+## 0.4.0 (2026-04-10)
+
+- Branch: v4 — video and audio corpus support
+- Add: drop `.mp4`, `.mp3`, `.wav`, `.mov`, `.webm`, `.m4a`, `.ogg`, `.mkv`, `.avi`, `.m4v` files into any corpus and graphify transcribes them locally with faster-whisper before extraction
+- Add: YouTube and URL download via yt-dlp — `/graphify add https://youtube.com/...` downloads audio-only and feeds it through the same Whisper pipeline
+- Add: domain-aware Whisper prompts — the coding agent reads god nodes from the corpus and writes a one-sentence domain hint for Whisper itself, no separate API call
+- Add: `graphify-out/transcripts/` cache — transcripts cached by filename; YouTube URLs cached by hash so re-runs skip already-transcribed files
+- Requires: `pip install 'graphifyy[video]'` for faster-whisper and yt-dlp
+
 ## 0.3.29 (2026-04-10)
