+2.14.3
+    Thanks to tpope for the following:
+    - use relative paths when doing edit commands if possible (useful if you
+      have %f on your statusline for example)
+    - allow relative paths for :NERDTree commands, eg ":NERDTree ../foo"
+    - fix a bug where the script used the directory of the current buffer
+      instead of vims cwd for the :NERDTree command
+    - bugfix for read only node highlighting
+
 2.14.2
     - when opening a file (with 'o' or double click) dont split the window
       unless we absolutely have to. This should make the script work better
