Google has rolled out a new schedule for ending support for Chrome Apps – packaged desktop applications built with HTML, CSS and JavaScript – in favour of Progressive Web Apps (PWAs) and other browser-based approaches such as Chrome Extensions.

The plans to cease supporting Chrome Apps are not new: In August 2016 the company said: "We will be removing support for packaged and hosted apps from Chrome on Windows, Mac, and Linux over the next two years."
