 ### Formerly, EOCV-Sim was hosted on a [personal account repo](https://github.com/serivesmejia/EOCV-Sim/). Released prior to 3.0.0 can be found there for historic purposes.
 
+## [v4.0.0 - PaperVision is here !](https://github.com/deltacv/EOCV-Sim/releases/tag/v4.0.0)
+- This is the 30th release for EOCV-Sim
+    - Introducing PaperVision ! A tool bundled in the simulator that will make it even easier to work on your computer vision pipelines.
+    - Auto-accepts superaccess on trusted plugins, this reduces the UI clutter, especially for PaperVision
+    - Improved several dialogs, adds a better "create workspace" dialog & a welcome dialog that is shown when the sim is opened for the first time
+    - New modernized application icon
+    - @qwertychouskie made their first contribution: "macOS: Add application name, use system light/dark mode in titlebar" and "macOS: Use standard Settings & About entries in menu". Thank you !
