Upgrade / downgrade
Make sure you stay on the lookout for any critical updates to Nimbus. The best way to do so is through the announcements channel on our discord. The release page can be found here.
Note
If your beacon node is already running, you'll need to restart it for the changes to take effect.
To update to the latest version, either download the binary or compile the beacon node release (see below).
Tip
To check which version of Nimbus you're currently running, run build/nimbus_beacon_node --version
Binaries
Open the latest Nimbus release and download the file that corresponds to your operation system and machine.
Once downloaded, unpack the binaries in the same folder as your current version, overwriting the existing files.
wget <insert download link here>
tar -xzf nimbus-eth2_Linux_arm64v8*.tar.gz --strip-components 1 -C nimbus-eth2
rm nimbus-eth2_Linux_arm64v8*.tar.gz
