traccar v4.0 vs v4.6

Hi Anton, I am very grateful to you because you are very consistent in update the Traccar. I haven't followed the latest Traccar update for a long time. I still use traccar version 4.0. In your opinion, is the Traccar lighter version 4.0 or the latest version 4.6?

I recommend to always use latest version.

thank you Anton, from v4.0 to latest version no need update mysql database structure ?
