The github.com/hashicorp/terraform-json Go module in its entirety is versioned according to Go module versioning with Git tags.
There is currently no firm plan for releasing v1.
Releases are made on a reasonably regular basis by the Terraform team, using our custom CI workflows. There is currently no set release schedule and no requirement for contributors to write changelog entries.
The following notes are only relevant to maintainers.
Create new release via GitHub UI to point to the new tag and use GitHub to generate the changelog (Generate release notes button).
You can format the generated changelog before publishing - e.g. ensure entries are grouped into categories such as ENHANCEMENTS, BUG FIXES and INTERNAL.
