netlab release 1.8.2 contains dozens of bug fixes and minor tweaks to device configuration templates. We also added a few safeguards including:

• Check for Vagrant boxes or Docker containers before starting the lab and display pointers to build recipes.
• Check installed Ansible collections before trying to configure the lab devices.
• Display a warning if the lab topology was modified after the lab was created

You might also enjoy:

• Creating reports from a subset of nodes (I use that to display BGP neighbors of customer routers in the BGP labs)
• Inspecting the same variable(s) across multiple nodes (an ideal tool to find data model discrepancies)
• Improved Vagrant-box-building process

Finally, someone asked for Sonic support, so I added a minimal implementation based on what I could squeeze from Azure VM images after wasting too much time trying to get Dell Enterprise Sonic to work.
