GopherJS 1.12–1 is released

Today we are happy to announce the release of GopherJS 1.12–1. You can get it on GitHub as usual.

This release adds support for Go 1.12. The support for Go 1.12 means that GopherJS 1.12–1 requires Go 1.12 and no longer works with Go 1.11. It’s highly recommended to be using the latest version of Go and GopherJS, but if you cannot upgrade from Go 1.11 right away, you should continue to use GopherJS on the go1.11 branch.

Installation or upgrade steps remain the same as before. To get the latest official stable release of GopherJS, please follow the instructions in the README. You can confirm that you have the right version if gopherjs version prints GopherJS 1.12-1.

GopherJS 1.12–1 continues to support nearly everything of the Go language specification, including goroutines, channels, select statement. Please consult the package compatibility table to see which standard library packages are supported. Everything from the previous Go 1.11 version is still supported, as are many of the additions that are new to Go 1.12. If you run into any issues or discrepancies with what the compatibility table says, please report an issue.

Thank you to Hajime Hoshi and Paul Jolly who worked on Go 1.12 support, and all contributors who have helped with this release. It is greatly appreciated.
