Debian future release strategy proposal Rev2

• Follows on from https://github.com/nodejs/docker-node/issues/2398
• Relates to https://github.com/nodejs/docker-node/issues/2397

Current situation

According to the settings in versions.json Node.js 22 & 24 are set to use Debian 12 (bookworm/oldstable) as default, Node.js 26 sets Debian 13 (trixie/stable) as default.

Images are built for each of the Debian major versions: 11 (bullseye/oldoldstable), 12 (bookworm/oldstable) & 13 (trixie/stable) (see Debian Releases).

Debian releases transition through milestones:

• Release
• End of Life (EOL) after 3 years
• End of LTS after another 2 years, 5 years in total

When Debian transitions from EOL to LTS, the LTS support team typically define and publish LTS support architectures that are a subset of the architectures supported during the original release phase.

Docker Engine typically removes a Debian release from their required version list when that version transitions to End of LTS.

Current release line suggestions

For existing release lines Node.js 22, 24 & 26, retain Debian version support as long as covered by upstream Debian & Docker support.

Transitions

From Debian releases in the year 2026:

Current bookworm / bookworm-slim architectures

From versions.json

Future release line suggestions

For the future Node.js 27, Alpha Oct 2026, followed by Node.js 27.0.0 in April 2027, consider restricting to support Debian stable and oldstable (2 versions) only. This would require changes in update scripts.

Start with versions.json and the linked Debian releases, Debian LTS architecture, and Docker Engine support references. Compare the proposed Node.js 22, 24, 26, and future 27 policies against the listed transition dates and architectures; done means the release strategy and any required update-script changes are agreed and documented.
