# September 09, 2026

Nested document collaboration threads, flexible date-range credit analytics, and zero-row table schema preservation.

See what’s new and improved in our latest update.

### Grouped Replies & File Attachments in Page Comments

* Discussion threads in Diaflow Pages now group replies into clean hierarchical conversations, keeping context intact.
* Upload file attachments directly into comment threads (up to 25 MB) with dedicated downloadable asset preview cards.
* Author-only edit and delete protections safeguard discussion history from accidental modification.

### Custom Date Range Filter in Analytics

* Filter credit usage, token consumption, and flow execution trends by arbitrary start and end dates.
* Isolate billing spikes and track team usage over monthly or quarterly billing cycles.
* Direct CSV export of filtered usage datasets for internal reconciliation and reporting.

### Zero-Row Table Schema Preservation

* Tables containing 0 rows now preserve their complete header schema and column configurations instead of collapsing into a blank empty-state canvas.
* Smooths out empty state transitions for newly provisioned tables and active filtered views.
* Downstream automated flows and webhooks can immediately map columns even before initial row data is populated.
