Hi!  wondering if i can safely upgrade to V5 ( and new cjlib4)... still running Joomal 3.10 on PHP8.0

Any essential security patches  or can I stay on previous version for a while??

( hope to move to J4 and Php8.1 or 8.2 in the next month... but still testing all new templates and legacy extensions and plugins, its a big process for live upgrade of big site)
