Katevazo v0.6.0

Added

• Katevazo now updates itself. It checks for a new version shortly after launch and every few hours, downloads it in the background, and shows a banner with Restart to update. Nothing is installed until you click it, and running downloads are named before they are interrupted. Settings shows the update status. Updates are signed and hosted on GitHub Releases.

Changed

• yt-dlp now updates itself every time Katevazo starts, so downloads keep working when sites change. The Check for Updates button and the Update yt-dlp command are gone.
• When the app is opened by a link from the browser extension, it finishes updating the download engine first and then opens the link.
• A banner above the page shows the update while it runs, and whether it installed a new version or could not check (for example when offline). Settings shows the engine version and its state.

Katevazo v0.5.3

Katevazo 0.5.3

Added

• Browser extension in Settings. Settings now lists the supported browsers installed on your computer (Chrome, Edge, Brave, Vivaldi, Arc, Chromium) with a button that opens the Katevazo extension's store page in that browser, and shows when the extension is already installed.
• The extension can tell whether Katevazo is installed. The app answers the extension's check and registers itself with Chrome, Edge, Brave, Chromium and Firefox each time it starts, so open it once after updating.

Notes

• Katevazo is in beta. The installers are not code-signed with a developer certificate yet, so Windows SmartScreen and macOS Gatekeeper may warn on first launch.
• If something does not work, please report it.

Katevazo v0.5.2

Katevazo 0.5.2

A fix for the macOS app.

Fixed

• macOS: yt-dlp failed to start with "Failed to load Python shared library". The ad hoc signing added in 0.5.1 made macOS reject the Python that yt-dlp unpacks at startup. The app now carries the entitlements it needs, and the release build runs yt-dlp, ffmpeg and ffprobe from inside the signed app to confirm they start.

Changed

• The browser extension (not part of the installers) adds a download icon after Share on Instagram reels and video posts from public accounts.

Notes

• Katevazo is in beta. The installers are not code-signed with a developer certificate yet, so Windows SmartScreen and macOS Gatekeeper may warn on first launch. See the README for how to open the Mac app.
• If downloads still fail on your Mac, please report it.

Katevazo 0.5.1

Katevazo 0.5.1

A fix for the macOS download.

Fixed

• macOS "damaged" message: the Mac app is now signed ad hoc, so Apple Silicon Macs no longer report the downloaded app as damaged. macOS still shows its "unidentified developer" warning because the app is not notarized yet. To open it, go to System Settings → Privacy & Security and choose Open Anyway. If it still says "damaged", run xattr -cr /Applications/Katevazo.app in Terminal once and open it again.

Notes

• Katevazo is in beta. The installers are not code-signed with a developer certificate yet, so Windows SmartScreen and macOS Gatekeeper may warn on first launch.
• The macOS signing change could not be tested on a Mac before release. If the app still will not open, please report it.

Katevazo 0.5.0

Katevazo 0.5.0

App polish: easier ways to add links, a tray, shortcuts, and eight languages.

New

• Drag and drop: drop a link, or a text file with one link per line, onto the window. Several links open as a batch with one shared format.
• Send from your browser: katevazo://download?url=… links work, and a small browser extension (in the extension/ folder) sends the page you are on to Katevazo.
• System tray: closing the window can keep Katevazo running in the background so downloads carry on. Press Ctrl+Shift+D (Cmd+Shift+D on a Mac) from any program to add the link on your clipboard.
• Command palette and shortcuts: Ctrl/Cmd+K opens the palette. Ctrl/Cmd+1–5 switch sections, Ctrl/Cmd+L enters a link and Ctrl/Cmd+, opens Settings.
• History: search and filter it, and download an item again.
• Welcome screen and What's new: shown on first launch and after an update.
• Languages: English (the default), Spanish, French, German, Portuguese, Italian, Japanese and Simplified Chinese. Change it in Settings.
• Accessibility: screen reader labels, a visible keyboard focus ring and announced status changes in the queue.

Notes

• Katevazo is in beta. The installers are not code-signed yet, so Windows SmartScreen and macOS Gatekeeper may warn on first launch.
• The tray, quick-add shortcut, katevazo:// links and the extension have been tested in pieces, not yet end to end in the installed app. The translations are unreviewed by native speakers. Please report anything odd.

Katevazo 0.4.0

Katevazo 0.4.0

Beyond YouTube: better support for other sites, live streams, and converting your own files.

New

• Site badges: a badge shows which site a link is from, with a note where a site needs something extra (Vimeo, Instagram and X usually want you signed in). Links from Vimeo, SoundCloud, X, Instagram, TikTok, Twitch, Facebook, Reddit and Dailymotion are offered when you copy them, and SoundCloud sets list like playlists.
• Record live streams: press Record on a live video and Stop when you are done. Streams and premieres that have not started yet are waited for and recorded. Keep Katevazo open meanwhile.
• Convert tab: change video or audio files on your computer to MP4, MKV, WebM, MP3, M4A, Opus, FLAC or WAV with the bundled ffmpeg. The originals are never changed.

Notes

• Katevazo is in beta. The installers are not code-signed yet, so Windows SmartScreen and macOS Gatekeeper may warn on first launch.
• Live recording and the Convert tab were tested in pieces, not yet end to end in the installed app. Please report anything odd.

Katevazo 0.3.0

Power-user features: more control over what is downloaded, when, and how.

New

• Trim: download only the part of a video between a start and end time.
• Downloads settings: choose how many downloads run at once and set a speed limit.
• Start later: schedule a download for a time you choose (Katevazo must be open then).
• Automatic retry: after a network error, Katevazo waits 5, 15 and 45 seconds, and so on, and tries again.
• SponsorBlock: mark sponsor segments as chapters, or cut them out.
• Download archive: skip videos you have already downloaded, with a button to forget them.
• Subscriptions: subscribe to a channel or playlist and new uploads download automatically every 30 minutes while the app is open.
• Proxy support and sign-in with browser cookies for age-restricted or members-only videos (Settings → Network).

Fixed

• Windows installer: the page title and subtitle now start right after the logo instead of leaving a wide gap.

Notes

• Installers are about 25 MB larger because ffprobe is now bundled for SponsorBlock.
• Katevazo is in beta. The installers are not code-signed yet, so Windows SmartScreen and macOS Gatekeeper may warn on first launch.

Katevazo 0.2.1

A polish release.

Changed

• The app name is now set in capitals in the Manrope typeface, with a Beta badge next to it.

Fixed

• Sidebar and in-app icons were uneven; the app now uses the Lucide icon set throughout.
• Dropdown lists (quality, container, codec and so on) showed blank choices in dark mode.
• The Windows installer header logo is aligned to the left edge.

Katevazo 0.2.0

Katevazo 0.2.0

A big feature release.

New

• Playlists and channels: tick the videos you want, or take them all.
• Formats: choose the container (MP4, MKV, WebM) and codec (H.264, VP9, AV1) for video, and the format (MP3, M4A, Opus, FLAC, WAV) and bitrate for audio.
• Subtitles: including auto-generated captions, saved as .srt or embedded in the video.
• Metadata: title, uploader, chapters and cover art embedded in downloaded files.
• Filename templates such as {uploader} - {title}, with sub-folders and a live preview.
• Clipboard offer when you copy a YouTube link (can be turned off in Settings).
• Notifications when a download finishes or fails in the background.
• Open a finished download, or show it in its folder, from the queue and History.

Fixed

• Bundles Deno so yt-dlp can solve YouTube's script challenges; without a JavaScript runtime some formats could go missing. Installers are larger as a result.
