 ### 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

 ### Can NERDTree access remote files via scp or ftp?
 
 Short answer: No, and there are no plans to add that functionality. However, Vim ships with a plugin that does just that. It's called netrw, and by adding the following lines to your `.vimrc`, you can use it to open files over the `scp:`, `ftp:`, or other protocols, while still using NERDTree for all local files. The function seamlessly makes the decision to open NERDTree or netrw, and other supported protocols can be added to the regular expression.
