v2.0.0

Breaking

• Runtime updated from Node 20 to Node 24 (#​145, fixes #​132). Node 20 reached EOL in April 2026 and GitHub Actions runners default JavaScript actions to Node 24 from June 16th, 2026. GitHub-hosted runners are unaffected; self-hosted runners need version ≥ 2.327.1.

Changes since v1.6.6

• New version input to pin the Ghost Admin API version sent in request headers, defaulting to v6.0 (#​118)
• The action source was converted to TypeScript (#​138)
• Theme names derived from package.json are slugified (#​84)
• exclude patterns that look like CLI options are rejected to prevent argument injection
• Dependency updates throughout, including @tryghost/admin-api 1.14.9 and @actions/core v3

Internal

• The repo is standardised on pnpm with a pinned packageManager and hardened workflows (#​144)
• The major-version tag workflow now has an explicit contents: write grant and pins update-majorver to the v1.1.2 release (#​145)
