libnpmpublish: v12.0.0-pre.0

on GitHub

12.0.0-pre.0 (2026-06-19)

⚠️ BREAKING CHANGES

• npm now supports node ^22.22.2 || ^24.15.0 || >=26.0.0
• opts.access now defaults to null instead of 'public'. With null, libnpmpublish no longer sets an explicit access level in the publish payload, so new scoped packages are created as restricted (registry default) and republishes preserve the existing access level. Callers that want to force public access must now pass access: 'public' explicitly.
