For curators: Collection metadata now persists when cloning, and unowned collections no longer show up in the workshop tab.

For users: We've sorted out mod installation failures prerequisite checks, and collection install tracking now correctly reports installed mods. VR variants of Bethesda games can update and install mods again. We've also addressed an issue where archives could be incorrectly removed, improved how shared mods are handled across collections, and resolved corrupt downloads. Plus a handful of crash fixes.

What's New

This one's been cooking! We're excited to bring you speed and reliability improvements across the board, a new way to browse Collections, and important security and platform updates under the hood.

🚀 Speed & Efficiency

We've overhauled the installation pipeline. Collection installs are around 50% faster, turning what used to take 15 minutes into 5-6 minutes. Downloads are faster too, with up to 10 mods downloading simultaneously and installation happening in the background while your remaining downloads finish. Failed downloads now automatically retry, meaning fewer manual restarts. All users will notice a significant increase in speed and reliability with fewer stalls and errors.

⚡ Integrated Collection Browsing

You can now browse collections directly in Vortex, with Premium users being able to take advantage of our single click install, installing 100’s of curated mods faster than ever before.

🛠️ Quality of Life

We've tidied up the notification system with new Toast-style notifications that stay out of your way, meaning less distractions while you mod. Under the hood, we've upgraded to Electron 37 and .NET 9, bringing massive improvements to the stability of the core of Vortex, as well as specific improvements for some of our most popular games like Fallout New Vegas and Stardew Valley.

Take a look below for the technical details. We hope you enjoy and let us know what you think with the new feedback form which can be found in the top nav menu.
