Changelog index as JSON 

Every manual is rendered with a table of contents as JSON. The TYPO3 Core Changelog gets one artifact on top that no other manual does: a machine-readable index of its entries, one file per major release, written beside the overview page it belongs to.

Changelog-13.json sits next to Changelog-13.html and Changelog-13.md and lists the same entries the overview page lists:

{
    "major": 13,
    "entries": [
        {
            "permalink": "https://docs.typo3.org/permalink/changelog:deprecation-104764-1724851918",
            "path": "Changelog/13.3/Deprecation-104764-FluidTemplatePaths-fillDefaultsByPackageName",
            "html": "Changelog/13.3/Deprecation-104764-FluidTemplatePaths-fillDefaultsByPackageName.html",
            "md": "Changelog/13.3/Deprecation-104764-FluidTemplatePaths-fillDefaultsByPackageName.md",
            "title": "Deprecation: #104764 - Fluid TemplatePaths->fillDefaultsByPackageName",
            "anchor": "deprecation-104764-1724851918",
            "type": "deprecation",
            "issue": 104764,
            "typo3-version": "13.3",
            "typo3-major": 13,
            "tags": ["PHP-API", "FullyScanned", "ext:fluid"],
            "classes": {
                "\\TYPO3\\CMS\\Core\\View\\ViewFactoryInterface": [
                    { "section": "migration", "kind": "inline" }
                ],
                "\\TYPO3\\CMS\\Fluid\\View\\TemplatePaths": [
                    { "section": "description", "kind": "inline", "members": ["->fillDefaultsByPackageName()"] }
                ]
            }
        }
    ]
}

path

The entry's file within the manual, without an extension.

html

The entry's page, relative to this file: path with .html. Left out when the Changelog was not rendered to HTML page by page.

md

The entry's Markdown, relative to this file: path with .md. Left out when the Changelog was not rendered to Markdown page by page.

permalink

The URL that names the entry wherever its file ends up. The Changelog is deployed to main only, so these never carry an @version.

title

The headline of the entry, for example Feature: #105638 - Modify fetched page content.

anchor

The label the entry is known by: what the permalink resolves against, and what a link to the entry has to name.

type

One of feature, breaking, deprecation or important.

issue

The Forge issue the entry documents.

typo3-version

The release the entry belongs to, read from its path, for example 13.4.x. The document's own version is main for every entry and therefore says nothing.

typo3-major

The major of that release, so a consumer can filter on it without parsing the version.

tags

The terms of the entry's .. index:: directive, such as Frontend or ext:core.

classes

The PHP classes the entry speaks of, by their fully qualified name, each with the places in the entry: the section, kind and members of the class index, which says the same by class. A class under migration is often what replaces the one under description or impact. The page and release are the entry's; a place names an anchor only where it lies below a label of its own inside the entry. Left out for an entry that names no class.

Entries are ordered newest release first, matching the overview page, and within a release by issue, so the file does not change between two renders of the same sources.
