Breaking Changes

Dropped Python 3.7 support when using [mqtt] or [telegram] feature (due to update to aiomqtt and aiogram 3.x)
Default line interpolation style of un-aggregated ChartWidget plots changed to LINEAR. To return to the old behaviour, add line_interpolation=shc.web.log_widgets.ChartLineInterpolation.STEP_BEFORE to the respective ChartDataSpec. See line_interpolation in the Docs for more info.

New Features

Python 3.12 support
All Python and frontend dependencies updated to the latest version
New utility class DelayedVariable
New display options for shc.web.log_widgets.ChartWidget:
- Area charts, dots or pure line charts via plot_style
- custom line interpolation (stepped vs. smooth) via line_interpolation
- Stacked lines/areas via stack_group

base: Improved state synchronization between multiple state-full objects on concurrent updates. The existing implementation for preventing conflicting updates turned out to be not sufficient to prevent inconsistent state of multiple connected connectable objects in all cases.
web ui: Only connect to websocket when the current page contains dynamic widgets (esp. do not connect to websocket on monitoring web page)
MySQL: Allow storing NaN in float-type variables
