Google Plans Go 2

Golang programming community has started working on the next version of golang programming language, Go 2.

Yesterday at GopherCon 2017, Russ Cox announced the process of starting the next version of Google’s popular programming language Go, Go 2. Go (golang) has become one of the most popular programming languages recently.
Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.

Announced via a blog post:

A major difference between Go 1 and Go 2 is who is going to influence the design and how decisions are made. Go 1 was a small team effort with modest outside influence; Go 2 will be much more community-driven. After almost 10 years of exposure, we have learned a lot about the language and libraries that we didn’t know in the beginning, and that was only possible through feedback from the Go community.
In 2015 we introduced the proposal process to gather a specific kind of feedback: proposals for language and library changes. A committee composed of senior Go team members has been reviewing, categorizing, and deciding on incoming proposals on a regular basis. That has worked pretty well, but as part of that process we have ignored all proposals that are not backward-compatible, simply labeling them Go 2 instead. In 2017 we also stopped making any kind of incremental backward-compatible language changes, however small, in favor of a more comprehensive plan that takes the bigger picture of Go 2 into account.
At the time of writing, there are around 120 open issues labeled Go 2 proposal. Each of them proposes a significant library or language change, often one that does not satisfy the existing Go 1 compatibility guarantee. Ian Lance Taylor and I have been working through these proposals and categorized them (Go2Cleanup, NeedsDecision, etc.) to get an idea of what’s there and to make it easier to proceed with them. We also merged related proposals and closed the ones which seemed clearly out of the scope of Go, or were otherwise unactionable.
Ideas from the remaining proposals will likely influence Go 2’s libraries and languages. Two major themes have emerged early on: support for better error handling, and generics. Draft designs for these two areas have been published at this year’s GopherCon, and more exploration is needed.
