#BTClock firmware 3.4.0 is out, a reliability-focused release! New features: Pool-wide hashrate for the #Noderunners pool, and a Moscow-time toggle for the USD sats-per-dollar screen. Under the hood: every TLS handshake is now serialised behind a firmware-wide gate, the WebSockets RX path stays in DRAM, HTTP responses stream, and the WebUI ships as a single JS chunk for faster ESP32 load. Plus a pile of fixes — mempool WS survives 18 KB history bursts, no more ghost Nostr relays, Bitaxe JSON is happy with numeric fields, LEDs stop false-flashing when WiFi is down. Use the auto-updater in the WebUI, use the web-flasher at https://web-flasher.btclock.dev/ or compile it from source yourself https://git.btclock.dev/btclock/btclock_v3 If you use Home Assistant, you can also integrate it with the custom #BTClock integration: https://github.com/dsbaars/homeassistant-btclock
