| title: Go2 status | |
| --- | |
| This page tracks the status of "Go 2". | |
| We are currently seeking feedback on potential designs for improved error handling, error values, and generics: | |
| - [Announcement of Go2 Draft Designs](https://go.dev/blog/go2draft) | |
| - [Go2 Error Handling, Generics, and Error Values](https://go.googlesource.com/proposal/+/master/design/go2draft.md) | |
| ## Bugs | |
| - [Open Go2 bugs](https://github.com/golang/go/issues?q=is%3Aissue+is%3Aopen+label%3AGo2) | |
| ## Talks | |
| - [GopherCon 2017: Russ Cox - The Future of Go](https://www.youtube.com/watch?v=0Zbh_vmAKvk) | |
| - [GopherCon Russia 2018: Brad Fitzpatrick - Go: Looking back and looking forward](https://www.youtube.com/watch?v=ZCB-g2B4Y5A) (Go2 stuff is at about 20 minutes in) | |
| - [Sydney Golang Meetup - Rob Pike - Go 2 Draft Specifications](https://www.youtube.com/watch?v=RIvL2ONhFBI) | |
| ## Scope | |
| From talk above: | |
| - "maybe three major changes" | |
| - plus minor housekeep tasks | |
| - TBD | |
| Examples of major changes: | |
| - [versioning](https://github.com/golang/go/issues/24301) | |
| - [generics](https://github.com/golang/go/issues/15292)? | |
| - [simplified, improved error handling](https://github.com/golang/go/issues/21161)? | |
| - ... | |
| Examples of housekeeping: | |
| - [Open Go2Cleanup bugs](https://github.com/golang/go/issues?q=is%3Aissue+is%3Aopen+label%3AGo2Cleanup) (please don't add this label to things without discussion) | |
| ## Compatibility | |
| We do not want to break the ecosystem. Go 1 and Go 2 code must be able to interoperate in programs with ease. | |
| ## Standard library | |
| The standard library would probably be versioned and permit out-of-cycle updates, but be included with Go releases. Maybe "encoding/foo" become shorthand for "golang.org/x/std/encoding/foo". TBD. Some package would probably get v2 major versions, but the v1 versions would be minimally maintained, at least for security. | |
| ## Roadmap | |
| TBD |
