 ### Changelog
 
+### 3.1 (2019-04-23)
+
+- the Tracks and Chapters menu are now only added if default bindings exist and
+  it's now possible to move the chapters menu to the top level by editing input.conf
+- mpvnet supports now like mpv a portable settings directory. If a directory named portable_config
+  next to the mpvnet.exe exists, all config will be loaded or written in this directory.
+- there is now a portable download in 7zip format.
+
 ### 3.0 (2019-04-20)
 
 - the history feature logs now only files that were opened longer than 90 seconds
