    * OTA file: "poco-fw-ota_4p1-rc8.bin" - MD5: d1c3bc5bf2d2e4101c5219fc1b5f4db6 - CRC32: c539caaa
    * FW: 4.1-rc8 * IDF: 4.4.8 * WebUI: 4.1.9 
    * FW Changes:
      - Backported: Start ExtSw ID at 0. Allows creation of Action# 0 to map to N2K Lighting Zone Index 0.
      - Backported: Fix mapping of ExtSw ID to N2K Lighting Zone Index
      - Backported: added a call to increment the switch State Sequence Number whenever the config is reloaded to fix stale N2K switches. fixes #43.

    * WebUI Changes:
      - WebUI bumped to 4.1.9. Backported: Start ExtSw ID at 0. Allows creation of Action# 0 to map to N2K Lighting Zone Index 0.

    We have corrected the mismatch between the Poco External Switch ID (Action#) and N2K Lighting Zones. This may be a breaking change for some 3rd-party integrations.
 
    * Before the change (Poco FW 4.1-rc5)
      - Poco Action #0 was not available.
      - Poco Action #1 maps to:
        * NMEA 2000 Lighting Zone -- Index 0 (first)
        * NMEA 2000 Binary SwitchBank -- first switch in first bank  (typ. named Switch 1)
        * ExtSw HTTP API -- id=1
    
    * After the change (Poco FW 4.1-rc7+)
      - Poco Action #0 maps to:
        * NMEA 2000 Lighting Zone -- Index 0 (first)
        * NMEA 2000 Binary SwitchBank -- first switch in first bank  (typ. named Switch 1)
        * ExtSw HTTP API -- id=0
      - Poco Action #1 maps to:
        * NMEA 2000 Lighting Zone -- Index 1 (second)
        * NMEA 2000 Binary SwitchBank -- second switch in first bank  (typ. named Switch 2)
        * ExtSw HTTP API -- id=1
 
    * Note: for now, you must use the Web version of our Poco GUI to be able to add an action of ID=0. It will be available in the next release version of the mobile app (to be v4.2).
    * Note: Existing Poco configurations will not be automatically adjusted for the mapping change upon firmware update. Some users may need to adjust the mapping manually after upgrading Poco firmware.
