Stage CMS 0.3.0

The workspace stays responsive as content grows: searchable, paginated images; a visual cover picker that saves the draft first; and revision summaries with individual reading views.

Agent lists return compact summaries. Read a page or revision for complete content, or request include=body. Media lists now use pagination; follow next_page. The CMS guide is available at /api/guide, including when a website supplies its own /llms.txt.

Upgrading from 0.2: clients that read bodies from page/history lists must request them explicitly. Clients that read the image library must follow pagination. Write requests, PHP full-content list methods, and database format remain compatible.

Requires Stage 0.1.1 or later. Includes an isolated, repeatable benchmark. Composer validation, PHPStan max, 24 tests with 208 assertions, OpenAPI response validation, and desktop/mobile editing checks passed.
