Version annotated: 5.0.9
Identified issues:
Identifier: timestamps_in_pdf_generated_by_latex
URL https://wiki.debian.org/ReproducibleBuilds/TimestampsInPDFGeneratedByLaTeX

ModDate set to the current date and time.
Identifier: graphviz_nondeterministic_output
Description graphviz appears to use a non-deterministic algorithm to optimally lay out
notes optimally. This can appear in class hierarchy documentation, etc. Can
presumably affect images of all complexity but, obviously, more likely to
affect images with lots of nodes.
