What's New in Miteiru 7.5.0

Changes since v7.4.9.

Features

• LRCLIB lyrics search (sidebar button, M, command palette) is available only in karaoke mode.
• Mandarin tone types now match the labels: num is contour marks plus the tone number (niᵛ₃); symbol is standard diacritic pinyin (nǐ). Jyutping num uses the same contour style.
• Changing tone type or traditional/simplified restyles the current subtitle immediately, without reopening the file picker.
• Ruby / furigana / pinyin sit centered over a longer base instead of stretching to the edges.

Fixes

• YouTube "unknown error 152" — the embed no longer claims youtube.com as the host; player requests still use YouTube's own Referer.
• Ctrl+V pastes a YouTube URL into the player via the clipboard event (Electron blocks navigator.clipboard.readText()).
• Toggling subtitle settings no longer stacks miteiru_normalized_ temp files until Windows cannot open the path.
• Windows NSIS builds clean renderer/.next first so a leftover Turbopack cache cannot fail packaging.

Developer notes

• npm run lint:smells plus GitHub Actions ci.yml (smell lint + unit tests on PRs and main).
• Dependencies refreshed with npm run update:safe (versions published at least 7 days ago), including Electron 41.10.6, Next.js 16.3.2, and Nextron 10.3.0.
• Video protocol unit tests no longer put Windows file paths into Request URLs (Node's URL parser rejects them).
