Hi @Mike8040,
It patches a “Remote Code Execution” vulnerability so updating is very important.
Btw did you report the Polylang issue? Apart from the experimental filters, I could see your earlier report regarding the search element but with an edit saying that you were able to fix it: WAIT: Search element, 404 error for second language result page [Polylang] - #3 by Mike8040
Please correct me if I’m wrong or if you have another report I may have missed.
