JRuby 1.3.0RC1 搞定了一些与 Google App Engine (GAE/J) 有关的 issue。我们决定发布一个更“短”的版本，这样子对 GAE/J 感兴趣的用户就不需要抓版本库构建一遍 JRuby 了。 译注：版本库里 10000 多个文件！

JRuby 1.3.0RC1 is a release to fix some issues which prevented JRuby from working with Google App Engine (GAE/J).  We decided to put out a shorter release so that users interested in GAE/J could get going without needing to build JRuby from scratch.

亮点：

◆一些修改，使得 JRuby 在一些受限环境内（如 GAE/J）跑得更顺

◆访问 Java 原生数组大约快 10 倍

◆timeout.rb 现在快了约 40% [ 译注：这话说的…… 难不成指定 10 秒你当 6 秒？ ]

◆irb 现在工作在 1.9 模式了；另外也有一些杂七杂八的 1.9 相关的修正

◆集成 rubygems 和 rspec 分别升级到 1.3.2 和 1.2.6

◆修了 1.2.0 以来的 22 个 bug
