**New Config Options**
The following config options were added
In the `[settings]` section:
* `pseudo-transparency`
In `internal/cpu`:
* `ramp-coreload-spacing`, spacing between elements in `<ramp-coreload>` elements
* `%percentage-sum%` in `label`. Shows sum of all percentages
In `custom/script`:
* `double-click-left`
* `double-click-middle`
* `double-click-right`
In `internal/pulseaudio`:
* `interval`, volume increase and decrease steps in percentage points
In `internal/memory`:
* `bar-swap-used`
* `bar-swap-free`
* `ramp-swap-used`
* `ramp-swap-free`
**Deprecations**
* `tray-transparent` in the bar section is no longer used. The tray now always uses pseudo-transparency
