2021.02 Release Notes

Release date: 23rd February 2021

Next release: 6th April 2021


[HTML-3450] - Refactor and Open Source IDRViewer
We are pleased to announce that the IDRViewer is now available on GitHub as an open-source (Apache-2.0) project.

In preparation for the open-source release, the IDRViewer also underwent a large internal refactor to increase encapsulation within the codebase with the goal of improving extensibility.

Please let us know if you have any questions and as always we welcome any suggestions you might have to improve BuildVu. We hope this change makes it easier for the IDRViewer to be extended to fulfill custom requirements.

The IDRViewer project can now be found at idrsolutions/idrviewer on GitHub.

[HTML-3400] - New experimental mode to detect & write links into annotations.json
An experimental mode has been added which detects links within the page text and writes them into the annotations.json file under a new annotation type TextLink (which are functionally the same as Link annotations).

This mode changes the existing functionality which hard-codes detected links within the HTML as anchor (<a>) tags. The benefits of this experimental mode are:

  • The behavior of detected links can now be customized by the annotations handling
  • Detected links are now supported in the SVG conversion (BuildVu-SVG)
  • Multi-line links are now detected
  • Ligatures (such as ffi/fi) are now handled correctly within detected links

This mode can be tested using the -DexperimentalLinkDetection=true system property. Please let us know if you have any feedback regarding this experimental feature.
