Nice new compiler flags!!! Thank you for the video!

LTS is a good way to go, java/c# and others are doing LTS, and they also have features that experimental. it is a good way forward, now the community should help on the tooling side, and education on things like meta programming and advance features of scala should be made more accessible to scala users as well as their uses, so knowing when to use and not to use an advance feature is also important.

Yes LTS relese is needed. AND FORWARD compatibility and source forward compatibility will be ASSURED! Mainterners of big libraries have a lot of problems take for example going from scala 2.11 macros to scala 3 macros is a nightmare. And some projects are abadomed. It would be so nice to have forward compatibility so we can use reuse OLD stuff and we don't throw away work invested in library makers! Take for example scala library autowire it stuck on scala 2.13... no scala 3 version. So imagine now lots of work invested into 3.x and when 3.8 comes out... everything needs to recompile re publish.. this throws people away. I think scala is good enough for now. They need to freeze new features and so more on tooling. and compiler optimizations. And let the industry to force them up new features that we really need.

Oh, I can hardly wait for this LTS version.
I have guessed that 3.3 would be released in this weekend, but what came out is 3.3-RC6
