+## Structure Change (happening soon)
+> [!NOTE]
+> Please note that Aurelia-Slickgrid (and all other supported frameworks) will soon be moved under the [Slickgrid-Universal](https://github.com/ghiscoding/slickgrid-universal) project.
+> This will happen in the next major version, which is expected in Q2 of 2025. The installation remains the same `npm install aurelia-slickgrid`, it's just the project that will be moved into a central location (easier to maintain).

 ### Brief introduction
 One of the best JavasSript data grid [SlickGrid](https://github.com/mleibman/SlickGrid), which was originally developed by @mleibman, is now available to the Aurelia world. SlickGrid beats most other data grids in terms of features, customizability & performance (running smoothly with even a million rows). Aurelia-Slickgrid is a wrapper on top of [Slickgrid-Universal](https://github.com/ghiscoding/slickgrid-universal/) (which is a dependency), in the early beginning we used the `6pac/SlickGrid` fork but that was dropped in >=[v7.0](https://github.com/ghiscoding/aurelia-slickgrid/releases/tag/v7.0.3) since Slickgrid-Universal is now a standalone project. SlickGrid was also recently rewritten with browser native code (no more ~jQuery~ 🎉).
