Golang 1.20: What is new?

What is new in Golang 1.20? Compared to the 1.19 release there are no major changes to the language but rather additions to the runtime, libraries and toolchain. The are lot of features but there eight I want to call out:

■ Go subcommands -C to change directory
■ Skip pattern support for generate and test
■ Code coverage for running applications
■ vet incorrect times
■ Wrapping multiple errors
■ archive/tar and archive/zip security changes
■ context's new WithCancelCause
■ time's new layout constants and compare

Thank you. I need to learn C# for my job, but I want to find time for much more enjoyable language, as Go for example.

There is a typo in readme file in 4:04, it should be "mkdir -p" instead of "mkdir -o".
Thanks

The context.WithCancelCause was definitely QoL feature.

This will make it easier to know which part of the code cancels the context by giving appropriate message that attaches to the context itself, rather than using an additional var / chan to store the error / cancellation message . IMO its more verbose & concise that way

Thank you for posting - Go keeps aging like wine!

I'm getting into nvim and would like to know how you got nvim tree to toggle in the center instead of a sidebar. Do you mind sharing your nvim config?

what is the best way to update? I just uninstall previous version and install the latest am I doing it right?

[viktor__]

error wrapping is the most useful feature of the release.

Beware of v1.20, lint is broken, resulting in panic. Issues have been raised already, so I’m expecting/hoping for a new release in the non too distant future.
