Doesn’t seem to be much less commits then previous releases, yet the bullet point list is much shorter. I guess that means a lot of work goes into polishing and fixing issues, getting ready for Scala 3?

Also, lately most highlighted work was wrt. metaprogramming, I expected more of that in this announcement too. Does it mean that the work on metaprogramming is pretty much done at this point too (except again for polishing and fixing potential issues)?

Anyway, thanks for the hard work, good job!

The commits related to metaprogramming mostly affected the internal parts of the implementation (lots of polishing). We didn’t do many (or any) changes that affect the user interface during this release, hence the blogspot metaprogramming part was short.
