v0.2.23

• Updates
  • Several networking notebook additions and improvements. Thanks to Jon
    Carstens for these.
  • Pull in a subtle mDNS/DNS issue lookup issue that affected using .local
    addresses on some networks
  • Pull in Bluetooth support fixes. BLE works on Raspberry Pi Zeros and
    Raspberry Pi 3s now, but it's not convenient and there aren't any sample
    notebooks. We hope to change that soon.
  • You can transfer files using scp in addition to sftp from Nerves
    Livebook devices now.
