We’ve just released NetNewsWire 7.0.4 for Mac. Do a Check for Updates or download it directly to get the update.
The big new changes are to iCloud syncing: there’s a new setting to not sync the content of unread articles, since that’s the biggest part of your iCloud database and what takes the longest to sync.
Another change is a new iCloud Storage Stats window that tells you exactly what’s in your iCloud storage — and it includes a Clean Up button that will trim down your storage (and lead to faster syncs in the future, though not necessarily right at first).
