====== Wirnet™ iFemtoCell KerOS firmware v4.0.4 (March 2019) ======

===== Changes from v3.4.5 =====

==== Release corrections ====

  * LED will shutdown at halt.
  * Various Webui corrections and improvement.
  * Fixed: Use of a roaming SIM yields SIM registration but not attach (e.g. no data).
  * Fixed: When the gateway date is manually changed in the web interface, a reboot retrieves the auto date.
  * Fixed: GSM config tab in webui displays the wrong operator parameter.
  * Fixed: Changing date manually then rebooting has no effect (NTP date takes over the manual date).
  * When a static IP address is used, DNS can be configured through the webui.


==== New features ====

  * Writable File system.
  * Webui handles cellular multi-provisioning.
  * Required fields in operator of GSM tab.
  * SMS feature handles most of the same configuration as the webui.
  * Add KerOS REST API access. 
  * New backup management system.
  * New package management system.
  * "System status" (CPU, RAM & disk usages, temperature) displayed in "Overview" webui.
  * Allow specifying netmask as prefix-length (CIDR notation) - tested through SMS & webui.

==== Evolutions====

  * Kernel updated to 4.14.9.
  * Global package update.
  * Discovery performance and stability improved.
  * An error is displayed on failed WiFi connection on the webui.
  * ''CONFIG_IP_MULTIPLE_TABLES'' is now present on KerOS 4.0.x.
  * IPSec connection with basic PSK authenticated configuration and without ProvenCore works on keros 4.0.x.
  * The argument ''network.gsm.broadcast'' has been removed from Webui on KerOS 4.0.x.
  * In the webui, the passphrase of WiFi service is not displayed when trying to connect to another WiFi.
  * Set the wrong passphrase when connecting to WiFi service displays an error.
  * IPTABLES logging added in ''/var/log/messages'', also visible on the console.
  * Bootcount in U-boot and in ''/tmp/board_info.json'' on KerOS 4.0.x.

===== 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.
  * **System**
    * Sometimes, Failed to start LNA for BNM.
    * Sometimes, the measurement is not accurate at +/-2dB.
    * Possible Kernel errors when using fixnetwork.
    * Version of ''util_fpga_start'' is "dirty".
    * 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.
  * **WiFi**
    * Impossible to connect with an Android system to Acces Point WiFi of the gateway.
    * No fallback on WiFi.
    * No passphrase entered starts a WPS connection.
  * **Ofono**
    * With USB cellular dongles UX302NC and UX302NCR, APN provisioning does not work if SIM has a PIN code.
    * Sometimes, cellular backhaul keeps the priority over the ethernet connection.
  * **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 returns an error.
    * Sometimes GSM status stays green although the cellular is disconnected.
    * Sometimes, WiFi tab not displayed on webui.
    * When GSM is enabled on webui, "Save configuration" first is necessary before to add an operator.
    * When adding an operator in GSM tab, MCC must be 3 digits and MNC 2 or 3 digits (recommendation ITU-T E.212).
    * No feedback on PIN code verification, webui just disables GSM on wrong PIN Code.


===== Firmware =====

==== Compatibility ====

=== Hardware ===

  * Fully compatible with Wirnet iFemtoCell BEb02, BEc03, BQa01 and BPa01 architecture (architecture can be retrieved from the final product ID).
  * Partially compatible with Wirnet iFemtoCell BEa01 architecture.
  * List of compatibles USB cellular dongles is available [[wiki:cellular_backhaul_ifemto|here]].


=== Software ===
