I have just posted version 2.9.0 of the plugin. The change in the plugin are:
- Update: Set "get_cover" to as appropriate when getting metadata. This should improve performance in some places.
- Update: Handle changed reading location for epub starting with 4.17.13651. Should be backwardly compatible with currently stored locations and older firmware.
- New: Add options to cover updating for dithering, letterboxing and PNGs to match the driver change. Based on work from @NiLuJe.
- New: Add option to remove the full sized cover image.
The last one is the only one that is any way risky. This removes the cover image used for the sleep screensaver. Removing it will save a lot of space. But, the device will use one of the smaller cover images for the screensaver. This will mean the sreensaver will use a low resolution image and will look terrible.
Calibre will announce the update in the next hour or so. If there are any problems with the plugin, please report them here.
