PHP 8.4 Deprecation Error "Implicitly marking parameter as nullable"

[at-ac]

According to emconf t3sbootstrap 5.3.30 the EXT should work with PHP 8.4.
Unfortunately there are a few deprecation errors.

In my case most of them are in: t3sbootstrap\Classes\Utility\ResponsiveImagesUtility.php
Area $focusArea = null,
?Area $focusArea = null,
^ a question mark can solve it.

Will there be a bugfix version?

thanks

The bug is known and has already been fixed in the dev version for TYPO3 v14 (completely new).
You can download the developer version here and explore the new documentation.

Unzip the ZIP file and integrate the EXT locally.
