Release iText Core 7.1.12

The iText Core 7.1.12 release is the third quarterly release of 2020 of our innovative PDF library. 

This Core release brings initial support for <linearGradient> in SVG and linear-gradient() in CSS, which is something that both Core, and pdfHTML 3.0.1 will benefit from. SVG is an important topic for us, so be sure to check our future releases, as even wider support is coming.

As for the rest of the changes, expect the typical ongoing mix of yet more performance improvements and convenience additions.

A big shout-out to evileye-uktompecina and hady-malekpour for their pull requests! It is pretty amazing that after 20 years as an open source project, we still get contributions.

As always, we try to synchronize the release with some of our other add-ons, so besides Core, be sure to also check out:
