  * New backup management system.

==== Evolutions====

===== Restrictions =====

  * **Configuration**
    * The result returned for the field ''rpmb_status'' in file ''/tmp/boar_info.json'' is not correct. This field must not be taken into account in firmware version 4.X. 
    * BNM frequency configuration files depending on the board (bnm-868.conf, bnm-923.conf, bnm-915.conf) are not kept by default when upgrading the gateway.
  * **Security**
    * Provenrun ''rpmb-status'' is not working on kernel 4.14.
  * **SMS Feature**
    * SMS command ''_operator'' doesn't receive a response when it's OK.
    * SMS manager command doesn't work on sierra_0 on Dual WAN iBTS.
  * **System**
    * Possible Kernel errors when using fixnetwork.
    * Default behavior of the ''store-config'' tool is to save the file ''/user/login'' that is not present in KerOS 4.x firmware.
  * **Update**
    * IPK update status is in error for all packages if only one package installation failed.
  * **Web Interface**
    * System manager error in the "Administration" menu when trying to configure a static IP whereas cellular backhaul is already defined as default connection (''main.conf'').
    * After a time modification more than 12h (token validity), the board does not reboot after pressing the "Reboot gateway" button.
    * When editing a cellular operator that is not used, it returns an error.
    * Sometimes GSM status stays green although the cellular is disconnected.


===== Firmware =====

  * Fully compatible with Wirnet iBTS ATc03 architecture and above.

<note warning>Due to multiple KerOS changes, **direct update in v4.x IS NOT COMPATIBLE from firmware v2.x & v1.x**.\\
It is required __first__ to update the gateway in v3.x to be able to update it after with the ''liveburner'' package v4.x.\\
