Perhaps you have some package depending on libglib2.0-dev (=2.66.8-1). There are several
ways to list dependent packages, i.e. reverse dependencies. But what you need is a way to
determine the packages that depend on a certain version of a dependency.
Try with this:

$ aptitude -v --show-summary=all-packages-with-dep-versions why <package_name>

In my system:

~$ aptitude -v --show-summary=all-packages-with-dep-versions why libglib2.0-dev
Paquetes que dependen de libglib2.0-dev:
  libgtk-3-dev D: libglib2.0-dev (>= 2.57.2)
  librsvg2-dev D: libglib2.0-dev (>= 2.50.0)
  libvte-2.91-dev D: libglib2.0-dev (>= 2.40.0)
  libwnck-3-dev D: libglib2.0-dev (>= 2.32)
  libxfce4panel-2.0-dev D: libglib2.0-dev
  libxfce4ui-2-dev D: libxfconf-0-dev D: libglib2.0-dev
  libxklavier-dev D: libglib2.0-dev (>= 2.16.0)

Cheers,
