GitHub Enterprise 2.8 is now available with code review, project management tools, and Jupyter notebook rendering

GitHub Enterprise 2.8 adds power and versatility directly into your workflow with Reviews for more streamlined code review and discussion, Projects to bring development-centric project management into GitHub, and Jupyter notebook rendering to visualize data.

Code better with Reviews

Reviews help you build flexible code review workflows into your pull requests, streamlining conversations, reducing notifications, and adding more clarity to discussions. You can comment on specific lines of code, formally “approve” or “request changes” to pull requests, batch comments, and have multiple conversations per line. These initial improvements are only the first step of a much greater roadmap toward faster, friendlier code reviews.

Organize projects while staying close to your code

With Projects, you can manage work directly from your GitHub repositories. Create task cards from pull requests, issues, or notes and drag and drop them into categorized columns. You can use categories like “In-progress”, “Done”, “Never going to happen”, or any other framework your team prefers. Move the cards within a column to prioritize them or from one column to another as your work progresses. And with notes, you can capture every early idea that comes up as part of your standup or team sync, without polluting your list of issues.

Visualize data-driven workflows with Jupyter Notebook rendering

Producing and sharing data on GitHub is a common challenge for researchers and data scientists. Jupyter notebooks make it easy to capture those data-driven workflows that combine code, equations, text, and visualizations. And now they render in all your GitHub repositories.

Share your story as a developer

This release takes the contribution graph to new heights with your GitHub timeline—a snapshot of your most important triumphs and contributions. Curate and showcase your defining moments, from pinned repositories that highlight your best work to a profile timeline that chronicles important milestones in your career.

Amp up administrator visibility and security enforcement

GitHub Enterprise 2.8 gives administrators more ways to enforce security policies, understand and improve performance, and get developers the support they need. Site admins can now enforce the use of two-factor authentication at the organization level, efficiently visualize LDAP authentication-related problems—like polling, repeated failed login attempts, and slow servers—and direct users to their support website throughout the appliance.

Upgrade to GitHub Enterprise 2.8 today to start using these new features and keep improving the way your team works. You can also check out the release notes to see what else is new or enable update checks to automatically check for the latest releases of GitHub Enterprise.

GitHub Enterprise 2.7 is now available with enhanced security and more powerful APIs

A new release of GitHub Enterprise is now available with improvements for developers and administrators alike. With GitHub Enterprise 2.7, we’re introducing GPG signature verification — a new way for teams to protect their projects and definitively know who authored a commit. The release also includes several API previews to help you create integrations that enforce customized policies and fit your workflows.

Continuing the effort to make collaboration seamless, GitHub Enterprise 2.7 adds new tools for developers, designers, product managers, and team leads to work together and communicate. Updates include the ability to assign multiple people to an issue, reorder task lists, and labels to indicate whether an issue or pull request comment has been edited.

Ready to upgrade? Download GitHub Enterprise 2.7.

Know that code comes from a verified source

When building software with a large or distributed team, it’s important to validate that commits and tags are coming from an identified source. Now you can definitively know who authored code or pushed a change to production with GPG signature verification.

gpg sign your git commits on GitHub

When you view a signed commit or tag, you can see a badge indicating if the signature can be verified using any of the contributor’s GPG keys uploaded to your GitHub Enterprise appliance. This makes it easy to see if a signature is from a verified key that GitHub trusts. To learn more about how to generate a GPG key and start signing your work, check out our documentation on GPG.

Fine tune the way you work

You know your workflow best. To help you work the way you want to, this update includes a series of significant API updates that allow you to further customize GitHub Enterprise, build integrations, and use automation to enforce policies. Check out the documentation for the pre-receive hooks API, protected branches API, reactions API, locking and unlocking issues via the API, and squashing pull requests in the API.

The release also adds ways for you to streamline your development process:

  • Make it a group effort. Assign multiple users to tasks, adding up to 10 people to a given issue or pull request.
  • Easily prioritize task lists without editing markdown. Drag and drop checklist items to position them higher or lower in a list.
  • Know when comments have been edited. When you or your coworker makes an edit, you’ll see an “edited” badge in the comment header.

Upgrade today

Upgrade today so you and your team can start using GPG signature verification and keep improving the way you work. You can also check out the release notes to see what else is new or enable update checks to automatically check for the latest releases of GitHub Enterprise.

Migrate your repositories using ghe-migrator

Sometimes customers find themselves needing the unique advantages of GitHub Enterprise and decide to move their private repositories there. Now it’s easier than ever to move repositories to GitHub Enterprise from or instances of GitHub Enterprise using ghe-migrator. In fact, it’s helped more than 120 organizations migrate more than 2,500 repositories in the last nine months alone.

The advantage of using ghe-migrator instead of manually cloning and pushing repositories is that it includes GitHub data with the repository, including its issues, pull requests, user data, and wiki.

Completed migration to GitHub Enterprise

Before getting started

First off, using the ghe-migrator utility requires GitHub Enterprise version 2.3 or greater. If your version is not recent enough to use ghe-migrator, please refer to the documentation for upgrading GitHub Enterprise. The migration process also requires two other servers to be running. You will need a unix-based server running GitHub Enterprise’s backup-utils and another instance of GitHub Enterprise (running the same version as your production instance) to perform dry runs of the migration.

If you are using authentication mechanisms such as LDAP or SAML, or want to enforce user naming conventions, you should also compile a CSV of username mappings. The CSV should look like this (substituting with the URL of your GitHub Enterprise instance):


Where source_url refers to the URL of a given user, and target_url contains the desired username in GitHub Enterprise. Use the map action if the target user already exists on GitHub Enterprise, and rename if the user needs to be created. You can learn more about custom mappings in the GitHub Enterprise Documentation.

All of the commands below will run directly on the GitHub Enterprise instance. Start by logging in to the administrative shell using SSH.

Note: All of the steps below should be performed on the sandbox instance of GitHub Enterprise before running them on the production instance.

You will need a personal access token from with the admin:org permission selected. The token must be generated by an owner of the organization that contains the repositories you wish to migrate. Once obtained, set an environment variable on your GitHub Enterprise instance for easy reference.

export GITHUB_TOKEN=[your personal access token]

You will also need a personal access token from your GitHub Enterprise instance from a site admin user. This will be the user performing the import to GitHub Enterprise.

It is important to make frequent backups of your GitHub Enterprise instance using backup-utils in between each step of the migration process. This affords flexibility in trying different migration strategies.

Exporting from

From your GitHub Enterprise instance, run the following cURL command to start an export job on Substitute your organization name and list of repositories to export.

curl -H "Authorization: token ${GITHUB_TOKEN}" -X POST \
  -H "Accept: application/vnd.github.wyandotte-preview+json" \
  -d'{"lock_repositories":false,"repositories":["githubschool/example-repository"]}' \

From the response body, we want to capture the migration url, denoted by the url key in the JSON. Save it to an environment variable.


Note: When running this command on your sandbox instance, set "lock_repositories" to false. When you do your production migration, set it to true, and it will prevent users from creating commits, pull requests, issues, etc on the repository on

The previous command will send a response immediately, indicating that the export of your repositories has begun on You’ll need to send a request to the migration status endpoint to monitor the status of the export. This command will poll the migration API every thirty seconds then output exported when it’s complete.

unset STATE
until [[ $STATE == *"exported"* ]]
  STATE="$(curl -s -H "Authorization: token ${GITHUB_TOKEN}" \
  -H "Accept: application/vnd.github.wyandotte-preview+json" \
  | grep -E '"state": ".*"')"
  echo $STATE
  sleep 5

When the job is complete, it will display "state": "exported" then exit.

Note: If you prefer to check the status of the export manually, and review more information about the export, you may simply send a simple cURL request to the migration API.

curl -s -H "Authorization: token ${GITHUB_TOKEN}" \
-H "Accept: application/vnd.github.wyandotte-preview+json" \

This next command will download the exported archive.

ARCHIVE_URL=`curl -H "Authorization: token ${GITHUB_TOKEN}" \
  -H "Accept: application/vnd.github.wyandotte-preview+json" \
  $MIGRATION_URL/archive`; \
  curl "${ARCHIVE_URL}" -o migration_archive.tar.gz

The archive is stored on GitHub’s servers, and will automatically be deleted after seven days. However, you can run this command to delete it immediately.

curl -H "Authorization: token ${GITHUB_TOKEN}" -X DELETE \
  -H "Accept: application/vnd.github.wyandotte-preview+json" \

Preparing to import

Next, you want to unpack the archive and prepare GitHub Enterprise for the import. In this step, GitHub Enterprise makes note of the objects that will be imported by saving references to them in a database table.

ghe-migrator prepare migration_archive.tar.gz

It’s important to capture the Migration GUID from the previous command’s output. Save that to an environment variable.

export MIGRATION_GUID=e9ebc5fe-9694-45af-925c-376651d933d7

It’s possible that users, repositories, organizations, or other entities will have conflicting names. ghe-migrator comes with a utility to detect and output these conflicts to a CSV file.

ghe-migrator conflicts -g $MIGRATION_GUID > conflicts.csv

conflicts.csv will contain the naming collisions for the import and their suggested actions to resolve those collisions. You may need to rename some models, map them from to their GitHub Enterprise counterpart, or merge them together, as in members of a team. You can read about how to resolve migration conflicts in our GitHub Enterprise documentation.

Once you’re satisfied with the mappings you’ve set in conflicts.csv, you can send that file back to ghe-migrator to be interpreted.

ghe-migrator map -i conflicts.csv -g $MIGRATION_GUID

This is also a good point to include any username mappings you may have set up earlier.

ghe-migrator map -i username_mappings.csv -g $MIGRATION_GUID

Import and audit

With mappings in place, you can now import our archive into GitHub Enterprise.

ghe-migrator import migration_archive.tar.gz -g $MIGRATION_GUID -u AdminUser

Where AdminUser is the username of a Site Admin on the GitHub Enterprise Appliance. After entering this command, you will be prompted to enter the GitHub Enterprise personal access token you set up during preparation.

Tip: To see what records are going to be imported or mapped before importing, you can run ghe-migrator audit -g $MIGRATION_GUID

After the import is complete, you can use ghe-migrator audit to see what was imported. Typically, you’ll want to filter for records that failed to import.

ghe-migrator audit -s failed_import,failed_map,failed_rename,failed_merge -g $MIGRATION_GUID

Once you are satisfied that the migration has completed successfully, you need to unlock the repositories on the GitHub Enterprise instance to allow users to access it. They are locked by default to prevent anyone from using them before you’re sure you’re happy with the import.

You may choose to unlock all repositories from this migration at once from the command line:

ghe-migrator unlock -g $MIGRATION_GUID -u YOUR-USERNAME -p YOUR-TOKEN

Or you may choose to unlock repositories individually using the Site Admin tools:

  1. Go to Admin Tools (stafftools) for each repository that was migrated.

    stafftools shortcut

  2. Click on Admin in the left sidebar.

    Admin link

  3. Click Unlock in the Single Repository Lock area.

    Unlock repo button


Now you’ll be able to use your repositories that were once on in your company’s instance of GitHub Enterprise. Important related information, such as issues and pull requests, will accompany your repositories. Should you require guidance with the ghe-migrator utility, GitHub Professional Services is here to help by offering on-site and remote migration assistance.

GitHub Enterprise 2.6 is here with faster, more approachable workflows

A new release of GitHub Enterprise is now available—and includes features requested by developers across the GitHub community. With GitHub Enterprise 2.6, we’re introducing tools and updates that will provide teams with even more options to create efficient, flexible, and friendly processes at every step of their development cycles.

All teams work differently, so it’s important that GitHub Enterprise supports the effort they put into creating efficient, effective tooling. In this release, administrators will find tools that save time throughout their development processes, including Issue templates and support for pre-receive hooks.

GitHub Enterprise 2.6 will also help teams have productive conversations. Developers can more efficiently review code and comments with new ways to view the history of their pull requests. And to make GitHub a better communication tool for all team members, we’ve added the option to drag and drop files into repositories using the GitHub interface and an editor to style issues and comments without markdown.

Ready to upgrade? Upgrade now.

Build a workflow that works for your team

The latest release adds features and support to help you and your team create even more tailored, efficient workflows. Administrators can now:

Protect branches with greater flexibility

With more than 100,000 people pushing to nearly 300,000 Protected Branches every week, we’ve found a few ways to make them better. Administrators now have more flexibility over their Protected Branches with the option to merge out-of-date pull requests and set restrictions on which users and teams can merge branches. Check out the documentation to learn how.

Let your team know what’s happening, fast

From GitHub Enterprise 2.6 onwards administrators can set up custom messages to share with developers on their GitHub Enterprise sign-in page. Administrators can also write custom messages for suspended users to appear when anyone with a suspended account tries to log in. See how you can use custom messages to communicate with your team.

Flexibly review pull requests

Effective code review catches bugs before they’re deployed, improves code consistency, and helps educate new developers. Since our last release, we’ve worked to make reviewing pull requests faster and more flexible. With GitHub Enterprise 2.6, you can:

  • Quickly find files to review, and filter them by name or extension
  • Filter changes by commit to see how a pull request has evolved through time
  • Pick up where you left off, and view new changes to pull requests since your last visit

Choose how you commit

Shape your workflow however you like. The organization of your Git history is just one of the choices to make, but up until now the merge button on GitHub only created merge commits. Now you also have the option to squash merge—squashing all of your commits into a tidy, easy-to-digest history. Learn more about squash merging.

Communicate better across GitHub, across teams

To help everyone on your team share their ideas, we’ve added features to streamline feedback and open up your development process to even more team members. Your team can now:

Upgrade today

GitHub Enterprise 2.6 is driven by developer and community feedback and includes some of our most requested improvements. Upgrade today, so your team can start taking advantage of them. You can also check out the release notes to see what else is new or enable update checks to automatically update your instance whenever there is a new release.

GitHub Enterprise 2.5 is now available

We are excited to announce the release of GitHub Enterprise 2.5. With this release, we’re introducing features and updates that will help development teams build software at scale with a focus on scalability, security, and management of GitHub Enterprise for development teams of any size.

It’s important that your GitHub Enterprise instance can support the way you work without skipping a beat, even if your team is 10,000 strong and growing exponentially. In this release, we’re introducing a better way to add new users to large installations, more ways to collaborate safely, and other tools and updates that will help support your team as it gets bigger.

You’ll also find a round of updates from a clean and simple design refresh to added support for Subversion, and more. Ready to upgrade? Download GitHub Enterprise 2.5.

A better way to grow

As your team grows, so does your GitHub Enterprise installation. For our customers with teams of tens of thousands of developers, the 2.5 release introduces clustering—a framework that helps administrators add more users to large installations.


Clustering was specifically designed for very large installations but requires some additional administrative resources. Check out the documentation to see how it works or contact your GitHub account manager to discuss scaling options.

A new way to cache intensive operations

For teams working on bigger software projects, large CI farms or similar collections of clients that perfom git fetch for large amounts of data at almost the same time can cause a substantial CPU and RAM load on our fileservers. With GitHub Enterprise 2.5, we have improved our resilience to the degraded performance that can happen with “thundering herds.”

More ways to protect your branches

GitHub Enterprise 2.4 included Protected Branches and Required Statuses to help teams collaborate safely: When you protect a branch, other developers can’t delete or force-push to it. You can also specify status checks that collaborators need to pass before merging a pull request.

With GitHub Enterprise 2.5, we are kicking off a preview period for the Protected Branches API—allowing instance administrators to help maintain a project’s conventions at scale and make sure no one loses any work.

Protected branches and required status checks are configurable per repository. To start using the API, check out the documentation.

Design updates

When you upgrade to GitHub Enterprise 2.5, parts of GitHub will look different. The repository and sign-in screens have updated designs that will make it easier to sign in and use GitHub from your browser.

A new look for repositories

The new repository design improves navigation, simplifies the page layout, and improves code performance under the hood. You can learn more about what’s changed from our recent blog post on the new design. In the meantime, here’s a summary:

  • The collapsing side menu is now a single, always present navigation, which improves accessibility and frees up more space for what matters to you—issues and pull requests.
  • The Code tab now more prominently emphasizes cloning and comes with a redesigned protocol switcher containing explicit menu items with explanatory text for each cloning method.

Simple sign-in and authentication screens

In addition to updating how repositories look, we have simplified the sign-in and authentication screens, so you can access your account more efficiently. The sign-up screen also includes a clearer sign-up link for new developers on your team who do not have a GitHub account, yet.

Enhanced Subversion support

For teams who use SVN commands to interact with their repositories, the latest version of GitHub Enterprise extends support for Subversion to versions 1.8 and 1.9. You can now use newer Subversion clients with GitHub, including features from 1.8 and 1.9.

Upgrade today

Check out the release notes to see what else is new or download GitHub Enterprise 2.5 now. You can also enable update checks to automatically update your instance whenever there is a new release.
