- DeviceClient: solved logging bug
- EmulatedDriver: solved GetConfig bug and added event to prevent double connection requests
- DriverInstanceCache, DriverFactory: Added formatting of filter fields
- DataCache: solved minor bug
- DriverAPI test unit: corrected getconfig assertion check
- Device test unit: reimplemented, first complete test after component reworking
