 ### Updated viewer handedness ✋
 
@@ -38,3 +54,69 @@ implemented workarounds in your code (such as setting the z-scale to a negative
 number), now is a good time to undo the workarounds for newer versions of
 napari! If you run into any issues please get in touch [on GitHub

+
+### Polygons with holes
+
+Finally, napari is now able to display polygons with holes in them, which starts to open it up for use with mapping data, among other things. Implement polygon with holes in compiled triangulation (#7566)
+
+### Addition of a command palette
+
+The command palette is a new feature that allows you to search for and execute commands in napari. This is a powerful feature that allows you to quickly access and execute commands without having to navigate through the menus. Implement command palette widget (#5483)
+
+### Transition to npe2 plugin engine
+
+npe1 plugins will be automatically converted to npe2 by default (this may break some features if they rely on import-time behaviour).
+npe1 plugins will now be automatically converted to npe2 by default (with a warning), which should not change much but it will break plugins that rely on being imported at launch to modify viewer behaviour. You will be able to turn off this automatic conversion in the settings, but this will go away in 0.7.0 (planned for July),
+so this is your opportunity to work with plugin authors to migrate to npe2.
+
+## Improved modules and features
+
+### Napari core improvements 🧠
+
+- Implement polygon with holes in compiled triangulation (#7566)
+- Add Grid Mode Spacing to change distance between layers (#7597)
+- Add API to Camera model to flip axes (#7663)
+- Flip z axis on 3D camera to default to right-handed frame (#7488 redux) (#7554)
+
+### GUI improvements 🎨
+
+- Implement command palette widget (#5483)
+- Show layer status for all visible layers (#7673)
+- Enable creation of custom linear colormaps in layer controls (#7600)
+- Change ndisplay button to toggle-like to increase discoverability (#7608)
+- Expose additional Camera parameters in GUI with 3D popup widget (#7626)
+- Add right-click indicator to 3D, Roll, Grid, and Square push buttons (#7556)
+- Fix issues displaying polygons with holes in Shapes (#6654)
+
+### Plugins 
+
+Turn on npe2 adaptor by default and add warning (#7627)

+
+### Performance and maintainability
+
+- Pydantic 2.0+ will be required. Remove pydantic v1 compatibility layer, depend on pydantic>=2.2 (#7589) We are requiring Pydantic version 2 and higher. Supporting Pydantic 1 and 2 together was a lot of effort, but by now most plugins and libraries using Pydantic are at version 2, which does bring significant speed and functionality advantages. If you know a library or plugin you use with napari and that is still strictly on Pydantic 1.x, please let us know!
+- Python 3.10+ will be required. Update configuration to drop python 3.9 and add python 3.13 (#7603). We are dropping Python 3.9 support. This is slightly earlier than Python 3.9's EOL date (October 2025), but we are still supporting Python 3.10 which is past its recommended window from SPEC0. The bundle follows SPEC0 strictly and so uses Python 3.11. We hope that serves most if not all of our user community!
