Personally, I would prefer to read the features of the update, and if I do not need it, there is no need to update that wallet.

In any case, when you update, remember to keep your cold storage as  "air-gapped" (it has not been connected to the Internet and will not be connected) and therefore download the latest version using tails^[1] or any Linux versions, when you need to sign a transaction.
