近日，甲骨文公司宣布，官方版Java JDK 7 U4已经发布，提供了对Mac OS X 的支持，而之前Mac的JDK一直是由苹果提供的，随之而来的还有JavaFX的SDK，由于苹果取消了默认状况下OS X Lion及以上版本的Java支持，因此，甲骨文需要自行发布相关软件。
此次放出的JavaFX SDK提供了配套的开发工具和文档，主要丰富了客户应用程序平台，用以帮助开发者在JavaFX平台开发相关应用。此客户应用程序平台中包含首次应用于苹果产品的Java开发套件（JDK，Java Development Kit）和Java FX软件开发套件（Java FX Software Development Kit）。最近新升级的Java垃圾收集器（Java garbage collection）和Java虚拟机（Java Virtual Machine）都反馈良好。
同时，与近日发布的JavaFX 2.1版本修复了之前版本中的一些bug，为Windows平台提供了JavaFX运行时，并且添加了许多新功能，主要内容如下：
- 新增了对Media H.264格式和AAC（高级音频编码）格式的支持。
- 新增了对Mac OS X平台的支持。但只能开发桌面应用，暂不支持开发Web应用。
- 新增了对LCD文本的支持。
- 提升了UI性能，新增Combo Box、Stacked Chart组件和application-wide菜单工具栏。
- 在Web视图中新增Java方法调用JavaScript的支持。
此外，开发者需要注意的是，只有在Windows平台上才可以同时安装JavaFX SDK和JavaFX运行时。不过，安装了JDK 7 update 4的Windows和Mac OS X平台的开发者都可以使用JavaFX SDK。
