Release notes

Sourced from eslint-config-next's releases.

v16.2.12

What's Changed

• Backport/docs fixes 16.2 - July round by @​icyJoseph in vercel/next.js#96031
• [Backport] Fixes to support TypeScript 7 by @​lukesandberg in vercel/next.js#95831

Full Changelog: vercel/next.js@v16.2.11...v16.2.12

v16.2.11

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

v16.2.10

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

v16.2.9

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.

v16.2.8

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

v16.2.7

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

Maintainer changes

This version was pushed to npm by GitHub Actions, a new releaser for eslint-config-next since your current version.

[zaccesss]

Held, not a safe merge. eslint-config-next 16 requires eslint >=9, this project pins eslint 8.57.1 on the old .eslintrc config format. Bumping eslint to 9+ is itself a flat-config migration, not a drop-in bump.
