The fact that someone, for example, discovers something about Windows 98 doesn’t mean it can’t be published just because it’s something from the past.

Someone discovered something and made it public; they say Android 15 might have it. (It might have it.) The news was published today, but it doesn’t say it was discovered today. If you already knew that, then start a blog and publish it as news, because it’s something that wasn’t known before. Besides, even today, information and features of past technologies are still being discovered.
