SIINEOS
-------

* Changes:
    - SMAC: added support for modeling an RS flip-flop with synthetic signals
    - SMAC: added method *Sum of all values* to the aggregation step in the signal processing page
    - SMAC: added new processing step *Delta* to the signal processing page
    - SMAC: performance of signal aggregation processing
    - SMAC: use `expr-eval library <https://github.com/oat-sa/expr-eval#expression-syntax>`_ for signal pre- and postprocessing steps and custom synthetic signal calculations - it's recommended to check the results of signal processing formulas and synthetic signals after the update and adopt the syntax wherever necessary
    - SMAC: added username/password authentication support to OPC/UA client
    - SMAC: added *Custom datatype* option to the *Measurement modelling* page, allowing to override the data type of a signal, e.g. when calculating a float value from a Modbus UINT16 register via signal processing
    - SMAC: dropped support for configuring a global OPC/UA interface namespace manually, instead users should always specify the full node IDs for OPC/UA client signals
    - SMAC: fixed crash when configuring Modbus registers
    - SMAC: various minor UI tweaks and tunings
    - InGraf: added login page for admin backend - a new user "ingrafadmin" with role "App administrator" has to be created in SMAC before logging in the first time
    - InGraf: added SMTP settings for Grafana allowing to configure and use e-mail alertions in Grafana
    - InGraf: added visual feedback for Grafana/Prometheus operations
    - InCore: added username/password authentication support to `OpcUaClientConnection`
    - InCore: fixed crash in `ModbusSlave` when receiving replies for already deleted registers
    - InCore: added more widget types to `DataObjectView`
