Release notes

Sourced from next's releases.

v16.3.8

This release contains security fixes for the following advisories:

Medium:

• Information disclosure in Next.js App Router metadata image routes via dynamicParams bypass
• Cache poisoning of SSG and ISR pages in self-hosted Next.js applications
• Cache poisoning in Next.js SSG/ISR rendering leads to cross-user content substitution and persistent denial of service
• Pending use cache fill can leak Draft Mode content into regular responses and persisted pages
• Cache leak across root param values in nested 'use cache' functions

Low:

• Information disclosure in the Next.js development server's Model Context Protocol endpoint

v16.3.7

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

Quick checklist before review (most of these are enforced by CI, but worth a glance):

• make quality — ruff format check, ruff check, mypy, pytest (≥80% coverage), and the rest of the gate
• Panel changes pass pnpm lint and pnpm exec tsc --noEmit (run from panel/)
• No # noqa / # type: ignore shortcuts; pre-existing violations in touched files are fixed
• Added an entry under ## [Unreleased] in CHANGELOG.md
• Signed the CLA (the bot will prompt you on this PR)
• Signed your commits — master requires verified signatures (SSH signing setup)
• Updated any affected docs under docs/

See CONTRIBUTING.md for the full workflow and the Code of Conduct for the community standards we follow.

Welcome aboard — a maintainer will review shortly.
