Firmware update channels: Stable vs Latest

Firmware channels for S-line

Since firmware 6.2, Ultimaker offers two channels of firmware for S-line printers. You can choose to subscribe to your preferred channel:

Latest The Latest channel is selected by default. This channel contains the most recent firmware including new features, improvements, and bug fixes. All firmware releases are thoroughly tested internally by our engineers. There is a new release available on the Latest channel approximately once every 6 weeks.

The Stable channel has a slower release cadence. All features and improvements included in Stable releases will be thoroughly tested not only be Ultimaker, but field-tested on the Latest channel for at least 3 months. There is a new release available on the Stable channel approximately 3 or 4 times per year. Sometimes, releases can appear faster in case of critical bug fixes or security updates.

Note: Firmware channels are only available on S-line printers (Ultimaker S3, Ultimaker S5, and the Pro Bundle).

Which channel should you choose?

We generally recommend updating to the Latest version. This ensures that your printer is always equipped with the latest features, improvements, and bug fixes. However, if your workflow requires fewer updates and less frequent changes, change your subscription to the Stable channel. This ensures a more stable workflow, but you will receive improvements and non-critical bug fixes much later.

How to configure the firmware channel

By default, the Latest channel is selected. If you want to change this to Stable, or later revert back from Stable to Latest, you can easily do this either via the touchscreen menu on the printer, or via Ultimaker Digital Factory.
