Go 1.21 Release Candidate - The Go Programming Language
go.dev
Go 1.21 RC brings language improvements, new standard library packages, PGO GA, backward and forward compatibility in the toolchain and faster builds.

Go 1.21 RC released today. Some really interesting new additions. I’m pretty excited to see the map and slice package additions that contain a lot of generic methods. Will be nice not to have to maintain my own going forward.

    I am super excited for this release. I think varargs min/max() built-ins are my favorite feature. Closely followed by clear() and improved type-param inference

    Curious to know if slog will finally allow the community to settle on a standard logger. I’ve been using logr.Logr interface for a long time now with zap as the backend. Will be nice to at least replace zap with the slog as the underlying logging mechanism to remove at least one dependency.

    That was a good write up of the loop var issue, I had run into that only once and figured it was just a part of the learning curve I hadn’t hit yet. Glad to see it’s an area everyone agreed could improve!

      Yea there is some really interesting stuff in this release! Love the addition of generics in the packages. I feel like future Go releases will have a lot more of these nice generic utils in them to help clean up userland code.
