Upgrade to JDK13 for ZGC?

[Sundara Mohan M]

Hi,
    I am using ZGC and trying to see if any bug fixes gone in to JDK13
other than "Uncommit memory feature".

1. Was "memory uncommit" is the only feature gone in to JDK13?
2. Is there a way to find all the bug fixed in JDK13 and categorize it by
ZGC, so in future i can do it myself.


TIA,
Sundar
