[pdf] Better handling of pre-existing FontConfig configurations on modern Linux systems.
[office] Fix for potential incorrect font selection when handling mixed arabic and latin text.
[office] Tune substitute font scaling so that we are less likely to end up extreme scaling factors.

[office] Fix for rare crash when processing Excel sheets with text that overflows cell boundaries.
[office] Fix for potential crash when handling format strings with particular symbols in the string portion.
[office] Better thread safety for internal font metric lookups.
[office] Fix for failed doc conversions in some isolated cases where expected parts of the source file are missing.
[office] Fix for incorrect scaling of some rotated picture elements.
[office] Tuned list indentation for powerpoint files.
[pdf] Avoid errors when Optimizing due to direct fonts in the PDF.
[pdf] Fixed a memory leak in Digital Signature Verification. This also impacts Secure Timestamping and LTV support since these use Verification.
[pdf] Fixed a rare issue where Linearized PDFs could be detected as not linearized.
[pdf] Fixed an issue where Digital Signature Verification could disallow certain Long Term Validation updates.
[pdf] Fixed issues with Unicode writing ElementWriter APIs in Node.js.
[pdf] Updated line annotation appearance generation (used when displaying or creating lines) to better take line dashes into account. Previously the phase would be different than expected.
[pdf] When printing the print and hidden annotation flags are now properly taken into account.
[pdf] Handle corrupt document where the Annotations entry is not an array in FlattenAnnotations.
[pdf] Better handle uncommon fonts with 3 byte charcodes.
[svg] Handle corrupt cases where the PDF has graphics state changes in BT/ET blocks for PDF to SVG conversion.
[pdf] Updated font Substitution on Apple platforms to handle unicode characters beyond the basic multilingual plane.
[xfdf] Fixed a problem where in rare situations extracting XFDF from PDF could produce a document with an incorrect and large font size.
[pdf] Long Term Validation support will now update rather than rewriting existing Long Term Validation data.
[pdf] Fixed an error with Page.GetBoundingBox which could cause it to malfunction on corrupt documents with mismatched group begin and group end elements within a form. This also had an impact on Page flattening which uses this method.
[pdf] Diff.AppendVisualDiff will now better take into account the page rotation and cropping present in the input pages.
[xfdf] Simplified the conditions for exporting annotation appearances in XFDF. In particular they will now be included even if that the annotation type is unsupported or certain annotation entries are missing.
