-5.0.0
-    - Refactor the code significantly:
-        * Break the classes out into their own files.
-        * Make the majority of the code OO - previously large parts were
-          effectively a tangle of "global" methods.
-    - Add an API to assign flags to nodes. This allows VCS plugins like
-      https://github.com/Xuyuanp/nerdtree-git-plugin to exist. Thanks to
-      Xuyuanp for helping design/test/build said API.
-    - add 'scope' argument to the key map API see :help NERDTreeAddKeyMap()
-    - add magic [[dir]] and [[file]] flags to NERDTreeIgnore
-    - add support for custom path filters. See :help NERDTreeAddPathFilter()
-    - add path listener API. See :help NERDTreePathListenerAPI.
-    - expand the fs menu functionality to list file properties (PhilRunninger,
-      apbarrero, JESii)
-    - make bookmarks work with `~` home shortcuts (hiberabyss)
-    - show OSX specific fsmenu options in regular vim on mac (evindor)
-    - make dir arrow icons configurable (PickRelated)
-    - optimise node sorting performance when opening large dirs (vtsang)
-    - make the root note render prettier by truncating it at a path slash (gcmt)
-    - remove NERDChristmasTree option - its always christmas now
-    - add "cascade" open and closing for dirs containing only another single
-      dir. See :help NERDTreeCascadeOpenSingleChildDir (pendulm)

-
-4.1.0
-    features:
-    - NERDTreeFind to reveal the node for the current buffer in the tree,
-      see |NERDTreeFind|. This effectively merges the FindInNERDTree plugin (by

-      to Guillaume Duranceau for the patch. See :help NERDTree-A for details.
-
-    - fix a bug where secondary nerd trees (netrw hijacked trees) and
-      NERDTreeQuitOnOpen didnt play nicely, thanks to Curtis Harvey.
-    - fix a bug where the script ignored directories whose name ended in a dot,
-      thanks to Aggelos Orfanakos for the patch.
-    - fix a bug when using the x mapping on the tree root, thanks to Bryan
-      Venteicher for the patch.
-    - fix a bug where the cursor position/window size of the nerd tree buffer
-      wasnt being stored on closing the window, thanks to Richard Hart.
-    - fix a bug where NERDTreeMirror would mirror the wrong tree
-
-3.1.1
-    - fix a bug where a non-listed no-name buffer was getting created every
-      time the tree windows was created, thanks to Derek Wyatt and owen1
-    - make <CR> behave the same as the 'o' mapping
-    - some helptag fixes in the doc, thanks strull

-      NERDTreeChDirMode==2 (thanks to Lucas S. Buchala)
-    - add -bar to all the nerd tree :commands so they can chain with other
-      :commands (thanks to tpope)
-    - fix bugs when ignorecase was set (thanks to nach)
-    - fix a bug with the relative path code (thanks to nach)
-    - fix a bug where doing a :cd would cause :NERDTreeToggle to fail (thanks nach)

+
+#### 5.0.0
+- Refactor the code significantly:
+    * Break the classes out into their own files.
+    * Make the majority of the code OO - previously large parts were effectively a tangle of "global" methods.
+- Add an API to assign flags to nodes. This allows VCS plugins like https://github.com/Xuyuanp/nerdtree-git-plugin to exist. Thanks to **Xuyuanp** for helping design/test/build said API.
+- add `scope` argument to the key map API see :help NERDTreeAddKeyMap()
+- add magic [[dir]] and [[file]] flags to NERDTreeIgnore
+- add support for custom path filters. See :help NERDTreeAddPathFilter()
+- add path listener API. See :help NERDTreePathListenerAPI.
+- expand the fs menu functionality to list file properties (PhilRunninger, apbarrero, JESii)
+- make bookmarks work with `~` home shortcuts (hiberabyss)
+- show OSX specific fsmenu options in regular vim on mac (evindor)
+- make dir arrow icons configurable (PickRelated)
+- optimise node sorting performance when opening large dirs (vtsang)
+- make the root note render prettier by truncating it at a path slash (gcmt)
+- remove NERDChristmasTree option - its always christmas now
+- add "cascade" open and closing for dirs containing only another single dir. See :help NERDTreeCascadeOpenSingleChildDir (pendulm)
+- Many other fixes, doc updates and contributions from: **actionshrimp**, **agrussellknives**, **alvan**, **AndrewRadev**, **cperl82** (*many small fixes*), **devmanhinton**, **egalpin**, **franksort**, **gastropoda**, **handcraftedbits**, **kelaban**, **lucascaton**, **mixvin**, **pendulm**, **SchDen**, **shanesmith**, **staeff**, **stephenprater**, **toiffel**, **Twinside**, **WoLpH**, **xiaodili**, **zhangoose**
+
+#### 4.2.0
+- Add NERDTreeDirArrows option to make the UI use pretty arrow chars instead of the old +~| chars to define the tree structure (sickill)
+- shift the syntax highlighting out into its own syntax file (gnap)
+- add some mac specific options to the filesystem menu - for macvim only (andersonfreitas)
+- Add NERDTreeMinimalUI option to remove some non functional parts of the nerdtree ui (camthompson)
+- tweak the behaviour of :NERDTreeFind - see :help :NERDTreeFind for the new behaviour (benjamingeiger)
+- if no name is given to :Bookmark, make it default to the name of the target file/dir (minyoung)
+- use `file` completion when doing copying, create, and move operations (EvanDotPro)
+- lots of misc bug fixes from: **AndrewRadev**, **Bogdanov**, **camthompson**, **kml**, **mathias**, **paddyoloughlin**, **scottstvnsn**, **sdewald**, **Vitaly**, **wycats**, me RAWR!
+
+#### 4.1.0
+- features:
+    - NERDTreeFind to reveal the node for the current buffer in the tree, see `|NERDTreeFind|`. This effectively merges the FindInNERDTree plugin (by **Doug McInnes**) into the script.
+    - make NERDTreeQuitOnOpen apply to the t/T keymaps too. Thanks to **Stefan Ritter** and **Rémi Prévost**.
+    - truncate the root node if wider than the tree window. Thanks to **Victor Gonzalez**.
+
+- bugfixes:
+    - really fix window state restoring
+    - fix some win32 path escaping issues. Thanks to **Stephan Baumeister**, **Ricky**, **jfilip1024**, and **Chris Chambers**.
+
+#### 4.0.0
+- add a new programmable menu system (see `:help NERDTreeMenu`).
+- add new APIs to add menus/menu-items to the menu system as well as custom key mappings to the NERD tree buffer (see `:help NERDTreeAPI`).
+- removed the old API functions
+- added a mapping to maximize/restore the size of nerd tree window, thanks to Guillaume Duranceau for the patch. See :help NERDTree-A for details.
+- fix a bug where secondary nerd trees (netrw hijacked trees) and NERDTreeQuitOnOpen didnt play nicely, thanks to **Curtis Harvey**.
+- fix a bug where the script ignored directories whose name ended in a dot, thanks to **Aggelos Orfanakos** for the patch.
+- fix a bug when using the x mapping on the tree root, thanks to **Bryan Venteicher** for the patch.
+- fix a bug where the cursor position/window size of the nerd tree buffer wasnt being stored on closing the window, thanks to **Richard Hart**.
+- fix a bug where NERDTreeMirror would mirror the wrong tree
+
+#### 3.1.1
+- fix a bug where a non-listed no-name buffer was getting created every time the tree windows was created, thanks to **Derek Wyatt** and **owen1**
+- make `<CR>` behave the same as the `o` mapping
+- some helptag fixes in the doc, thanks **strull**.
+- fix a bug when using `:set nohidden` and opening a file where the previous buf was modified. Thanks **iElectric**.
+- other minor fixes
+
+#### 3.1.0
+- New features:
+    - add mappings to open files in a vsplit, see `:help NERDTree-s` and `:help NERDTree-gs`
+    - make the statusline for the nerd tree window default to something hopefully more useful. See `:help 'NERDTreeStatusline'`
+- Bugfixes:
+    - make the hijack netrw functionality work when vim is started with `vim <some dir>` (thanks to **Alf Mikula** for the patch).
+    - fix a bug where the CWD wasnt being changed for some operations even when NERDTreeChDirMode==2 (thanks to **Lucas S. Buchala**)
+    - add -bar to all the nerd tree :commands so they can chain with other :commands (thanks to **tpope**)
+    - fix bugs when ignorecase was set (thanks to **nach**)
+    - fix a bug with the relative path code (thanks to **nach**)
+    - fix a bug where doing a `:cd` would cause `:NERDTreeToggle` to fail (thanks **nach**)
+
+
+#### 3.0.1
+- Bugfixes:
+    - fix bugs with :NERDTreeToggle and :NERDTreeMirror when `'hidden'` was not set
+    - fix a bug where `:NERDTree <path>` would fail if `<path>` was relative and didnt start with a `./` or `../`  Thanks to **James Kanze**.
+    - make the `q` mapping work with secondary (`:e <dir>`  style) trees, thanks to **jamessan**
+    - fix a bunch of small bugs with secondary trees
+- More insane refactoring.
+
+#### 3.0.0
+- hijack netrw so that doing an `:edit <directory>`  will put a NERD tree in the window rather than a netrw browser. See :help 'NERDTreeHijackNetrw'
+- allow sharing of trees across tabs, see `:help :NERDTreeMirror`
+- remove "top" and "bottom" as valid settings for NERDTreeWinPos
+- change the `'<tab>'` mapping to `'i'`
+- change the `'H'` mapping to `'I'`
+- lots of refactoring
