There is a release notes document here: https://struts.apache.org/docs/version-notes-25.html .这里有一个发行说明文档： https : //struts.apache.org/docs/version-notes-25.html 。 It contains the whole changelog, and it also references the fixed tickets.它包含整个变更日志，并且还引用了固定票证。

The 2.5.x series introduced some breaking changes, so the development is now branching, as 2.3.x is still supported. 2.5.x 系列引入了一些突破性的变化，所以现在开发分支，因为 2.3.x 仍然支持。 Basically they backport some changes to 2.3.x without breaking things.基本上，他们将一些更改向后移植到 2.3.x，而不会破坏任何东西。
