Open standards such as HTML5, WebGL, and WebAssembly have continually matured over the years and serve as viable alternatives for Flash content. Also, major browser vendors are integrating these open standards into their browsers and deprecating most other plug-ins (like Flash Player). See Flash Player EOL announcements from Apple, Facebook, Google, Microsoft and Mozilla.
多年来不断成熟的开放标准，如HTML5、WebGL和WebAssembly等，成为Flash内容的可行替代品。主要的浏览器供应商正在将这些开放标准进行集成，并反对大多数其他插件（如flashplayer）。请参阅苹果、Facebook、谷歌、微软和Mozilla发布的Flash Player EOL公告。
By providing more than three years’ advance notice, Adobe believes that there has been sufficient time for developers, designers, businesses, and other parties to migrate Flash content to new standards. The EOL timing was in coordination with some of the major browser vendors.
通过提前三年多发出通知，Adobe认为开发者、设计师、企业和其他各方有足够的时间将Flash内容迁移到新标准。EOL的时间安排与一些主要的浏览器供应商进行了协调。
