@ -12,11 +12,16 @@ Biggest differences with v2 are:
- Added market capitalization screen
- LED flash on new block (and focus to block height screen on new block)
New features:
- BitAxe integration
- Zap notifier
-
"Steal focus on new block" means that when a new block is mined, the display will switch to the block height screen if it's not on it already.
Most [information](https://github.com/btclock/btclock_v2/wiki) about BTClock v2 is still valid for this version.
**NOTE**: The software assumes that the hardware is run in a controlled private network. The Web UI and the OTA update mechanism are not password protected and accessible to anyone in the network. Also, since the device only fetches numbers through WebSockets it will skip server certificate verification to save resources.
