Christmas Release of all SetaPDF Components - 2020-12-22 ▷ setasign.com

Christmas Release of all SetaPDF Components2020-12-22

With this SetaPDF release we want to wish you a Merry Christmas and a Happy New Year!

We hope you made the best from this strange year and you are looking forward to better times coming, too.

This release comes with new minor versions for all SetaPDF components. We ensured compatibility with PHP 8 and added several tweaks, small features and bug fixes. Most work was done in the SetaPDF-Core component which results in improvements for all components.

We also rewrote all demos with a nice GUI and put them into a public respository at GitHub. It is also planned to have these demos living on a live site so we can give you more ideas and more better support when it comes to "how can I do" questions. As soon as this is deployed you will get an update from us.

Some highlights of this release:

PHP 8 compatibility for all components.
A new TempStream writer class was implemented to reduce CPU an memory usage.
The SetaPDF-FormFiller component can finally handle XFA forms without data-bindings.
The HttpCurlResolver in the SetaPDF-Signer component got a retries option when resolving validation related information (certificates or CRLs).
All demos are completely rewritten.

Added SetaPDF_Core_Canvas_Draw::polygon() method.

Bugfix

Fixed fallback logic in Flate filter class.
Ignore invalid references in AcroForm data and handle them as they would not exist.
Allow DateTimeInterface instances in set*Date() methods in Annotation classes.
Handle missing encoding information in Type0 font instead of throwing a fatal error.
Handle empty Keyword array in XmpHelper class.
Resolve values of FontBBox array in several font classes (instead of accessing it directly).
Fixed access to undefined annotation appearance streams.
Added compatibility for PHP 8.
Handle invalid /Parent values in form field structures.
