 New features:
 - BitAxe integration
-- Zap notifier
+- Nostr Zap notifier
-- Braiins Pool and Ocean mining stats integration
+- Multiple mining pool stats integrations
 
 "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.
+See the [docs](https://git.btclock.dev/btclock/docs) repo for more information and building instructions.
 
 **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.~~ Since 3.2.0 the WebUI is password protectable and all certificates are verified. OTA update mechanism is not password-protected. 
 
 ## Building
 
-Use PlatformIO to build it yourself. Make sure you fetch the [WebUI](https://github.com/btclock/webui) submodule.

 Enable mining pool stats by accessing your btclock's web UI (point a web browser at the device's IP address).
 
 Under Settings -> Extra Features: toggle Enable Mining Pool Stats.

+For solo mining pools, there are no earning estimations. Your username is the onchain withdrawal address, without the worker name.
