Git Large File Storage v1.0

After months of letting our early adopters kick the tires, Git Large File Storage (Git LFS) has reached a 1.0 milestone and is now available to all repositories on

Git LFS is an open source Git extension that we released in April for integrating large binary files into your Git workflow. Distributed version control systems like Git have enabled new and powerful workflows, but they haven’t always been practical for versioning large files. Git LFS solves this problem by replacing large files with text pointers inside Git, while storing the file contents on a remote server like

We’re hugely appreciative of the community that’s sprung up around Git LFS. This milestone contains features and fixes that came directly from your feedback and pull requests. Some notable changes include:

  • A fully rewritten HTTP client and API specification that improves concurrency and reduces overhead when transferring thousands of files
  • New git lfs fetch and git lfs pull commands that download objects much faster than the standard Git smudge filter
  • Options for customizing what files are automatically downloaded on checkout
    • Selectively ignore a directory of large files that you don’t need for daily work
    • Download recent files from other branches
  • Improvements to git lfs push that filter the number of commits to scan for eligible LFS objects to upload. This greatly reduces the time to push new feature branches
  • A Windows installer and Linux packages for more convenient installation
  • An experimental extension system for teams that want to customize how objects are stored on the server

Git LFS is now available to all users on, just install the client to get started.

GitHub supports Universal 2nd Factor authentication

To help users better secure their accounts, we are expanding GitHub's authentication system to support FIDO Universal 2nd Factor (U2F)—a rapidly growing open authentication standard.

GitHub encourages developers to build U2F support into their own applications as well, enabling authentication with simple user experience and strong security using public key cryptography. U2F is built to protect against phishing and man-in-the-middle attacks, allowing one U2F authenticator to access any number of services without any shared secrets. Since U2F has native support in platforms and browsers, there’s no need for drivers or client software. Read more about how U2F keys work or take a look at the GitHub U2F documentation to learn how to associate a U2F key with your GitHub account.

In order to take advantage of the security improvements provided by U2F, you'll need to purchase a hardware key. You can purchase the U2F key of your choice from a range of vendors. We are partnering with Yubico, inventor of the YubiKey, co-creator of the U2F protocol, and a leading provider of U2F authenticators. Together with Yubico we are offering discounts to GitHub users for a limited time through a special offer page where you will verify your GitHub account and place your order:

  • While supplies last, GitHub users can purchase special edition U2F Security Keys for $5 plus shipping and handling (regular price $18; 5,000 special edition keys available).
  • After the special keys are gone, all GitHub users are eligible for a 20% discount on U2F-certified YubiKeys, for a limited time.
  • In addition, all students who are eligible for the Student Developer Pack will receive a 20% discount on any U2F-certified YubiKey.

We hope you'll take this step to keep your information secure.


New organization permissions now available

We've begun rolling out major improvements to GitHub organization permissions to all organizations on These improvements include new customizable member privileges, fine-grained team permissions, and more open communication. Over the next few days, all organization owners will be able to take advantage of the new system.

Announced a few short months ago, these improvements give your organization the flexibility to work the way you want. To recap, here are just a few highlights:

  • (Opt-in) Members can view and mention all teams, even when they're not on those teams.
  • (Opt-in) Members can create repositories without help from an owner.
  • Members can create new teams to self-organize with the people they work with.
  • Owners can give just the right amount of access to contractors and interns by adding them to repositories without giving them the privileges of organization members.
  • And many more! Learn about GitHub's improved organization permissions.

Coding together just got easier.

Tickets are still available, we'll see you in a couple weeks.

Easier feeds for GitHub Pages

If you publish a blog using GitHub pages, it's now easier for others to subscribe to updates. The Jekyll Feed plugin, now available to all GitHub Pages sites, can automatically generate an Atom (RSS-like) feed of your most recent posts.

While it's always been possible to generate feeds using hand-written XML, the Jekyll Feed plugin includes a battle-tested template that handles things like encoding issues and relative URLs, allowing you to concentrate on what matters: your content.

For more information, including installation instructions, see the Feeds for GitHub Pages help article.

Happy syndicating!

Protected branches and required status checks

It’s all too easy to force push to the wrong branch, overwriting someone else’s changes with your own. Sometimes it results in losing work (unless you know how to undo almost anything in Git).

Over the next few weeks we’ll be rolling out a new feature called Protected Branches which gives repository administrators the ability to disable force pushes to specific branches. When it’s enabled for your repositories you’ll be able to go to the Branches tab in repository settings and protect branches:

Repository Branches settings page

In addition to blocking force pushes, a protected branch can have required status checks. Required status checks make integrations that use our Status API enforceable and you can disable the merge button until they pass:

Pull Request merge area with required status checks

When using required status checks, your branch must be up-to-date to ensure your tests will pass after merging. The new “Update branch” button lets you merge the latest changes from the base branch of the Pull Request with one click.

GitHub Desktop is now available

The new GitHub Desktop is now available. It's a fast, easy way to contribute to projects from OS X and Windows. Whether you're new to GitHub or a seasoned user, GitHub Desktop is designed to simplify essential steps in your GitHub workflow and replace GitHub for Mac and Windows with a unified experience across both platforms.


Branch off

Branches are essential to proposing changes and reviewing code on GitHub, and they’re always available in GitHub Desktop’s repository view. Just select the current branch to switch branches or create a new one.


Craft the perfect commit by selecting the files—or even the specific lines—that make up a change directly from a diff. You can commit your changes or open a pull request without leaving GitHub Desktop or using the command line.

Merge and Deploy

Browse commits on local and remote branches to quickly and clearly see what changes still need to be merged. You can also merge your code to the master branch for deployment right from the app.


Ready to start collaborating? Download GitHub Desktop. If you're using GitHub for Mac or Windows, the upgrade is automatic.

Improving map data on GitHub

You've been able to view and diff geospatial data on GitHub for a while, but now, in addition to being able to collaborate on the GeoJSON files you upload to GitHub, you can more easily contribute to the underlying, shared basemap, that provides your data with context.

The basemap we use — the layer that includes common elements like roads, rivers, and buildings over which your data is displayed — is powered by OpenStreetMap. You can think of OpenStreetMap somewhat like Wikipedia for geospatial data. It's a community of mappers and an open, collaborative dataset.

Next time you view a GeoJSON file on GitHub, if you spot something that looks a bit off, simply click the "improve the underlying map" link in the top right corner of the map. From there, you can edit the map in your browser with a few clicks, or if you're in a hurry, you can leave a note for an editor to review later.

example of clicking improve this map link

Last year millions of people used GitHub to collaborate on geospatial data. By making it a little easier to contribute back, we hope that the GitHub community can support the OpenStreetMap community, without which none of this would be possible.

Happy social mapping!

Announcing Git Large File Storage (LFS)

Distributed version control systems like Git have enabled new and powerful workflows, but they haven't always been practical for versioning large files. We're excited to announce Git Large File Storage (LFS) as an improved way to integrate large binary files such as audio samples, datasets, graphics, and videos into your Git workflow.

Git LFS is a new, open source extension that replaces large files with text pointers inside Git, while storing the file contents on a remote server like or GitHub Enterprise.


Git LFS is easy to download and configure, works on all major platforms, and is open sourced under the MIT license.

Early access to Git LFS support on

We're ready to roll out Git LFS support to a select group of users. If you'd like to be one of the first to try it out on, sign up for early access using your GitHub account.

In the future, every repository on will support Git LFS by default.


Every user and organization on with Git LFS enabled will begin with 1 GB of free file storage and a monthly bandwidth quota of 1 GB. If your workflow requires higher quotas, you can easily purchase more storage and bandwidth for your account.
