When the libraries are installed transitively as part of an application
install, then after an update, distribution package managers usually
check which of these libraries are no longer needed and suggest removing
them.

To avoid that can install a library explicitly
(e.g. via =apt-get install libpng-dev= for the dev headers of libpng)
then after an update, libpng-dev stays available.

Best wishes,
Arne
