Bitcoin Core - Warning: unknown new rules activated

Howdy folks, just a quick question about my Bitcoin Core full node from a technology noob. I opened my Core back up on windows desktop today after a month or so. After catching up with the new blocks it says “Warning: unknown new rules activated (versionbit 2)” in an orange banner across the top. Should I be concerned or can I ignore it? Version is 0.20.1 (main) and I just use the core as a way to interact with my specter software for my hw wallet.

Edit: Yes I know my core is an old version but I would rather not update it if I don’t have to.
