[Printing-architecture] Forth beta of the second generation of the Common Print Dialog Backends released!

Hi,

We are now releasing the fifth beta of the second generation of the 
Common Print Dialog Backends (CPDB).

Main change is the removal of the backend info files, in a standard 
installation in the /usr/share/print-backends/ directory. They are not 
actually needed, all containing the D-Bus object path /, which we can 
simply hard-code, and we also cannot use the files to determine which 
backends are there, as both the frontend and the backends can be 
provided in a sandboxed package, like a Snap or an OCI container 
(podman, Docker, …), and so cannot read each other’s file systems.

So frontends communicate with backends purely by D-Bus, not any more by 
the file system.

In addition, we have fixed several bugs, especially security 
vulnerability CVE-2023-34095, a buffer overflow due to unlimited 
scanning of input strings by scanf() and fscanf() calls, some crashers, 
and a bug breaking make install.

The components we are currently maintaining got all updated and released 
as version 2.0b5.

Here we go:
