The JRuby community is pleased to announce the release of JRuby 1.4.0 Homepage: [http://www.jruby.org/](http://www.jruby.org/) Download: [Downloads — JRuby.org](http://www.jruby.org/download) After three very helpful release candidates we have a final 1.4.0 release. This release ends a long release cycle in which we resolved a huge number of issues. The headline feature is a move to Ruby 1.8.7 support, in line with Rails’ own plans to make 1.8.7 the required minimum version of Ruby. We have also gotten more serious about out 1.9 support (–1.9). The bigger applications mostly just work at this point, but we still have a ways to go on 1.9 support. Please try your 1.9 code in JRuby and help us firm things up. 1.4.0 Highlights: - JRuby is now compatible with 1.8.7 patchlevel 174 - Windows Native Launcher - Solves many reported bugs with our old .bat scripts - New YAML parser Yecht (bug-for-bug compatible with Syck!) - Improved Java Integration Support - faster - new java\_method, java\_send, and java\_alias methods - Windows installer - New embedding framework - Java 6 scripting out of the box - New org.jruby.embed package to supersede JavaEmbedUtils - Many 1.9 mode (–1.9) fixes - updated stdlib to 1.9.2preview2 - Rubygems now working - Rails 2.3.3 simple apps working (2.3.4 has 1.9 bug) - rubygems 1.3.5 - Much better error reporting - shorter backtraces with less Java - Ruby-compatiable syntax error reporting - 307 bugs fixed since 1.3.1 We want to thank all the users who have been helping us to get a better release out. Special thanks to Hiro A., David C., and Roger P. for their recent activity in the project. We also want to welcome Yoko H. as a committer to the project. Her work and support of our embedding efforts has been great.

Hi list Is there a recommended way to deal with gem migration to the new release? I’ve been using jruby 1.3.0 and have a few gems installed. I copied the gem cache over but can’t seem to build from it. Thanks Steve. ---

What do you mean you can’t “build from it”? - Charlie
