# Release notes {% hint style="success" %} MClimate is devoted to keeping our products up to date with the latest advances in the space of IoT. Thus, we push updates for the purpose of introducing New Features or in order to improve Existing Functionality. We are committed to making our products better! We have made the option to update the firmware of your device (check improvements each version brings below) via a remote update. Learn on how to initiate the update in the [FUOTA section](/mclimate-lorawan-devices/firmware-upgrade-over-the-air-fuota.md) of our documentation. {% endhint %} **Would you like to receive news about new firmware updates for our products?**\ **Subscribe to our newsletter via the link below.** {% embed url="" fullWidth="false" %} ### Firmware version 1.4 **Release date:** \ 26 September 2025 * Bug fix - radio no longer gets stuck in busy state. * Improved device restarting radio command functionality - the device now sends one last keep-alive after receiving the command. * NEW! - the device can now go into deep sleep mode (command code A8), new devices with this firmware will come in deep sleep out of the box and will not have a plastic tab on the battery. In order to start the device for the first time you need to perform the wake-up procedure (consult the [User Manual](/mclimate-lorawan-devices/devices/mclimate-multipurpose-button-lorawan.md) or the [A8 command page](/mclimate-lorawan-devices/devices/mclimate-multipurpose-button-lorawan/mclimate-button-lorawan-device-communication-protocol/network-related-settings-and-others.md#deep-sleep-activation)). ### Firmware version 1.3 **Release date:** \ 15 February 2025 * Fixed incorrect battery voltage reading. * Fixed a bug related to the [command for LED control](/mclimate-lorawan-devices/devices/mclimate-multipurpose-button-lorawan/mclimate-button-lorawan-device-communication-protocol/led-control-command-explanation.md). * Added radio command to set up the [uplink type](/mclimate-lorawan-devices/devices/mclimate-multipurpose-button-lorawan/mclimate-button-lorawan-device-communication-protocol/uplink-types.md). * Аdded radio command to set up the [radio watchdog](/mclimate-lorawan-devices/devices/mclimate-multipurpose-button-lorawan/mclimate-button-lorawan-device-communication-protocol/network-related-settings-and-others.md#communication-watch-dog). * Added a radio command to read the [radio region](/mclimate-lorawan-devices/devices/mclimate-multipurpose-button-lorawan/mclimate-button-lorawan-device-communication-protocol/network-related-settings-and-others.md#lorawan-region). * Added a radio command to [restart the device](/mclimate-lorawan-devices/devices/mclimate-multipurpose-button-lorawan/mclimate-button-lorawan-device-communication-protocol/restart-device.md). * Added radio commands to read and clear the [button press event counters](/mclimate-lorawan-devices/devices/mclimate-multipurpose-button-lorawan/mclimate-button-lorawan-device-communication-protocol/button-press-event-counters.md). * Changed the default [1E command](/mclimate-lorawan-devices/devices/mclimate-multipurpose-button-lorawan/mclimate-button-lorawan-device-communication-protocol/network-related-settings-and-others.md#set-send-event-button-later-when-it-is-allowed) to send the message when it's allowed. * Added firmware update mechanism - FUOTA. {% hint style="info" %} The FUOTA functionality differs from the FUOTA that's being used by the LoRa Alliance. In order to update the firmware version of devices, they should be connected to MClimate's cloud. It takes around 1500 downlinks to perform FUOTA. Due to duty-cycle limitations of the gateways, we recommend staging the FUOTA in smaller batches in case your installation is sizeable. Feel free to reach out to to acquire more details on the process. {% endhint %} ### Firmware version 1.2 **Release date:** \ 17 Oct 2023 * Added functionality to control the green LED with a radio command. {% hint style="info" %} **Known issues:** Battery voltage readings might be reported as lower than they actually are. Don't be alarmed - device will continue operating as normal. {% endhint %} ### Firmware version 1.1 **Release date:** \ 6 April 2022 * Change the delay time with the sleep delay time. * A new command has been added - send the button event later when allowed. ### Firmware version 1.0 **Release date:** \ 11 February 2022 * Initial firmware release --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
