[`v0.5.0`](https://togithub.com/mvdan/gofumpt/blob/HEAD/CHANGELOG.md#v050---2023-04-09)

[Compare
Source](https://togithub.com/mvdan/gofumpt/compare/v0.4.0...v0.5.0)

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:

-   https://go.dev/cl/412557
-   https://go.dev/cl/424924

The following changes are included as well:

- Skip `testdata` dirs by default like we already do for `vendor` -
\[[#&#8203;260](https://togithub.com/mvdan/gofumpt/issues/260)]
- Avoid inserting newlines incorrectly in some func signatures -
\[[#&#8203;235](https://togithub.com/mvdan/gofumpt/issues/235)]
- Avoid joining some comments with the previous line -
\[[#&#8203;256](https://togithub.com/mvdan/gofumpt/issues/256)]
- Fix `gofumpt -version` for release archives -
\[[#&#8203;253](https://togithub.com/mvdan/gofumpt/issues/253)]
