Upgrading lichess to scala3

Hi all,

These last 2 weeks I've been very busy migrating the bulk of the lichess source code to a new version of the scala langage.

No less than 44,000 lines of code have changed: https://github.com/lichess-org/lila/pull/11875/files

While it doesn't come with immediate new features, think of it as a foundation strengthening move, allowing for long-term maintenance ease, performance, and extensibility.

I think it's now ready to go live, and that's what I'm doing this morning. Expect perturbations as we discover new bugs and push new fixes.

Thanks for your understanding.

thanks thibault

nice
keep going lichess devs

Thank you so much Thibault!

Nice work Thibault! @thibault

Hi, I am a club chess player and coder, found lichess cool and want to help.

If I want to volunteer what kind of skills in coding should I learn? ( I am completely new to coding)

Thanks for this huge work !

Thank you so much Thibault!

Chess is like coding : you can improve and get better, reach the top 1% and still be amazed by other people's achievements... In chess i'll never get nowhere near Magnus. In coding I'm amazed by @thibault 's skills ! :-)
