+### 4.6
+
+- fix for middle mouse button not working
+- fix of logo overlay using a huge amount of memory (thx for the [ghacks article](https://www.ghacks.net/2019/07/05/a-look-at-mpv-net-a-mpv-frontend-with-everything-integration/))
+- fix config dialog showing a message about app restart without reason
+- when multiple files are selected in Windows File Explorer and enter is
+  pressed, the files are opened as selected, the order is random though
+  because Explorer starts multiple mpv.net processes concurrently
+- libmpv was updated to shinchiro 2019-06-30
+- the [mpv.conf defaults](https://github.com/stax76/mpv.net/blob/master/mpv.net/Resources/mpvConf.txt) were changed to show a larger OSC
+- in case a file is opened that has a aspect ratio smaller then 1.2 then
+  the window size will use a aspect ratio of 1.8
+- new JavaScript script osc-visibility.js included in the distribution
+  under startup\scripts. It sets the OSC to be always on for audio files
+  and auto for non audio files
+
 ### 4.5
