Checking the bug mentioned, it was fixed in 2022.

So, I’m wondering how one would upgrade to scala 3, while keeping old version of libraries?

Keeping updated libraries is a good practice (even mandatory if you get audits like PCI-DSS).

That part puzzled me more than the rest.

The normal way.

So is changing one thing at a time, especially when it's a major change like a language version upgrade.

Scala 3 slowed us down?
