(This is a new PR identical to #292 (rebased to current master). I messed up and the other got closed and reopen button was disabled... Sorry!)

They don't provide a convenient format unfortunately, and my parsing might not be exhaustive.

It's also not very accurate when all you have to go by is "1 year [ago]".

But it's certainly better than nothing and seems to work well enough.

“the walrus operator” := was introduced in https://docs.python.org/3/whatsnew/3.8.html

We currently support Python 3.7.0 as our minimum in qBittorrent v4.6.x / v5.0.xbranches.
This is being raised to 3.9.0 in v5.1.x

@Chocobo1 Thoughts?

1. Should we ignore CI failure
2. Come up with an alternative
3. Implement/backport 3.9.0 requirement to v5.0.x branch which brings support for Published on date.

I noticed the CI failure too and I was working on an alternative as you were writing your comment!

The walrus is very useful, it wasn't easy to find an alternate way that is readable and yet not 200 lines.

If either of you have better ideas, by all means, I'm not a python expert :)

We currently support Python 3.7.0 as our minimum in qBittorrent v4.6.x / v5.0.xbranches.

The plugins should maintain compatibility with Python 3.7.0. A lot of people are still on qbt 4.6.x (or even 4.5.x). It would not be nice if an update makes the plugin unusable.
