CHANGELOG.json Update Guidelines

Use this guide whenever editing CHANGELOG.json.

Scope and Source of Truth

• This file applies only to CHANGELOG.json.
• The canonical history source is CHANGELOG.json.
• CHANGELOG.md is generated from CHANGELOG.json by scripts/CHANGELOG.js.

Required JSON Structure

CHANGELOG.json must remain a valid JSON array of release objects.

Each release object must use this exact field set and order:

1. date
2. version
3. Changed

Example shape:

{
  "date": "2026-02-16",
  "version": "4.202602.0",
  "Changed": [
    "Update dependency X",
    "Improve behavior Y"
  ]
}

Formatting Rules

• Keep strict JSON (double quotes, no comments, no trailing commas).
• Keep the existing indentation/pretty-print style used in the file.
• Keep Changed key capitalization exactly as Changed.
• Keep Changed as an array of strings.

Ordering Rules

• Keep entries in reverse chronological order (newest release first).
• Add new releases at the top of the array.
• Do not reorder or rewrite historical entries unless explicitly requested.

Content Style Rules

• Write concise, factual change statements.
• Keep one distinct change per string entry.
• Preserve existing tone: practical release-note language, not marketing copy.
• Include links (issues, PRs, docs) only when relevant and known.
• Avoid placeholders like "TBD" or unverifiable claims.

Field Conventions

date

• Required format: YYYY-MM-DD.
• Use the release date, not implementation start date.

version

• Follow existing project version patterns already present in the file.
• Keep exact string format used historically (for example 4.202602.0).

Changed

• Use non-empty strings only.
• Prefer complete statements that can stand alone in generated markdown.
• Keep each item specific enough to be useful to end users.

Safety and Compatibility Checks

Before finalizing edits:

• JSON parses successfully.
• New entry is at top (if adding a release).
• Field names and field order are correct.
• Changed contains only strings.
• Existing historical entries were not unintentionally modified.
• Content is consistent with actual implemented changes.
