================ in-tech smart charging Charge Control C =======================
================         Firmware Release Notes          =======================
================================================================================
Release Date:	  2020-05-11
Release Maturity: Beta
Release Version:  0.6.0

Important notes for this firmware update:
  - before doing the firmware update make sure that the firmware version is at least 0.4.0
  - during the firmware update the currently installed /etc/secc/customer.json
    will be preserved; a pristine, factory default configuration file
    is contained in the firmware update and will be available as
    /etc/secc/customer.json.shipped after the firmware update

    - fix handling of BootNotification (offline behavior, RegistrationStatus = Pending / Rejected)
    - fix handling of PowerMeterFailure, ReaderFailure and ConnectorLockFailure
    - fix case sensitivity in authorization cache and LocalAuthList
    - fix several issues which prevent charging
    - fix several wrong StatusNotifications on state changes
	- fix wrong behavior in case from going from Unavailable to Faulted
    - filter whitespace from URLs in UpdateFirmware.req and GetDiagnostics.req
    - fix handling of ConcurrentTx after starting a transaction
    - avoid sending dummy token "-", this is now usable for RemoteStartTransaction
    - implemented generic data transfer
	- implemented OCPP Offline mode
	- implemented LocalAuthList (only method FULL of SendLocalList, GetLocaLListVersion)
	- implement config parameter to allow RFID authentication while an EV is connected
    - fix endless loop of startTransaction messages for unexpected transaction id
    - allow new transaction while in Finishing
    - fix unexpected authorization behavior during Unavailable state
    - fix missing StatusNotification for inoperative connector after reboot
    - fix behavior after going from Unavailable to Faulted state
    - implemented range check for MeterValueSampleInterval
    - avoid flood of "Txn data full!" in log file
    - fix issues in hostname verification for TLS
    - start transaction only in case the plug lock is properly closed
    - avoid sending StopTranstraction twice
    - UnlockConnector doesn't return unlock in case the connector has never been unlocked
    - fix issues with storing of availability of a connector
	- fix issue where Charge Control C accidentially tries to stop transaction 0
	- implemented new config parameter SupportedFileTransferProtocols (readonly), StopTransactionOnInvalidId, AllowOfflineTxForUnknownId, LocalAuthListEnabled, LocalPreAuthorize, LocalAuthorizeOffline
	- provide a vendorErrorCode for StatusNotifications with ChargePointErrorCode "OtherError"
	- provide an idTag for most StopTransaction cases
	- prevent transaction stop for different RFID cards
	- signalize a missing meter via LED
	- fix issue where the connector state accidentially goes to Unavailable
	- fix parameter handling of ocpp/verifyCert
  
- powerctrld
  - RCD monitor implemented
  
- recloserd
  - Geya RCD recloser implemented

- meteringd:
  - make RS485 communication more reliable
  - support for Klefr meters

- rfidd:
  - make RS485 communication more reliable

Untested:
  - real RCD monitor
  - generic data transfer with a customer application & central system

Not fixed:
  - occasional unexpected green LED blinking
  - Modbus scan wrongly detects DZG meter instead of ignoring different Modbus device
  - firmware downgrade from Yocto to Debian image can cause out-of-memory errors
  - BootNotification contains chargeBoxSerialNumber with value 0
  - CP state E during charging is reported as EVDisconnected
  - Wrong behavior of changeAvailability during charging session
  - GetDiagnostics fails to upload to the desired URL under certain circumstances
  - ChangeConfiguration without change to the actual value results in "RebootRequired"
