Push QPDF member variables into a nested class
...

member variables without breaking binary compatibility.

Detect loops in /Pages structure
...
Pushing inherited objects to pages and getting all pages were both
prone to stack overflow infinite loops if there were loops in the
Pages dictionary. There is a general weakness in the code in that any
part of the code that traverses the Pages structure would be prone to
this and would have to implement its own loop detection. A more robust
fix may provide some general method for handling the Pages structure,
but it's probably not worth doing.
Note: addition of *Internal2 private functions was done rather than
changing signatures of existing methods to avoid breaking
compatibility.

For std::string and std::vector, replace operator[] with at. This was
done using an automated process. See README.hardening for details.

Handle /Outlines dictionary being a direct object

seen, and caused an internal error.

Limited inheritance to the attributes explicitly listed in the PDF spec
...
Previous versions of qpdf incorrectly passed arbitrary objects from
/Pages objects down to individual pages in direct contradition with
the PDF specification. These are now left in /Pages. When
intermediate /Pages nodes are being discarded as when the /Pages tree
is being flattened, a warning is issued when unknown keys are
encountered.
