The checked-in release docs separate engine changes from web UI changes. That keeps packet-analysis releases distinct from interface and workbench updates.

**Current engine version**, v1.9.1, documented on February 26, 2026.

**Current web UI version**, v1.9.0, documented on February 25, 2026.

**Live track**, Separate history is maintained for the live-viewer and streaming-oriented app layer changes.

## Versioning model

The project release docs define a split versioning model:

- The engine version tracks changes to `_ms_engine.py`, tshark behavior, and report format.
- The web UI version tracks `app.py` plus templates and UI behavior.
- The live release document tracks the web and Docker orchestration layer for live or streaming functionality.
