+
+Please note that PowerShell don't allow assigning to events and mpv.net uses as workaround the script filename.
+
+```
+$position = [mp]::get_property_number("time-pos");
+[mp]::commandv("show-text", $position.ToString() + " seconds")
+```
+
 ### Changes
 
+### 1.3
+
+- besides Lua/JavaScript/C#/Python there is now PowerShell supported as fifth scripting language
+
+- in case there isn't yet a mpv.conf file mpv.net creates the file with certain default settings that were previously set on every mpv.net start. This was changed to provide transparency on which settings mpv.net uses. These default settings can be seen here: https://github.com/stax76/mpv.net/blob/master/mpv.net/Resources/mpv.conf.txt
+
+### 1.2
+
+- a thread synchonisation bug which caused the shutdown to be delayed or frozen was fixed, it also caused the Shutdown event not to fire which caused the rating plugin not to work
+
 ### 1.1
 
 - added support for Python scripting via IronPython
