+
+As a general rule, if the tag information displayed by Tagbar is wrong (for
+example, a method doesn't show up or is in the wrong place) you should first
+try running ctags manually to see whether ctags reports the wrong information
+or whether that information is correct and Tagbar does something wrong. To run
+ctags manually execute the following command in a terminal:
+>
+	ctags -f - --format=2 --excmd=pattern --extra= --fields=nksaSmt myfile

+If you set the |g:tagbar_ctags_bin| variable you probably have to use the same
+value here instead of simply "ctags".
+
+If Tagbar doesn't seem to work at all, but you don't get any error messages,
+you can use Tagbar's debug mode to try to find the source of the problem (see
+|tagbar-commands| on how to invoke it). In that case you should especially pay
+attention to the reported file type and the ctags command line in the log
+file.
+
+
+  - jsctags has to be newer than 2011-01-06 since it needs the "-f" option to
+    work. Also, the output of jsctags seems to be a bit unreliable at the
+    moment (especially regarding line numbers), so if you notice some strange

 8. History						*tagbar-history*
 
+2.3 (2011-12-24)
+    - Add a convenience function that allows more flexible ways to
+      automatically open Tagbar.
+    - Replace option tagbar_usearrows with tagbar_iconchars to allow custom
+      characters to be specified. This helps with fonts that don't display the
+      default characters properly.
+    - Remove the need to provide the complete jsctags configuration if jsctags
+      is not found in $PATH, now only the concrete path has to be specified.
+    - Add debugging functionality.
+
+2.2 (2011-11-26)
+    - Small incompatible change: TagbarOpen now doesn't jump to the Tagbar
+      window anymore if it is already open. Use "TagbarOpen j" instead or see
+      its documentation for more options.
+    - Tags inside of scopes now have a header displaying their "kind".
+    - The Tagbar contents are now immediately updated on save for files
+      smaller than a configurable size.
+    - Tagbar can now be configured to jump to a tag with only a single-click
+      instead of a double-click.
+    - Most of the script has been moved to the |autoload| directory, so Vim
+      startup should be faster (thanks to Kien N).
+    - Jumping to tags should work most of the time even if the file has been
+      modified and not saved.
+    - If Ctags has been installed into the default location using Homebrew or

+    - Fixed a bug with the handling of subtypes like "python.django"
+    - If a session got saved with Tagbar open it now gets restored properly
+    - Locally reset foldmethod/foldexpr in case foldexpr got set to something
