+## Changes in `v4.1.0-beta.1:`
+
+- **NEW - Preview:** Added video preview before downloading so ROSI can show the title, uploader, duration, thumbnail, playlist info, and other basic metadata before saving.
+- **NEW - Enhancements:** Added download options for embedded metadata, embedded thumbnails / cover art, subtitles with custom language codes, and SponsorBlock segment removal.
+- **Conversion:** Updated FFmpeg conversion to probe source codecs first, then copy compatible video/audio streams instead of re-encoding when possible.
+- **GPU detection:** Updated hardware acceleration detection to probe actual FFmpeg encoders, cache the result, and only claim a GPU path when that encoder can run.
+- **Typescript:** Migrated the main renderer engine from JavaScript to TypeScript and widened renderer type coverage.
+- **UI:** Split the renderer CSS into focused files, bundled local Manrope / IBM Plex Mono fonts, tightened CSP by removing remote Google Fonts, and added the preview/enhancement UI.
+- **FFMPEG:** Updated FFmpeg compliance docs, notices, source offer, and binary placeholders for FFmpeg `8.1` builds on Windows, Linux, and macOS arm64. macOS x64 stays on FFmpeg `8.0.1`.
+- **Testing:** Added jsdom DOM coverage for the renderer plus tests for video info parsing, codec-aware FFmpeg args, GPU probing, settings migration, IPC validation, and queue wiring.
+- **PKG:** Updated packages.
