The API Playground has been significantly upgraded to save time and reduce repetition. Settings like your domain, context key, and release stage are now remembered between sessions, and every input field keeps a history of your last five values for quick recall. A unified launcher lets you switch between blocks, listings, trees, and pages without closing the dialog, and a new Page playground lets you test page delivery endpoints directly.

• Release Stage selector replaces the previous API Version pill — switch between develop, preview, and public stages and the request and code snippets update automatically

• Block key fields now include a search popover to browse and pick records from your storage directly

• The Authorization section is hidden on projects with no fetch secret configured

• Required parameters are validated before sending — the Send button shows you what's missing
