This release is based on Go 1.20's gofmt, and requires Go 1.19 or later.
The biggest change in this release is that we now vendor copies of the packages go/format, go/printer, and go/doc/comment on top of cmd/gofmt itself. This allows for each gofumpt release to format code in exactly the same way no matter what Go version is used to build it, as Go versions can change those three packages in ways that alter formatting behavior.
This vendoring adds a small amount of duplication when using the mvdan.cc/gofumpt/format library, but it's the only way to make gofumpt versions consistent in their behavior and formatting, just like gofmt.
The jump to Go 1.20's go/printer should also bring a small performance improvement, as we contributed patches to make printing about 25% faster:
The following changes are included as well:
