What's New in Miteiru 8.0.1

Changes since v7.6.3.

Installed 8.0.0 on 7 November? That was an early build of 8.0; 8.0.1 is the finished release. Install it over 8.0.0, and your words and settings stay. 8.0.0's notes said it would update itself, but 8.0 doesn't: new versions appear on the releases page and at miteiru.hocky.id. Since that build: - the Windows installer is 60 MB instead of 130 MB, and installs 10 files instead of 21,310; - each language downloads when you first choose it, and dictionaries open without being rebuilt first; - subtitles inside MKV and WebM files open without FFmpeg; - everything under Easier to use below is new.

Miteiru 8 is rebuilt on Tauri and mpv. It no longer ships its own copy of Chromium: the interface runs in the system's webview, a small Rust core handles files, processes and storage, and video plays through libmpv.

Plays nearly any video, without converting

• Any file mpv plays opens directly: MKV, MP4, HEVC (including 10-bit), AV1, DTS, AC-3 and the rest, with hardware decoding where the system has it.
• The "convert this video" prompt is gone. Files with several audio tracks show a short list to pick from instead, and switching is instant.
• Subtitles inside MKV and WebM files open without FFmpeg. Miteiru reads the SRT, ASS, SSA and WebVTT tracks itself, so anime episodes work out of the box. Subtitles inside other containers, such as MP4, still go through FFmpeg, and Miteiru says how to add it when it's missing.
• YouTube plays in the same player when yt-dlp is installed (in Miteiru's tools folder or on your PATH; brew install yt-dlp on macOS). You get hardware decoding, Miteiru's subtitles with none of YouTube's drawn over them, and videos that refuse to play embedded. Without yt-dlp, YouTube plays in its own player as before.

A smaller download, and languages when you need them

• The Windows installer is about 60 MB, a third of 7.6.3's 181 MB, and installs 10 files. Language data isn't in it any more. Each language downloads the first time you choose it, from this release, and is checked before it's used:

Chinese and Cantonese share 11 MB of character stroke data, so the second of them is smaller.

• No internet on that computer? Download the language's Miteiru-language-<name>.mtrpack files from this release, then choose Install it from a file… on the home page, or Settings & tools → Languages → Install from a file….
• Dictionaries are read as they are, with nothing to build first: a language is ready in well under a second, even the first time. The dictionary caches 7.x built, often a few hundred MB, are cleared from the data folder; your words and notes stay.
• Settings & tools → Languages lists what's on this computer, with Remove, Update and Download.

Easier to use

• While watching:
• A bar at the top (Home, Open…, Subtitles…, My words, Shortcuts) fades with the controls.
• Continue watching opens the last video where you left it, with its subtitles.
• Looking up a word pauses the video, and closing the word resumes it.
• ? lists every shortcut, and Ctrl+Shift+P searches all commands.
• Saving words:
• The word popup shows New / Learning / Known.
• Right-click a word in the subtitle to save it, and Miteiru says what it did.
• A colour key explains the word colours.
• Flashcards review only the cards that are due, then say All done for today and when the next review is.
• Subtitles:
• Timing controls in the video settings, and [ / ] while watching.
• show.ja.srt or show.en.srt next to a video load into the right place.
• The track picker uses plain names.
• When a helper tool is missing, Miteiru says which one and how to add it.
• Study a text starts with one box; the AI tools stay folded away until you add a key.
• Keyboard and screen readers:
• Dialogs take focus and close on Esc.
• Closed panels leave the Tab order.
• Focus rings are visible.

The same app, on a new base

• Your data carries over. Miteiru 8 uses the same data folder as 7.x, so your words, notes, Anki settings and preferences are still there. Learning data moves into a new SQLite store the first time you open it; the old copy is left untouched.
• A simpler home page: pick the language you're learning from four cards, then press Watch a video. Country flags now show on Windows too.
• Full screen: F11 (Ctrl+Cmd+F on macOS). Ctrl + / Ctrl − zoom the interface.
• The window opens at the size and position you left it.
• Links that open a new window go to your browser.
• Updating: 8.0 doesn't update itself. New versions appear on the releases page; download them as you did this one.
• The analyzer API for other tools keeps the same endpoints, token and analyzer-server.json.

Downloads

• Windows: Miteiru_8.0.1_x64-setup.exe.
• macOS (Apple silicon): Miteiru_8.0.1_aarch64.dmg, replacing the .pkg. Still not notarized: open it anyway.
• Linux: Miteiru_8.0.1_amd64.deb and .AppImage, built on Ubuntu 22.04. Video plays through the system's libmpv: the .deb installs it; for the AppImage, install libmpv2 (libmpv1 on Ubuntu 22.04).
• Language packs: Miteiru-language-*.mtrpack. Miteiru downloads these itself; they're here for installing without a connection.
• On Windows, Miteiru 8 installs beside 7.x rather than over it; uninstall 7.x afterwards if you like. Your data stays either way. Installing 8.0.1 over 8.0.0 replaces it, and clears the language data 8.0.0 kept in its folder.
