product lifecycle

The product lifecycle tag covers how software changes over time after release, including support limits, compatibility requirements, licensing, and end-of-life effects. Current coverage focuses on Microsoft Office 2019 for Mac and older Microsoft 365 apps running on unsupported Apple devices. A certificate expiration scheduled for July 13, 2026, may place affected applications into reduced functionality mode, allowing users to open and print documents while blocking editing, saving, and creation. This product lifecycle discussion highlights how support policies, device compatibility, and time-based licensing controls can change the practical capabilities of software that customers have already installed or purchased.
