Hey there,
you can easily update this mod by yourself:
- Go to your mod folder
- Open the Zip/Rar archive (I'm using WinRar)
- Edit info.json using Windows Editor
- change "factorio_version": "0.14" to "factorio_version": "0.15"
- Save changes
- Mod is working again.
I've tested this today and it works pretty fine.
THANKS TO PALICRAFT for this little hint, found on the Waterfill-Mod page.
