Greetings!
JDK 19 is now in Rampdown Phase Two [1]. The overall feature set is
frozen. Per the JDK Release Process [2] we now turn our focus to P1 and
P2 bugs, which can be fixed with approval [3]. Late enhancements are
still possible, with approval, but the bar is now extraordinarily high [4].
Given the current state of affairs, it is a good time to start testing
your project(s) on JDK 20 Early-Access builds. To conclude, please make
sure to check the heads-up below, including the one covering JavaOne!

## Heads-up - JavaOne is back!
After a long hiatus, JavaOne is back! From October 17-20 in Las Vegas,
JavaOne will be jam-packed with hundreds of valuable and actionable
sessions directly from the experts: learning sessions, tutorials,
hands-on labs, lightning talks, panels, an unconference, BoF's, etc. The
full JavaOne content catalog will be released soon. In the meantime,
make sure to check https://inside.java/javaone/ for more updates.
And if you are planning to attend JavaOne, please ping me. I'd like to
meet you in person to chat over OpenJDK and the Quality Outreach
program. And the drinks will be on me!
## Heads-up - JavaFX Media enhancements survey
The JavaFX team is conducting a short survey [5] to gather input on
potential JavaFX Media enhancements.
The process is quite simple as the feedback will be collected via the
openjfx-dev [6] mailing list. So if you are using JavaFX, make sure to
raise your voice.
