Release iText 7.1.1

iText 7.1.1 is the first scheduled maintenance release for iText 7.1 Community. We're also updating pdfHTML to 2.0.1, and releasing pdfXFA 2.0.0.

The biggest news is that iText has taken its first steps to support .NET Standard 1.6. The frameworks that we are targeting are .NET Core 2.0, .NET Framework 4.6.2, UWP Fall Creators Update, Xamarin iOS, Xamarin Android, and Xamarin Forms. This hasn't been fully tested yet, so consider this as an experimental build for these platforms.

iText 7 Core/Community 7.1.1 for Java - for .NET

  • Improvements in font handling: irregular Panose, encoding entries that are PDF Stream objects, and the font selector algorithm.

  • Link annotation improvements.

  • Alignment bugs for floating elements, large tables, and landscape mode.
  • Image extraction and PNG color profiles.

pdfHTML 2.0.1 for Java - for .NET

  • Improvements in CSS handling: @font-face, inherit.
  • Borders: border-radius, and non-continuous borders with a large radius.

pdfXFA 2.0.0 for Java - for .NET

  • Compliance with iText 7.1.x.
  • Compliance with license key library 3.0.1.
  • Fixed layout problem during flattening.
