Someone mentioned elsewhere in the thread, it was updated because it depended on obsolete libraries. Presumably the new libraries made the new design more straightforward to implement than attempting to reproduce the existing one.

What, exactly, was "obsolete" about those libraries. Did the code stop executing? Were they written in languages whose compilers/interpreters stopped functioning? Or were there simply newer, shinier toys to play with?

Absolutely everything connected to the internet needs to be kept up to date for a simple reason. Security.

We're past the 90's when "the code stopped executing" was the only valid reason for an update :-)

If you think I'm joking, there are huge companies that have already declared Python2 as non-supported software, so if you have any software written in Python2 you have to either rewrite or stop using it.
