2026.3.0-beta3

This is the third beta release in the 2026.3.0 series. This release contains many new features and fixes compared to the previous beta.

Mainly, the ability to toggle separately downloading audio and video media immediately and ignoring super resolutions from YouTube AI. Parabolic is now built and deployed using C#'s NativeAOT technology. This turns C# into machine code as opposed to relying on the JIT compiler. You should now experience faster launch times and a faster experience overall. We are still evaluating the compatibility of all of our libraries and code with NativeAOT, so issues and crashes are expected. Please report them as you find.

In the bug world, we fixed issues with running the new macOS version of Parabolic, download errors, and other minor issues.

Thank you all for your continued support and testing of the beta ❤️! V2026.3.0 is gonna be huge 🚀!

** NEW ** macOS App

We have introduced a new macOS app that is built using the GNOME (GTK/libadwaita) version of Parabolic. It bundles all dependencies including yt-dlp, aria2c, ffmpeg and deno - alongside GTK itself.

Issues are expected as I do not have a Mac myself and rely on feedback and information from users in the community to test the app for me. Thank you!

** NEW ** Windows Portable App

We have re-introduced a portable Windows build of Parabolic. This build works a little differently than previous versions in that it's the same exe as the installer version but requires the --portable flag be passed to the .exe file for it to run in portable mode.

For convenience, we have added a .bat file to the portable download that can be ran that does it for you already. Alternatively, once the portable version is extracted to the location of your choice, you can create a shortcut for the .exe and specify the --portable flag in the arguments of the shortcut's properties.
