mark节选了些改进（同时包含在上述两个版本中）：
Equinox 
Equinox OSGi 框架升级至 OSGi Core Release 5 (R5)  
p2 发布器：只要声明一个negation requirement（如 Rich Ajax Platform (RAP) ），可以在没有安装到eclipse IDE的情况下发布

Platform 
SWT浏览器可嵌入 XULRunner 10.0.x ，但不支持 XULRunner versions 4.x - 9.x 
ColorDialog支持调用 getRGBs()和setRGBs(RGB []) 时显示颜色选择器

运行配置（ launch configuration ）中，若你命名的配置名已存在，会显示冲突。

JDT 
 现在你可以在Project properties > Java Build Path > Compiler > Source 设置是否忽略警告/错误提示。

Preferences > Java > Compiler > Errors/Warnings > Null analysis 作了一些改进

当设置 Preferences > Java > Compiler > Errors/Warnings > Null analysis > Missing '@NonNullByDefault' annotation on package 为可用后，会作出警告提示，表示你没有指定某包、某类型等等。

Java > Editor 参数页中的enclosing brackets可设置高亮，并制定颜色。
