Software version: 1.7.0
=======================
Date: 25.9.2018

New features:
- From this version on Operations will reject downgrade of major or minor version of itself. Downgrades of bugfix versions are still allowed, as we don't change database or settings structure in bugfix versions. If version is X.Y.Z: X = major, Y = minor, Z = bugfix. Downgrades of other parts of the system are still possible (as long as Operations is not included in the package).
- Measuring maximum current in response to MeasureMaxCurrent message from Power Management.
- Operations now reports meter values to PM every 2 seconds if change is > 0.2 in current or power measurement.
- All meter measurements that are passed to PowerManagement are now freshly read. Also the driver version shipped with this edition doesn't cache meter readings (previously meter reading could be up to 2s old).
- Optimized web server so that less class instances are created.
- Added reporting of consumed memory every 10 minutes.
- We're now using Evse.EvseCode in place of StartCode.

Bug fixes:
- Added help text for PIN screen in Slovenian translation.
- As part of solving "frozen LCD" bug, all OCPP messages regardless of protocol are now being added to a queue before sending. This should also help ensure messages that are being sent are not lost in case of Power Loss.
- As part of solving "frozen LCD" bug, touching LCD now doesn't require a ThreadPool thread. Also vendor animation doesn't use ThreadPool anymore. There are however other cases that still involve ThreadPool.
- Fixed incorrect TimeZone setting (CentralEurope instead of Europe/Berlin).
- Some chargers are missing Factory settings, which means if user selects Factory Reset this will break the charger. Operations will now copy current settings to Factory folder if they are missing.
- Fixed: some chargers have Identity=DEFAULT in Factory settings. This will be overwritten with Idenity from currently active settings.
- Fixed: when power management was disabled and no charging profile was active, current was set to 14A of 15A (depending on car characteristics) instead to cable max.
- Updated screen borders to show less white on the edges.
- Fixed session sync with Power Management.
- Fixed popup icon & Sonnen leaf positions.
- Fixed: if center makes charger Unavailable and then sends Available, the charger didn't become available again.
- Fixed "Charging in power mode" written over some other text on screen.
- Fixed: If a file didn't exist in Config folder and needed to be upgraded, it got upgraded in Config\Factory and didn't get copied to Factory.
- Fixed: in websockets communication, if server didn't respond in time that could prevent reception of future responses.

### Power Management
- WARNING for customers that were already testing Power Management: All existing power management settings will be replaced with new default settings.
- Local master is now always enabled, so that operations web can change power management settings.
- Added hysteresis to prevent switching charging on/off very quickly.

Bug fixes:
- Fixed: PowerManagement always had the same version of settings as Operations.

### Installer
- Added installation types TestUI and Generic.
