The bitcoin core team has release an update. Release notes are here
The following are instructions for upgrading Bitseed to Bitcoin Core 0.11.2
The instructions add an upgrade script to the device. It will delete your old binaries and replace them with the latest binary files built by Bitseed. The script will stop bitcoind and then restart it when done. All blockchain data and settings will remain unchanged.
ssh into the device (windows can use putty)
password: (printed on bottom of device)
rm bitcoin-upgrade.sh wget -4 https://bitseed.org/device/latestversion/bitcoin-upgrade.sh
chmod 755 bitcoin-upgrade.sh
Bitcoin will then restart. Allow 15 minutes for it to verify the blockchain and start up.
