### New Version Info

#### Author's Instructions
- [ ] Derive a new `MAJOR.MINOR.PATCH` version number. Increment the:
    - `MAJOR` version when you make incompatible API changes
    - `MINOR` version when you add functionality in a backwards-compatible manner
    - `PATCH` version when you make backwards-compatible bug fixes
- [ ] Update [CHANGELOG.md](https://github.com/scrooloose/nerdtree/blob/master/CHANGELOG.md), following the established pattern.
#### Collaborator's Instructions
- [ ] Review [CHANGELOG.md](https://github.com/scrooloose/nerdtree/blob/master/CHANGELOG.md), suggesting a different version number if necessary.
- [ ] After merging, tag the commit using these (Mac-compatible) bash commands:
    ```bash
    git checkout master
    git pull
    sed -n "$(grep -n -m2 '####' CHANGELOG.md | cut -f1 -d: | sed 'N;s/\n/,/')p" CHANGELOG.md | sed '$d'
    git tag -a $(read -p "Tag Name: " tag;echo $tag) -m"$(git show --quiet --pretty=%s)";git push origin --tags
    ```
