Summary

Docs for pdfjs-viewer 4.5.0, which is on npm. It adds renderer-src (missing-elements/pdfjs-viewer#77) and narrows the open() type (missing-elements/pdfjs-viewer#79).

• Version bump to 4.5.0. The page takes its version numbers from the package, so the PDF.js version shown is now 6.5.438. The site's vendor copy now includes pdf.renderer.min.mjs.
• renderer-src is added to the attribute table and the TypeScript attribute list.
• Worker section: how to turn on worker rendering with setViewerOptions({ disableWorkerRendering: false }), the CSP it needs, when to set renderer-src, and what happens when the worker can't start.
• Hosting: the renderer file sits next to the other runtime files. Pipelines with hashed file names need renderer-src when worker rendering is on.
• Migrating: a note for 4.4.2 and earlier. A pinned worker-src must move to PDF.js 6.5, and TypeScript now rejects a bare Uint8Array in viewerApp.open().

Validation

• pnpm build passes. The built page shows 6.5.438 seven times and 6.4.299 nowhere.
• All 57 in-page links point to an existing id.
• The renderer-src row renders with its default and "Next load".
