Installation using Docker in an air-gapped environment

Self-host Installation
1

The following flags do not work in air-gapped environments:
PENPOT_FLAGS: enable-air-gapped-conf

Online, Docker installation and 6 containers worked normally. However, when offline, 1 container (frontend:latest) out of 6 containers did not work. It shows the error log below.
host not found in upstream “raw.githubusercontent.com” in /etc/nginx/nginx.conf:140

Why doesn’t the above PENPOT_FLAGS work?
Is this only possible with an Enterprise account in an air-gap environment?

This applies to 2.8 version, which is still unreleased to on-premise users. We expect release it on the end of the week.

I tested it today and it seems that the on-premise version has not been updated to version 2.8 yet.
According to the changelog on github, it seems to be in the Unreleased state. Is that right?

When is it expected to be released?
