Go 1.21 release candidate is available.

It has some interesting changes in my opinion:

  • clear() for clearing maps
  • new slices package for common operations on slices
  • new maps package for cloning and comparing maps

And some somewhat interesting ones:

  • min/max function directly in the language without a package (could have easily been in math package, but then again, you can min/max strings with this?)
  • structured logging package

Some other optimizations and improvements.

What do you think?

Not easily while avoiding the allocation hit of variadic arguments. But funny that, after all these years waiting on parametric polymorphism to be able to add a generalized min/max, it ends up as a built-in anyway.
