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
Oh yes, finally! https://tip.golang.org/ref/spec#Min_and_max
Curious to know if
slogwill 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!
@nickel Not boring release this time !
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.
Love the new built-ins. Also the addition of the slice and map packages are welcome.
I’m still experimenting with PGO, but in my current projects it sadly does not lead to performance gains. Looking forward to working with the feature more in-depth though.
