v1.8.0

Using custom shapes? This release changes your configuration

This release simplifies the shapes variables. It's no longer necessary to define a shape based on your configuration. For example: main_needle_with_inner no longer exists in favour of the (already existing) main_needle.

Complete list of merged variables:

• main_needle_with_inner -> main_needle
• main_min_indicator_with_inner -> main_min_indicator
• main_max_indicator_with_inner -> main_max_indicator
• inner_needle_on_main -> inner_needle
• inner_setpoint_needle_on_main -> inner_setpoint_needle
