+## Highlights
+### Changed
+- Launcher: Removed the YouTube subtitle generation mode switch so YouTube playback always preloads subtitles before mpv starts.
+
+### Fixed
+- Launcher: Hardened YouTube AI subtitle fixing so fenced SRT output and text-only one-cue-per-block responses can still be applied without losing original cue timing.
+- Launcher: Skipped AniSkip lookup during URL playback and YouTube subtitle-preload playback, limiting AniSkip to local file targets where it can actually resolve anime metadata.
+- Launcher: Keep the background SubMiner process running after a launcher-managed mpv session exits so the next mpv instance can reconnect without restarting the app.
+- Launcher: Reuse prior tokenization readiness after the background app is already warm so reopening a video does not pause again waiting for duplicate warmup completion.
+- Windows: Acquire the app single-instance lock earlier so Windows overlay/video launches reuse the running background SubMiner process instead of booting a second full app and repeating startup warmups.
+
+## Installation
+
+See the README and docs/installation guide for full setup steps.
+
+## Assets
+
+- Linux: `SubMiner.AppImage`
+- macOS: `SubMiner-*.dmg` and `SubMiner-*.zip`
+- Optional extras: `subminer-assets.tar.gz` and the `subminer` launcher
+
+Note: the `subminer` wrapper script uses Bun (`#!/usr/bin/env bun`), so `bun` must be installed and on `PATH`.
