The goroutine leak detector will become generally available in Go 1.27. But did you know you can also use synctest (Go 1.25+) to catch goroutine leaks in tests? See how the two approaches compare: antonz.org/detecting-gorouti…

My Go Concurrency book is now available on Amazon: amazon.com/dp/B0H94S2G4K And, of course, it's still free to read on my website: antonz.org/go-concurrency With interactive examples!

Over the past two years, I've published interactive tours for five Go releases, from 1.22 to 1.26. I know some of you have read them, and I've received a lot of kind words from you (even some core Go team members reached out) — thank you so much for that! Unfortunately, at some point, writing these tours stopped being fun and started to feel like a part-time job. I'm not really excited about that, so I've decided to stop. I still like Go (well, most of it). I read a lot of Go code, I write some Go code, and I write Solod code, which is also Go 🙂 (Solod is a systems language with Go syntax and a Go-like stdlib). I'm still pretty close to the language and will probably continue to write about it. But the interactive tours story is over.
