How to update the PlatformIO Embedded build 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.

FAQ

How do I update the PlatformIO Embedded build system?

See the step-by-step above. Follow the project's release page for the flashing or OTA procedure. Many maker devices update from a web installer or the project's desktop app.

How does Firmwarely know when there's a new version?

Every night we read the manufacturer's official release page for the PlatformIO Embedded build system and record the version, date and changelog. If anything changed, subscribers watching this device get an email.

Is this an official PlatformIO page?

No. Firmwarely is independent. Device and brand names belong to their manufacturers; always download firmware from the official source.
