Off the top of my head:
* Haskell language server solved the ide support problem
* Easy record access with . syntax (i.e. person.name to get a name off a person)
* A new {-# LANGUAGE GHC2021 #-} pragma that turns on a bunch of flags by default to write modern haskell
* GHCup to control installed haskell & tool versions
* Haskell foundation formed to support growing haskell
* A proposal* to work towards supporting dependent types was accepted
A lot more of course but it all points to making haskell more enjoyable to get into and use, and a good future ahead.
