JRuby update improves Ruby 1.9 support
The JRuby community has released version 1.6.5 of its Ruby implementation for the Java Virtual Machine. According to the developers, the update continues to improve compatibility with the 1.9.x branch of Ruby by addressing a number of encoding issues found in the previous release.
JRuby 1.6.5 also requires less memory for C extension support and updates Rubygems to version 1.8.9. Other changes include the addition of a USR2 Ruby thread dumper and .jrubyrc support for storing convenient execution options, as well as improvements to Java Maps and Fiber performance, and better support for JVM coroutines and zlib. Users running previous versions of JRuby are encouraged to upgrade to 1.6.5.
Further details about the update, including a list of fixes, can be found in the official release announcement. JRuby 1.6.5 is available to download from the project's site. Hosted on GitHub, JRuby source code is tri-licensed under the CPL (Common Public Licence), GPLv2 and LGPLv2.1.
