Please test go-yaml rc.7 before the November 4 release #14432

Description

@ingydotnet

Hi, I maintain yaml/go-yaml.

I plan to release v4.0.0 on Wednesday, November 4, 2026.

I selected Docker Compose for this testing request because it directly depends on
a go-yaml v4 release candidate and has over 1,000 GitHub stars.
Your current go.mod requires v4.0.0-rc.6.

Could you test with the newly published v4.0.0-rc.7, including your normal
tests and any YAML parsing or serialization checks?

go get go.yaml.in/yaml/v4@v4.0.0-rc.7

Please report any problems in comments on the go-yaml release issue
yaml/go-yaml#469
, so we can track them together before the release.
Please include the project revision, Go version, failure output, and a small
reproducer if possible.
A comment there confirming successful testing would also be helpful.
Results by Tuesday, November 3 would be appreciated, but later reports are
welcome.

Thanks for helping test the release!
