+If invalid bookmarks are detected, the script will issue an error message and

+
+These bookmarks will still be stored in the bookmarks file (see
+|NERDTreeBookmarksFile|), down the bottom. There will always be a blank line
+after the valid bookmarks but before the invalid ones.
+
+Each line in the bookmarks file represents one bookmark. The proper format is:
+<bookmark name><space><full path to the bookmark location>

+After you have corrected any invalid bookmarks, either restart vim, or go
+:ReadBookmarks from the NERD tree window.

+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.
