How to upgrade OSclass from 3.9.0 and should I even upgrade?

Hello all!

My (production) site is running on OsClass 3.9.0. I see that a lot of upgrades were made during the last time I checked.

I am wondering if I should upgrade to the newer version.

Is the version from the link stable enough to run the production site?

What is the best practice to upgrade? Just download new files and upload to the server (override old files).

Thanks in advance.

Best regards. Luka.

Develop branch is for development you shouldn’t upgrade your current installation to this tree.
Latest release can be found at this link

BTW before 4.x.x release, in any upgrade you new need to upload those files to your server like you said.
