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.

    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.
