Thanks also to the community of JRuby users for trying out JRuby 9.4.0.0 and filing issues! We’re proud to include so many fixes in this update release and we couldn’t have done it without your bug reports.

Ruby Compatibility

• Several fixes to keyword arguments are included in this release. #7434, #7494, #7497, #7502, #7513, #7537, #7552, #7561, #7572, #7573, #7574, #7583, #7592, #7593
• Random has been fixed to work properly with SecureRandom, which was generating all zeros. #7586, #7597, #7607, #7617

Standard Library

• The Psych YAML library is updated to 5.1.0. This version switches the JRuby extension to SnakeYAML Engine, avoiding CVEs against the original SnakeYAML and updating YAML compatibility to specification version 1.2. #6365, #7570, #7626

Platform Support

• Final changes to support the LoongArch64 architecture have been merged in. #7518

Performance
