Here's a short list of the changes to look forward to for #golang 1.17, to start landing once the merge window opens in a few weeks.

Don't get confused with 1.16, releasing next month. 1.17 will come out in seven months.

Each change with a link, so you…

If @mdempsky finishes this (very likely) and Go 1.17 ships August 29th (might!) then it'll be exactly 10 years since I filed that wishlist compiler issue. 😂🎉🎂 https://t.co/sgIhhUV8WF

Turns out you can reduce the memory usage of a #golang by ~1.4MiB (on 64bit) by simply calling this at the beginning of your main: runtime.MemProfileRate = 0

Cool stuff: buffer pool in #golang based on databases.

Also a neat part: CLOCK Replacement algorithm (read as better LRU, LFU policy)(however better can be argued :)

Thank you twitter.com/brunocalza !

I have just published a proposal to add fuzz testing support to Go, with the goal of making this an experimental feature for 1.17. @jayconrod and I have been working hard on this for a while, and are excited for this next big step! 🎉 https://t.co/reN4ZiHi2Z

Are you missing static variables ever since you switched from C(++) to #golang? Get them back with this one weird trick! https://t.co/GmUPBK41ln

Go compiler and runtime meeting notes (https://github.com/golang/go/issues/43930)

> We discussed how to address amd64 per-architecture optimizations. Haswell specific optimizations have shown large improvements in certain workloads, and it might be worth providing for these wins. Discussion will likely continue.

Dear @golang developers, if you're bumping your project to use the new Go1.16 packages, **PLEASE** gatekeep them behind build tags so you don't break projects importing them with older versions. // +build go1.16 // +build !go1.16 Both work to make this happen…

Register-based calling convention for #golang functions is alive. Which is super great! Fingers crossed that it will land in Go 1.17 this ~August.

The Ryu algorithm for fast float64->decimal conversion.

Almost 5 years later it's merged, @dvyukov you should be happy, right? :D

Hope it will land in #golang 1.17 this August (or so) https://github.com/golang/go/issues/15672

Special thanks to @oudomphe CC: @ulfjack (Ryu author) and @calebspare
