Open standards like HTML5, WebGL and WebAssembly now provide many of the capabilities and functionalities that plugins like Adobe-Flash™ used to provide. Adobe™ is planning to end-of-life Flash. Specifically, Adobe™ will stop updating and distributing the Flash Player at the end of 2020 and encourage content creators to migrate any existing Flash content to these new open formats.
