I like to update any classes automatically. Mostly if you update with Composer you will fail with incompatibility.
I use the way to download a zip but this is with many zips a Long time.
With the VCS you download sometimes any Version of the last 10 years and any Change during that period, this will be a Long downloading.
I am looking for a Long time to get an automated
updating and sometimes it will be nice if you could choose the Versions for download, but I never found a solution.
