Seeking for a stable v3.0 package

[tonymiao2012]

Dear developer,

I am a LABjs user. Since I noticed that the 2.0 version of LABjs hadn't been activated for more than 3 years, is it possible to fetch a stable current release to replace the v2.0 one?

Recently I am doing optimization for a project and this project is using old v2.0 LABjs. I wonder if I replace it with latest one, there will be a huge performance improvement. If possible, please offer some technical supports. You are greatly appreciated.

Best,
Tony
