Tuesday, February 20 2024

The JRuby community is pleased to announce the release of JRuby

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.

Ruby Compatibility

  • IO#fcntl had inverted logic for setting O_NONBLOCK (setting it cleared the value, etc). #8081, #8090

Standard Library

  • strscan is updated to the 3.1.0 version #8086

Native Integration

  • The subsystem used for native calls has been updated to support RHEL/CentOS 7 and the Java 9+ Cleaner API. #8104 Note: Due to a mistake in the release process released yesterday only changed in version number. It was essentially with a new version.
