How to update Cesanta Mongoose embedded web server

Open update page ↗
  1. Read the release notes first — self-hosted projects break config and schemas between versions more often than appliances do.
  2. Docker: pull the new image tag and recreate the container (`docker compose pull && docker compose up -d`).
  3. Package or bare metal: update through your distribution's package manager, or replace the binary from the releases page.
  4. Back up the config and database directory first. For most projects a downgrade is not supported once the schema has migrated.

Always install releases from the project itself. Firmwarely links out; it never hosts downloads.
