Tabs
What's Changed
The Tabs engine is now more efficient in how it fetches its records:
- The Tabs engine no longer clears the DB on every sync.
- Tabs now tracks the last time it synced and only fetches tabs that have changed since the last sync.
- Tabs will keep records for up to 180 days, in parity with the clients engine. To prevent the DB from getting too large.
