How to update the Rt Thread RT-Thread is an open source IoT Real-Time Operating System
- Read the release notes first — self-hosted projects break config and schemas between versions more often than appliances do.
- Docker: pull the new image tag and recreate the container (`docker compose pull && docker compose up -d`).
- Package or bare metal: update through your distribution's package manager, or replace the binary from the releases page.
- Back up the config and database directory first. For most projects a downgrade is not supported once the schema has migrated.
