Is CFDB+ PHP 7 compatible?

Hi,
Thanks for this usefull plugin! I′m using itsince some time and I really like it.
Now I have to update my PHP at least to 7.0, better higher and therefore I tested all plugins with the PHP-Compatibility-Checker-Plugin, which says the contactic-plugin has 19 errors. This checker tool cannot detect unused code paths that might be used for backwards compatibility, potentially showing false positives.
So my question is: Are the following errors this kind of false positives, or is the CFDB+ not compatible with 7.0 and higher?

Here are the shown errors:
