HexaPDF - HexaPDF 0.15.0

This release brings support for flattening annotations, i.e. making the appearances of annotations part of the page content itself.Since AcroForm fields also use annotations for their visual display, this functionality also allows flattening of form fields. Form field flattening can now also be done with the hexapdf form CLI command.Additionally, basic support for the AcroForm signature field was added. However, this does not allow signing a PDF yet.There is also a breaking change with respect to how annotation appearances are accessed. The change simplifies getting the correct appearance stream.As always, have a look at the changelog for an overview of all changes.
