Sixth release of yt-dlp GUI.
This one adds 8K. If a video's available in 4320p, you can now pick "4320p (8K)" from the quality list right alongside the usual 4K, 2K and 1080p options, and the app will prefer the highest resolution when deciding which format to grab.
Everything else stays the same: paste a link, pick the quality, and download.
On 2026.09.03 or older, the app will update itself to this build.
