| 14 | ## Talks |
| 15 | |
| 16 | * [GopherCon 2017: Russ Cox - The Future of Go](https://www.youtube.com/watch?v=0Zbh_vmAKvk) |
| 17 | * [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) |
| 18 | |
| 19 | ## Scope |
| 20 | |
| 21 | From talk above: |
| 22 | |
| 23 | * "maybe three major changes" |
| 24 | * plus minor housekeep tasks |
| 25 | * TBD |
| 26 | |
| 27 | Examples of major changes: |

| Brad Fitzpatrick | 87c535f | 2018-05-24 11:59:45 -0700 | [diff] [blame] | 30 | * [generics](https://github.com/golang/go/issues/15292)? |
| 31 | * [simplified, improved error handling](https://github.com/golang/go/issues/21161)? |
| 32 | * ... |
| 33 | |
| 34 | Examples of housekeeping: |
| 35 | |
| 36 | * [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) |

| 38 | ## Compatibility |
| 39 | |
| 40 | We do not want to break the ecosystem. Go 1 and Go 2 code must be able to interoperate in programs with ease. |
| 41 | |
| 42 | ## Standard library |
| 43 | |
| 44 | 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. |
| 45 | |
| 46 | ## Roadmap |
| 47 | |
| 48 | TBD |
