The book is basically done for now. I will likely update it for Scala 3, but that's still a moving target, so I'll wait for the dust to settle before considering it.
I don't expect the code to need to change too much to support Scala 3: Scala 3 is likely going to be backwards compatible to a large degree, and the code you'll be writing in Hands-on Scala is pretty simple Scala that doesn't touch the more advanced features that might be affected by the upgrade
As far as I know, an employee who was illegally laid off by bilibili put part of the company's background code on GitHub to vent his anger.
And then GitHub has directionally shielded the keywords "bilibili" and "go-common",
But it can be bypassed by typing only one character less. there are still a lot of projects alive.
It is not yet known who leaked it.
Also for the reason.
You can find some reports here by using Translation software(If this report hasn't been deleted yet)。
BiliBili once made a statement on Weibo, but delete in a few minutes.

You could link to the hearsay, assuming it was online.
FWIW, the report you link in your other comment has a screenshot of a conversation where someone claims that the code was leaked by an intern from Nankai University who didn't know how to use git. [1] That they're identified by their university makes me suspect that it's a rumor (edit: making fun of the university), though.
