JRuby 10.0.3.0

--- layout: post title: JRuby 10.0.3.0 Released --- The JRuby community is pleased to announce the release of JRuby 10.0.3.0. * Homepage: [https://www.jruby.org/](https://www.jruby.org/) * Download: [https://www.jruby.org/download](https://www.jruby.org/download) JRuby 10.0.3.x targets Ruby 3.4 compatibility. Thank you to our contributors this release, you help keep JRuby moving forward! @mrnoname1000, @ngr-ilmarh, @Earlopain, @philr, @jotamartos, @kares, @aleksandrs-ledovskis, @trinistr, @katafrakt, @chadlwilson, @khasinski, @evaniainbrooks Compatibility ------------- * JRuby now reports `RbConfig::CONFIG['arch']` without a version number, as `universal-java`. This allows using different JDK versions without triggering RubyGems missing extension warnings for installed gems. The host Java version is still available as `RbConfig::CONFIG['arch_version']`. [#9107] Standard Library ---------------- * The non-gem standard library is upgraded to Ruby 3.4.5 [#8967] * rexml is updated to 3.4.4 to address CVE-2025-58767. [#9011] * syslog is moved to a default gem at version 0.4.0. The syslog gem now includes JRuby support. [#9109], [ruby/syslog#1](https://github.com/ruby/syslog/1) * strscan is updated to 3.1.7. [#9159] Documentation ------------- * Ruby ri documentation for core and standard library are now included in the release distribution.
