IntelliJ IDEA 5.1 發布了。
新版本，主要做了以下提升：更好的支持i18n，更好地支持插件開發，提升對JS和AJAX的支持, 開發了新的jsp debug模塊等等。
Enhanced i18n support
New intention actions and quick fixes for internationalizing strings, excluding string literals from internationalization, formatting properties and messages, together with auto-detection of resource bundles, smart editing of .properties files and other features appeared in 5.0 release, help developers to quickly localize applications keeping resources in a consistent state.
New JSP debugging support
Now IntelliJ IDEA allows for configuration of source-level JSP debugging when remotely connected to IBM WebSphere 5.1 or later.
More support for plug-in developers
New actions for auto-creating new application, module, and project components, together with new inspections for validating the consistency of plug-in descriptors, make it easier than ever to begin creating custom plug-ins.
因爲更好的支持了i18n,JetBrains 開發了IntelliJ IDEA 5.1的Japanese localization。5.0的用戶也可以免費升級。
