list below.

compatibility of JRuby 9.3: @ahorek, @ccutrer, @evaniainbrooks,

Ruby Compatibility
Altering the visibility of an included module method no longer changes
what super method gets called. (#7240, #7343, #7344, #7356)
Thread termination at shutdown is more robust and visits all non-main
threads. (#7351)
Standard Library
csv has been updated to 3.2.5 to pick up a fix that eliminates fiber
use for simple parse_line calls. (#7346, #7348)
psych has been updated to 3.3.3 to address CVE-2022-25857, an
element-nesting DoS. (#7342)
Experimental Features
Fibers can now be configured to use OpenJDK Project Loom’s virtual
threads, which are lightweight and do not consume a native platform thread.
Virtual threads make it possible for JRuby applications to create thousands
of concurrently-executing fibers. Enable this feature on Java 19 using the
JVM flag --enable-preview. (#7328)
