Dependency Details

Component: Viewer
Current Version: 2.2.2
Target Version: --

Motivation

The sh upgrade has caused an outage across Anthias devices. I glanced at the code and found that sh isn't used too often, so it's kept as a dependency.

Let's move to Popen and remove sh at all.

Scope

• Direct dependency upgrade
• Requires additional dependency updates
• Breaking changes expected
• Database migrations required
• Configuration changes needed

Research

Potential Breaking Changes

Required Steps

1. Remove sh
