Upgrading the CLI¶
We release new features, bug fixes, and other updates for the h3-cli on monthly boundaries. Upgrade your installation using one of the methods below.
From the CLI, enter: h3 upgrade
Support for this command started with the June, 2023 release.
If you get an ERROR: unrecognized command: "upgrade", then you are on an earlier version of h3-cli that does not support the upgrade command. Use one of the adjacent options to upgrade h3-cli.
Run this command from h3-cli's parent directory (i.e., the directory that contains the h3-cli/ directory):
curl -L https://downloads.horizon3ai.com/utilities/cli/easy_install.sh | bash
Previously downloaded the repo as a zip file? Then re-download the zip file and unzip it to the same location (in other words, replace your existing h3-cli installation with the new zip).
Using the OVA host virtual machine? If you update the host using the Host Utility script, this will also update the h3-cli version and any Runners on the host.
Checking the current version¶
As of June, 2023, you can view your current version of h3-cli via:
h3 version
Updating the source location¶
Prior to July, 2025, h3-cli pulled CLI (and Runner) updates from github.com. As of July, 2025, new CLI deployments and new Runner installations now pull from downloads.horizon3ai.com.
If you have older installs and want to switch their source (for future updates) to downloads.horizon3ai.com, log into your NodeZero host and run h3 upgrade ng. This will pull future updates from the new location. It will also remove the requirement for network access to github.com.
