I updated (git pull) and performed git checkout v0.3.0.0 and when i execute git status, it shows head detached at v.0.3.0.0, and binaries are dated today, but when i type version on the wownerod status screen, it still shows Busty Brazzers' (v0.2.0.0-master-7859424, hope it's just a label thingy...
It seems to have synced to the latest block height per the wownero blockexplorer and v9 shows up on the status.
I had the same issue. Apparently you need to do a fresh clone to get the version message to update, but yea, it's just a label thingy and not a real issue.
