On www.getmonero.org it says that the latest version to download is Lithium Luna 0.12.2.0, but when I download the zip file, it says the zip file name is 0.12.0.0. I'm having trouble when sending funds, as it hangs forever and then often says that daemon isn't connected. I thought the new version may fix this, but don't see it posted for download.
If you need latest GUI, build from source yourself. If you just need the daemon/
monero-wallet-cli, official CLI build is (correctly) up to date.
