JRuby 9.3.x is compatible with Ruby 2.6.x and stays in sync with C Ruby. As always there is a mix of miscellaneous fixes so be sure to read the issue list below.
Thanks to our contributors this cycle for helping to improve stability and compatibility of JRuby 9.3: @ahorek, @ccutrer, @evaniainbrooks, @naveensrinivasan
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)
