+2.xx.xx
+    - dont clobber &cpo. Thanks to godlygeek for the bug report.
+
+2.14.0
+    - fix a bug where the <c-w>o mapping  would cause the tree window to be
+      incorrectly sized when reopened.
+    - add keymapping to delete bookmarks from the bookmarks table, see
+      :help NERDTree-D
+    - lots of refactoring
+2.13.0
+    - make NERDTreeChDir option default to 0 (i.e. never change vims current
+      working dir by default)
+    - when moving/deleting nodes with the filesystem menu, move/delete any
+      associated bookmarks
+    - make the t/T on directory nodes open a fresh NERD tree for the selected
+      dir in a new tab, rather than a netrw.
+    - place the cursor at the top of the bookmarks table when opening it with B
+    - make NERDTreeQuitOnOpen option work with the g<tab> and go mappings,
+      thanks to Maxim Kim for the bug report
+    - change how invalid bookmarks are handled. Now they are not deleted. If a
+      bookmark is malformed (in the bookmarks file) or points to an
+      invalid/nonexisting location then print an error and place the offending
+      bookmarks at the bottom of the bookmarks file. See :help
+      |NERDTreeInvalidBookmarks| for info. Thanks to Zhang Shuhan for the
+      suggestion and the testing.
+    - fix a bug with the 'o' mapping that occurred when opening a new buffer
+      for a file whose name was a substring of an already open file. Thanks to
+      Charlton Wang for the report.
+    - stop the script from going into an infinite loop when it tries to cache
+      a named pipe. Thanks to Charlton Wang for the report.
+
+2.12.0
+    - added a UI for bookmarks. See :help NERDTreeBookmarkTable for details.
+      Thanks to Zhang Shuhan for testing and bug reports.
+    - relaxed the restrictions on bookmark names, now the only restriction is
+      that they cant contain spaces. This allows for e.g. Chinese bookmark
+      names. Thanks to Zhang Shuhan for the suggestion.
+    - combined the NERDTreeWinPos and NERDTreeSplitVertical options. See :help
+      NERDTreeWinPos.
+    - applied a patch from Matan Nassau to add the NERDTreeQuitOnOpen option
+      which closes the tree window after opening a file. See :help
+      NERDTreeQuitOnOpen.
+    - optimised the nerd tree rendering. Now it takes just over 1/3 of the
+      time it previously took to render.
+    - now the tree filter mappings toggle the filters "per tree" rather than
+      globally. The global filter variables are used to set the initial filter
+      settings for each new NERD tree.
+    - fix to window resizing when opening a file when NERD tree is the only
+      window open
+    - other fixes
