> I wish it has a .deb package..
Generally speaking, the Debian package management system is really not a place I would look for prompt updates when new versions of software are released.
Why not? It works roughly the same as any other binary distribution format. Given that the project is written in go, it's also unlikely to have many dynamically linked dependencies.
You might be confusing the .deb package format with the release cadence of the Debian Stable distribution.
