As a reminder, at Nim Conf back in October 2022 Andreas presented Nim 2.0 in this video https://www.youtube.com/watch?v=aDi50K_Id_k&list=PLxLdEZg8DR...

Hearing again I cannot chuckle when Araq says: Nim v1 is good at everything, Nim v2 is supposed to be better at everything.

Back then it was supposed to come out in 2022 and indeed a RC1 came out in Dec. In the blogpost for RC1 you find the desciption of all new features: https://nim-lang.org/blog/2022/12/21/version-20-rc.html

This longer time is because extra care is being taken into having a smooth transitions (for example important libraries have been tested to work on nim v2, e.g. we made sure nimib was working with v2 in early Feb: https://github.com/pietroppeter/nimib/releases/tag/v0.3.6)
