Now lab to 6.5

After alert some files in gitlab, the upgrade process become not such an easy and happy job. Every new version come out, dozens of files need to merge manually to upgrade gitlab successfully. So, after hours of mental struggle, I finally decide to upgrade it. To be honest, the process is not as terrible as I thought it would be. But still, DOZENS of files to edit…… Fuck ruby!..

And now the update process has been finished. All things seem to be good. If anything went south, please email me~
