This announcement is uniquely intended for administrators having installed any mirror of MusicBrainz website with manually installed dependencies instead of using the Docker Compose project musicbrainz-docker.
MusicBrainz website is rendered using Node.js whose minimum required version was 16 so far. This version is reaching end-of-life next week according to their Release Working Group. Therefore MusicBrainz Server will switch to the active LTS Node.js 18 for a transitioning period of two months. It will still support Node.js 16 for previous installations during this period. After that, Node.js 20 will enter its active LTS phase and be required by MusicBrainz website. It has already been used locally in development for a long time, so we don’t expect any major issue when switching mirrors to it.
