We are preparing ReoGrid V5, the next generation of our .NET spreadsheet component — and, alongside it, a new licensing and pricing model that takes effect on August 19, 2026.
Update — August 19, 2026: V5 is out, and everything below is now published. See what’s new in V5 for the release itself, pricing for the ReoGrid One licensing model, running V4 and V5 side by side for what a single license covers, and the migration guide for moving an existing project across.
ReoGrid V5 — rebuilt from the core
V5 is an entirely new generation. The core has been rebuilt around a fully virtualized architecture that works with only the data actually needed.
What that means in practice:
- Faster in both WinForms and WPF. The speed-up is in the engine both platforms share, so both benefit equally.
- Substantially lower memory use, particularly with large workbooks — the workloads where the old architecture cost the most.
- A new platform: Avalonia. In addition to WinForms and WPF, V5 introduces support for Avalonia, bringing ReoGrid to cross-platform .NET desktop applications.
Both the migration guide and the V4 → V5 differences are published as part of the V5 documentation.
A new licensing model from August 19, 2026
Together with the V5 release, we are moving to a new licensing and pricing model on August 19, 2026.
That model is now live. The .NET editions are a single product line — ReoGrid One — sold as two SKUs, and a license is version-independent: one purchase covers both V4 and V5, with the same key. See pricing for the current figures and what each edition includes.
ReoGrid V4 will continue to be sold and supported. It stays available alongside V5, and the same license covers it — see running V4 and V5 side by side.
