Release iText 7.1.10

iText 7.1.10 brings the first quarterly release of 2020 for the iText 7 family, and coincidentally it's on the day that iText, as a project, turns 20!

Although it's iText's birthday, we are giving away presents left and right, which include new releases of Core, pdf2Data, pdfCalligraph, pdfHTML, pdfSweep, pdfXFA and RUPS (oof, I really had to take a breather there. It's a lot of goodies!) Head on down to the Release Notes to get the details.

Lots of goodies going around! In no particular order:

• Core now has some improved memory usage, specifically if you are reading big PDF files (check out PdfReader#SetMemorySavingMode(true)), more robust PDF update mechanisms, a better PDF/A document experience, some dependency updates and <marker> support for SVG;
• pdf2Data has even better table boundary detection;
• pdfCalligraph has much improved Thai and Gujarati language scripts' support;
• pdfHTML now supports the lang attribute. This will help with the creation of PDF/UA compliant documents; 
• pdfSweep had a bug which would remove /ColorSpace when redaction would partially affect an image;
• pdfXFA has much better dynamic page numbering handling.

Also, a couple of points mostly of interest for our commercial customers:

• It is now required that the License Key Volume library is loaded if you are a Volume customer;
• Proxy environment variables will be honored for Volume reporting;
• If your license expires during runtime, it will revert back to AGPL mode.
