Capitalists want money, and they usually do whatever makes money. In software, constant churn and superficial redesign seems to make more money than reliability, security, and core improvements. Be that as it may, Office 365/Teams are probably new since Office 97. Arguably it wasn't a Microsoft innovation per se and was a response to Google Docs/Slack/etc. but internet/cloud/web-based collaborative editing integrated with group chat, video conferencing, and document sharing are probably new features since Office 97 that are somewhat useful, even if they don't work particularly well.
