The Jars are now signed with SHA256 rather than SHA1.
Added the ability to allow signatures, that have just been signed, to be queried via various "get" methods.
Improved the pre-flight process for large embedded fonts, e.g. those used for Chinese, to stop the widths array growing too large for PDF/A.
Improved the workaround for when 2-byte fonts are used in Form fields, which reduces memory footprint for large forms.
PDFCanvas.beginTag() will now accept a "ref" attribute which is a space separated list of ids (or uuids) of other nodes, to be converted to the PDF2 "Ref" property on the element. It will now also cleanup name 'atts' (e.g. Table:Scope) which had values set with incorrect leading slashes.
The PDF Library will now consistently choose the correct rendering intent from ICC ColorSpaces when converting to PNG.
Minor tweaks to OutputProfile in anticipation of PDF/UA-2.
Added the ability to set the appropriate feature when private-use range text is added to a PDF.
Minor bulletproofing to let the PDF Library work with some more types of damaged files.
