## Changelog

### September 7, 2026

##### Version 2 (VIF 1.1.0)

VIF 1.1.0 introduces the VIF REST API v2, served on `/v2/vif` alongside the existing v1 API. v2 replaces v1's flat configuration document with a layered model: a default config, a matching stream group config, a per-stream override, and any runtime changes, each layer filling in whatever the one below it left unset. Endpoints are grouped by what they work with: framework-wide status (`Server`), the streams currently running (`Runtime`), durable configuration saved to disk (`Persist`), connectivity checks (`Probes`), and on-demand video analysis (`VOD`).

VIF REST API v1 is deprecated
The v1 API is deprecated as of 1.1.0, and Wowza strongly urges customers to move any integration to v2. A v1 write rewrites the configuration in the old format and silently breaks settings saved through 1.1.0 — per-stream overrides lose their meaning and stop layering over their defaults. See [How to upgrade to Wowza Video Intelligence Framework 1.1.0](/docs/wowza-video-intelligence-framework/upgrade-to-vif-1.1.0) before you upgrade.

**Highlights:**

- Added the VIF REST API v2, replacing the flat v1 configuration document with layered stream group configs, per-stream overrides, and runtime state.
- Added VOD (video on demand) analysis endpoints which help you with analyzing VOD files.
