-## Diagram (3.0.0) - 2024-02-24
+## Diagrams (3.0.3) - 2024-12-03
+
+### Added
+
+- Support for .NET 9 (thanks to @[PanayiotisTheodosiou](https://github.com/PanayiotisTheodosiou))
+- `registerDefaultBehaviors` argument to `BlazorDiagram` constructor, it's `true` by default and can be disabled if you want to control what behaviors are added and their order.
+
+### Changed
+
+- Make `DiagramCanvas` await un-subscription to resizes subscription (thanks to @[toluwtglobal](https://github.com/toluwtglobal))
+
+### Fixed
+
+- Exception thrown when `node.Visible` was `false` from the creation and the library was trying to observe its resizes when the element won't exist (fixes #476).
+
+### Removed
+
+- gzip versions of assets, it was causing an issue with .NET 9 (fixes #471, thanks a lot @[robertmclaws](https://github.com/robertmclaws))
+
+## Diagram (3.0.2) - 2024-02-24
