Go 1.13 Released — Hurrah, a new version of Go! The big news for this release is the go commands will use Google’s module mirror and checksum database to grab modules (more on this below). TLS 1.3 support is also now enabled by default, along with numerous other things covered in the release notes. Alternatively, this slidedeck is also another neat way to tour the new features.

Go’s Official Module Mirror and Checksum Database Launched — The Go team have been working on a module mirror, index, and checksum database in order to improve performance, resiliency (as otherwise if dependencies disappear at their original sources, you’ll have trouble), and security when using third party modules. It’s used by default by Go 1.13 (above).
