PROBLEM Cannot change pages?

[lotova]

I met impossibility to modify a page yesterday and searching the cause I realized that it must be related to recent upgrade to php 8 (debugging mode gave me weird announcements about undefined functions and so on, nothing of helping me). After reading this thread I downgraded my php installation to 7.4 version (and prevented its automatic upgrade) and previous functionality is back again. However: what are plans for near future in regard to compatibility of GetSimple CMS with PHP 8?
P.S. I have GS in version 3.3.16.
