## Default branch

When you create a new [project](../../index.md), GitLab sets `master` as the default
branch for your project. You can choose another branch to be your project's
default under your project's **Settings > General**.

The default branch is the branch affected by the
[issue closing pattern](../../issues/automatic_issue_closing.md),
which means that _an issue will be closed when a merge request is merged to
the **default branch**_.

The default branch is also protected against accidental deletion. Read through
the documentation on [protected branches](../../protected_branches.md#protected-branches)
to learn more.

## Delete merged branches

> [Introduced][ce-6449] in GitLab 8.14.

![Delete merged branches](img/delete_merged_branches.png)

This feature allows merged branches to be deleted in bulk. Only branches that
have been merged and [are not protected][protected] will be deleted as part of
this operation.

It's particularly useful to clean up old branches that were not deleted
automatically when a merge request was merged.
