is released; Microsoft will release security and bug-fix updates but the application suite won’t receive constant feature updates like Windows 10 or Microsoft 365 after its release.

New Office LTSC features will include accessibility improvements, capabilities like Dynamic Arrays and XLOOKUP in Excel, dark mode support across multiple apps, and performance improvements across Word, Excel, Outlook, and PowerPoint.

The new Office ships with Microsoft Teams and not Skype for Business clients. The latter is available as a standalone download on Microsoft’s Download Center website.
