Anmol Sarna takes us through what’s new in Scala 2.13:
Last, but not the least, the team has invested heavily in compiler speedups during the 2.13 cycle which resulted in some major changes with respect to the compiler.
Compiler performance in 2.13 is 5-10% better compared to 2.12, thanks mainly to the new collections.
There are a lot of changes in this version. I wonder how long before Spark supports it fully.
