Go 1.17 Released — Unfortunately, my brief vacation was.. poorly timed, given that a big Go release dropped just as it begun! If it has flown under your radar till now, though, here it is. Here are the full 1.17 release notes, but improvements and changes include:

• Compiler improvements yielding a ~5% performance gain. (Or a lot more, if you're lucky!)
• 64 bit ARM support on Windows.
• Pruned module graphs in Go 1.17 modules.
• unsafe.Add and unsafe.Slice

The Go Team

Tidying Up the Go Web Experience with go.dev — Back in 2019 the Go team unveiled go.dev which was intended to be a new central place for Go related information, although golang.org has lived on till now. The plan, however, is to move everything over to the new domain. This has been mildly controversial, however, as many people prefer the classical homepage.
