We all need you to upgrade to version 3 if you are still using a version 2 of Reddcoin Core!
Especially if you’re staking! By upgrading to v3 you’re helping the progress of activating PoSV v2 (which basically means staking rewards can go up to 25%!).
Currently, most recent version is v3.10.0rc4. You can download it from here: https://github.com/reddcoin-project/reddcoin/releases/tag/v3.10.0rc4.
Make sure to make a backup first before upgrading!
