Next.js 15: security releases to January 31, 2027

The Next.js support policy says Maintenance LTS for 15 was extended past its original end date of October 21, 2026. Security releases continue through January 31, 2027.

The status table shows 16.x as Active LTS, released October 21, 2025, and 15.x as Maintenance LTS. 14.x and older are listed as unsupported.

Phase	What ships
Active LTS	New features, bug fixes, performance work, security patches
Maintenance LTS	Critical bug fixes and essential security updates only

Example

Illustrative. 5 apps on 15, about a week each. Start with the smallest in late November and you land the last one in January, with holiday weeks left out.

Important

The policy warns that updates in Maintenance LTS land as semver-minor releases, even if they are breaking changes. Read notes before you bump a minor version on 15.

Plan the move

• ☐ List apps by Next.js major version
• ☐ Check which ones are on 14 or older
• ☐ Read notes for each 15.x minor
• ☐ Set a date per app
