perl-5.12.4 是 5.12 系列的维护版本,仅更改了 200 行(请参阅 http://search.cpan.org/dist/perl-5.12.4/pod/perl5124delta.pod),只是修复了一些错误,并确保 5.12 可以正常工作以Ubuntu为例。
5.14.1 是 5.14 系列中的最新版本。它很现代,很闪亮,这就是您想要的!
perl-5.12.4 is a maintenance version of the 5.12 line, it's only 200 lines of changes (see http://search.cpan.org/dist/perl-5.12.4/pod/perl5124delta.pod), just a couple of bug fixes, and making sure that 5.12 can work on Ubuntu for example.
5.14.1 is the latest version in the 5.14 line. It's modern, it's shiny, this is the one you want!
这不是第一次在新版本发布后发布维护版本
当 Perl 开发人员正在开发一个版本时(当前为 5.16) ,他们仍然维持之前的两个版本(目前是5.12和5.14)。
不过,维护版本中的更改非常有限。对于初学者来说,没有添加任何新功能。主要更新仅包括:
这意味着 5.12.4 将不会具有 5.14.0 中添加的新功能,并且也不会修复大多数错误。关键是要尽可能安全地获得关键修复。
This is not the first time there has been maintenance releases after a new version has been released
When the developers of Perl are working on one version (currently 5.16), they still maintain the previous two versions (currently 5.12 and 5.14).
The changes that go into maintenance releases are very limited, though. No new features are added, for starters. Primarily, the updates will only include:
That means 5.12.4 will not have the new features that were added to 5.14.0, and it won't have most bug fixes either. The point is to make it as safe as possible to get critical fixes.
它就像服务包:Perl 语言版本 5.12 的维护版本 4 在语言级别 5.14 的版本 1 之后发布。继续前进,公民,这里没什么可看的。
It's like service packs: Maintenance release 4 of Perl language version 5.12 came out after release 1 of language level 5.14. Move on, citizen, nothing to see here.
旧版本的 Perl 获得维护版本。例如,Perl 1.0.16 是在 Perl 5.6.2 之后发布的。

Older versions of perl get maintenance releases. For instance, Perl 1.0.16 was released after perl 5.6.2.
