Yes, if you need V4 for Blender 2.93 to 4.5.4, you'll automatically see a 70% discount when you visit the V4 product page.  This doesn't apply if Turbo X was obtained through a bundle.

Turbo Tools X comes with a lifetime license, so you can use it indefinitely with no further purchases required. To keep the addon actively maintained, your purchase includes 12 months of updates. After that, you’ll have the option to extend update access in 12‑month maintenance blocks for a small fee. This model ensures Turbo Tools X can continue to evolve long‑term, without relying solely on new sales. It gives existing users confidence that their investment will remain supported and up to date, even as sales naturally slow over time.

Yes! Anyone who purchased Turbo Tools V4 before the release of Turbo X, will receive 70% off Turbo Tools X using code: ttxloyaltydiscount

Updating Turbo Tools V4 to support Blender 5 wasn’t possible without breaking backward compatibility with earlier Blender versions that many users still rely on. To ensure those users aren’t left behind, Turbo Tools V4 will continue to receive updates and support until Blender 4.5.4 LTS retires in 2027. Creating Turbo Tools X as a separate product avoids the challenge of maintaining two vastly different 8,000+ line codebases within a single addon. This approach allows V4 to remain a reliable option for users on older Blender versions, while X evolves alongside Blender 5 and beyond. Launching Turbo Tools X as its own product also enables a sustainable update policy. This ensures the addon can continue to grow and remain actively maintained even as new sales naturally slow over time. Existing V4 customers benefit from generous upgrade discounts, making the transition fair and accessible.
