Laut https://mail.openjdk.java.net/pipermail/jdk-dev/2019-August/003250.html:

Per the JDK 13 schedule [1], we are now in the Release Candidate phase.
The stabilization repository, jdk/jdk13, is open for P1 bug fixes per
the JDK Release Process (JEP 3) [2].  All changes require approval via
the Fix-Request Process [3].

If you’re responsible for any of the bugs on the RC candidate-bug list
[4] then please see JEP 3 for guidance on how to handle them.

We’ll tag the first Release Candidate build shortly.
