2.1.8

1. Alternative fix for COMException: MILERR_WIN32ERROR.
   There is a bug in .NET WPF that when creating too many RenderTargetBitmap, the MILERR_WIN32ERROR error can happen. This is reported as dotnet/wpf#3067 and there's no effective fix yet. Forcing a GC after each RenderTargetBitmap creation seemed to help.
2. Fixed a bug that the app always starts with 1 second tray icon refresh interval.

2.1.7

1. Properly handle COMException when rendering tray icon bitmap image.
2. Removed unnecessary locking status update check, this was potentially causing dead locks resulting in the tray icon update to stop under random circumstances.

2.1.6

1. New option to bring up main window with single click of the tray icon.
2. New tray icon menu item to shut down the device with configurable confirmation.

2.1.5

1. Handle COMException when rendering tray icon bitmap image.
2. Prevent some unhandled exceptions from crashing the app.

2.1.4

1. Fixed a bug that the GDI+ error may happen when battery is full.
2. Set tray icon font size to 16 when resetting all options to default.
3. New sleep device tray icon menu item.

2.1.3

1. Used a new rendering method for tray icon allowing customisable font size.
2. New tray icon font size settings UI.
3. More robust debounce logic to defend concurrent battery status update.

2.1.2

1. New notification button to disable the particular battery level alert.
2. New tray icon menu item to open system power settings.
3. Clicking on toast notification brings up the details view.
4. Default main window to hide at start.

2.1.1

1. Fixed a bug that can allow "ghost" instances of the app to stay in memory.
2. Added action buttons to battery status toast notification.
3. Always use native message box to show unhandled exceptions to allow Ctrl+C to copy error details and include app version in error message.

2.1.0

1. Added auto colour option for all configurable colours.
2. Better custom AccentColourPicker control.
3. Added black and white to available colours.
4. Debounced all battery status update calls with 500-millisecond buffer to further minimise back pressure problem.

2.0.9

1. Added "auto" option for normal battery colour.
2. Added black and white colour to tray icon colour selection.
3. Made minimum refresh interval from 1 second to 5 seconds.
   • 1 second was really for debug purposes. Because the app uses a timer to trigger each status refresh, having a refresh interval too short can cause a backpressure problem when the system is slower to process each status update than the set interval. A new status update will be queued by the timer before the previous one can finish. This can cause the queue to increase indefinitely resulting in an unpredictable error eventually.
4. Removed double refresh of the battery status triggered by the timer and a redundant observable subscription.
5. All events are debounced before triggering the battery status refresh.
6. Details page now uses the same refresh interval as set in the settings page.
