+# MSU Scripter 5.0.0
+
+Release 5.0.0 introduces some major overhauls to the MSU Scripter in order to make the experience better for users.
+
+## Updated UI
+
+The UI has been completely redesigned to allow you to make things easier and more streamlined.
+
+### Main Starting Window
+

+
+The main starting window has been redone to have tabs for the creating new projects, opening projects, and changing settings.
+The first time launching, it will default to the new project tab, which now allows you to populate additional fields before creating the MSU project than before. 
+When launching the MSU Scripter after creating a project, it will default to the open project tab.
+
+### MSU Project Window

+
+After opening a project, the list of all tracks and songs is now displayed on the left. 
+Using this left panel, you can select the track you want to view, add songs to tracks, and even move songs around between different tracks.
+You can easily search for specific tracks as well as customize the view to show additional icons to easily see the status of the project.
+
+### Basic vs Advanced Song Views

+
+When editing the details of a song, you can choose to either use the basic view with integrated PyMusicLooper that will only show the most commonly edited fields,
+or you can use the advanced view which has all MsuPcm++ fields accessible. The advanced view has a panel similar to the track panel that allows you to add, copy,
+and move sub tracks and sub channels easily. By default the MSU Scripter will ask each time which view you want to use, but you can select a default view if desired.
+
+The buttons for playing the song and the audio controls are now always accessible at the bottom when viewing a song as well.
