[`v0.21.0`](https://redirect.github.com/google/yamlfmt/releases/tag/v0.21.0)

[Compare
Source](https://redirect.github.com/google/yamlfmt/compare/v0.20.0...v0.21.0)

Sorry to folks who were likely waiting on the stuff in this release,
it's pretty packed. I got sick in December and took my holiday leave
early, and I decided to fully and completely disconnect. Lots of stuff
packed into this one now that I'm back. Happy new year!

### Features

#### Force single or double quotes
[#&#8203;288](https://redirect.github.com/google/yamlfmt/issues/288)

You can now force all quoted strings in a yaml document to be `'` or
`"`. See the [`basic` formatter docs for more
info](https://redirect.github.com/google/yamlfmt/blob/main/docs/config-file.md#configuration-1).

#### KYAML Formatter
[#&#8203;302](https://redirect.github.com/google/yamlfmt/issues/302)

`yamlfmt` can now support the new [KYAML format from the Kubernetes
project](https://kubernetes.io/docs/reference/encodings/kyaml/). The
support for this is via a new formatter type called `kyaml`. I built
support for alternate formatters into the architecture of `yamlfmt` all
the way back when I first started the tool, but this is the first time
I'm actually publishing a new formatter. I recommend a full read of [the
formatter
documentation](https://redirect.github.com/google/yamlfmt/blob/main/docs/config-file.md#formatter)
to get a sense of how to use this alternate formatter.

### Bug Fixes

#### Gitlab output format
[#&#8203;272](https://redirect.github.com/google/yamlfmt/issues/272)

I don't use Gitlab and didn't implement the feature so I'm not sure if
this has been broken the whole time or if there was a schema change
somewhere that bricked it, but Gitlab output format from `yamlfmt` was
missing some required fields. This should work now with the new fields
added into the output schema.

#### `/dev/stdin` as an argument instead of `-` did not work
[#&#8203;291](https://redirect.github.com/google/yamlfmt/issues/291)

You're only allowed to read from `stdin` once in POSIX, but I
inadvertently had a codepath that would read the file for a different
purpose before reading it for formatting. This caused `yamlfmt` not to
work under that circumstance. This edge case is handled now.

#### Filepath collector panic
[#&#8203;300](https://redirect.github.com/google/yamlfmt/issues/300)

In a scenario where `filepath.Walk` fails to read something from the
filesystem, I wasn't handling the error case properly. This never came
up because I never had an error case ever appear locally and the linter
that would yell at me about missed error checks didn't pick up that
particular pattern that `filepath.Walk` propogates errors with. There
should no longer be panics in error scenarios; new behaviour is that
paths that failed to read will be surfaced and all other successful
reads will be formatted.

### Contributions
