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:
