When downloading sources for an arm cross-compiler I found that there are several versions of gcc in maintenance. Latest builds are v4.9.4, v5.4.0 and v6.2.0.
下载arm交叉编译器的源时,我发现维护中有几个版本的gcc。最新版本为v4.9.4,v5.4.0和v6.2.0。
Why is there a v4 that is more recent than the latest release of v5 and the first release of v6 and what are the major differences between these versions?
为什么v4比最新版本的v5和v6的第一个版本更新,这些版本之间的主要区别是什么?

The older versions receive bug fixes only, while new features are implemented in the newer versions. From https://gcc.gnu.org/releases.html:
旧版本仅接收错误修复,而新功能则在较新版本中实现。来自https://gcc.gnu.org/releases.html:
The table is sorted by date. Note that starting with version 3.3.4, we provide bug releases for older release branches for those users who require a very high degree of stability.
该表按日期排序。请注意,从版本3.3.4开始,我们为需要高度稳定性的用户提供旧版本分支的错误发布。

This is not really a c++ question.
这不是一个c ++问题。
Developers are actively working on all of those versions at the same time. If one of those versions needs a bug fix then it will be patched and updated.
开发人员正在积极地同时处理所有这些版本。如果其中一个版本需要修复错误,那么它将被修补和更新。

Versions 4, 5 & 6 have newer C++ features, for example, I think 5 has std++14 and 6 has std++1z (you can search google for the features in each standard)
版本4,5和6具有较新的C ++功能,例如,我认为5具有std ++ 14和6具有std ++ 1z(您可以在google中搜索每个标准中的功能)
