Hi, The first EA build for JavaFX 14 is available now from https://gluonhq.com/products/javafx/#ea and from maven central. In the past, I noticed EA-builds are downloaded often, and that's a great thing. I think that without the JavaFX 13 EA-builds and the feedback, the native buffering feature would not have made it into the 13 release.
Therefore, I really recommend developers to use JavaFX 14-ea+1 (and later) during daily development. (I do *not* recommend using it in production). Early feedback is crucial in fast release cycles. Thanks, - Johan
