What's Changed

• Backport/docs fixes 16.2 - July round by @icyJoseph in https://github.com/vercel/next.js/pull/96031
• [Backport] Fixes to support TypeScript 7 by @lukesandberg in https://github.com/vercel/next.js/pull/95831

Full Changelog: https://github.com/vercel/next.js/compare/v16.2.11...v16.2.12

This release contains security fixes for the following advisories:

High:

• Denial of Service in App Router using Server Actions
• Middleware / Proxy bypass in App Router applications using Turbopack and single locale
• Server-Side Request Forgery in rewrites via attacker-controlled destination hostname
• Server-Side Request Forgery in Server Actions on custom servers

Moderate:

• Cache confusion of response bodies for requests with bodies
• Cache confusion of response bodies for requests with bodies containing invalid UTF-8 byte sequences
• Denial of Service in the Image Optimization API using SVGs
• Unauthenticated disclosure of internal Server Function endpoints
• Unbounded Server Action payload in Edge runtime

Contains no changes except publishing @next/swc-wasm-web which was accidentally not published since 16.2.4.

Empty release to ensure next@latest points at a stable release. Next.js only allows publishing with Trusted Publishing enabled. In order to fix NPM dist-tags, we have to release a new version. Updating dist-tags is not possible with Trusted Publishing.

Release with no changes in an attempt to fix next@latest pointing at a prerelease version.

[!NOTE] This release is backporting bug fixes. It does not include all pending features/changes on canary.
