#### 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
