How to update Jupyter JupyterLab

Open update page ↗

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.

Always download firmware from the manufacturer or project itself. Firmwarely links out; it never hosts firmware.

FAQ

What is the latest version of Jupyter JupyterLab?

Version 4.6.3, released Aug 10, 2026. This page is refreshed every 30 minutes from the manufacturer's release page.

How do I update Jupyter JupyterLab?

See the step-by-step above. Pull the new image or package and restart the service. Read the release notes and back up the data directory first; most projects can't downgrade once the database has migrated.

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

Every 30 minutes we read the manufacturer's official release page for the Jupyter JupyterLab and record the version, date and changelog. Subscribers watching this device get one email a day when it changed.

Is this an official Jupyter page?

No. Firmwarely is independent. Project and product names belong to their owners; always install releases from the project's own source.
