更新Ghost到3.x.x

上次升级还是去年9月，时隔一年多了。虽然也已经没有什么真实吸引我的新功能，但每年例行的升级还是会做一下。新版本似乎已经支持了自定义路由，恰恰是我从wordpress转到ghost时最需要的功能，不过后来还是通过nginx的映射解决了，感觉现在也没啥动力再去修改配置。毫无疑问ghost的管理能力一直在加强，很多散落的静态页面也能更有效的管控起来。

有了ghost-cli，更新还是非常顺利和便捷，有命令行辅助，除了遇上一些国内下载的问题，还有就是几乎忘记了运行ghost的用户名密码外，过程平滑。当然，从2.x.x更新到3.1.1，大版本升级导致主题还是有些兼容工作要做，不过照着提示信息也能在短时间内修正好。

主题一些helper有更名，感觉比原来要更合理，从@blog变更为@site，也看的出，ghost的格局发生了质的变化。通过gscan.ghost.org能快速定位到主题内的问题，改完验证上传启用一气呵成。

更新后到后台看了下，设计风格并无二致，功能更加合理，特别时管理tag的能力强好多，信息展示和操作，还有自定义页面的能力，都好用不少。不过比起当初编写页面的改进，这些辅助功能的进化虽然也很惊艳，但毕竟没有Post页常用。很多新特性还在体验中，总之就是，好用！

PS：习惯性的想用pm2重启ghost，发现列表里空空如也，想了老半天才想起来要用ghost-cli操作...
