 **Whishper** is an open-source, 100% local audio transcription and subtitling suite with a full-featured web UI.
 
 ## Features

 - [x] 🔥 **GPU support**: use your NVIDIA GPU to get even faster transcription times!
 - [x] 🐎 **CPU support**: no GPU? No problem! Whishper can run on CPU too.
 
+The Docker images pin `yt-dlp` to `2026.08.19` and include Deno `2.9.5`, which yt-dlp uses to solve YouTube JavaScript challenges. Both versions can be overridden at build time with the `YT_DLP_VERSION` and `DENO_VERSION` build arguments (update `YT_DLP_SHA256` when changing yt-dlp).
