What is new in AirStats 1.5

### New

- 24-hour history charts under each panel module and in the desktop widget, which mark time on the charger and name the process behind a peak
- Top memory users in the memory module
- Accessory batteries in the battery module
- Compact Bar, a menu bar style with its labels stacked beside the bar
- A status dot style for the network readout

### Improved

- The panel opens one module at a time and is a little wider
- Less background work while the panel is closed

### Fixed

- Disk keeps purgeable space across restarts and hides disk images
- Per-core bars fit the panel on chips with many cores
