New versions of Microsoft Office aren't as big a deal as they used to be, thanks to the continuously updated (and continuously paid for) versions of the apps that come with a Microsoft 365 subscription. But for everyone else, there's still Office 2021, an upgrade to Office 2019 that's coming to both Windows and macOS on October 5, Microsoft announced today. Office 2021 will add the same features as the Office Long-Term Servicing Channel (or LTSC, catchy) release, which is available today.
