Push rules public beta

Say goodbye to unwanted files cluttering your repos, like *.jar or *.so. And limit who can make updates to sensitive files like your Actions workflows with the public beta of push rules. 🎉

A glimpse of push rules in action

You can now enable a new type of ruleset that allows you to control pushes to repositories based on file extensions, file path lengths, file and folder paths and file sizes. Push rules don’t require any branch targeting as they apply to every push to the repository, and also apply to all forks of the repo to ensure all pushes to the repository network are protected.

Push rules are now available for private and internal repositories for GitHub Teams, and across organizations for GitHub Enterprise Cloud.

Learn more about push rules in our documentation and join the community discussion to leave feedback.

Pull request merge queue is now generally available!

Today we are announcing the general availability of pull request merge queue! 🎉

Merge queue helps increase velocity in software delivery by automating pull request merges into your busiest branches. Screenshot of pull request merge queue

Before merge queue, developers would often need to update their pull request branches prior to merging to ensure their changes wouldn't break the main branch because of incompatibilities with pull requests already merged. Each of these updates caused a new round of continuous integration (CI) checks that would have to finish before the developer could attempt to merge. Merge queue automates this process by ensuring each pull request queued for merging is tested with any other pull requests queued ahead of it.

Merge queue is available on private and public repos on the GitHub Enterprise Cloud plan and all public repos owned by organizations.

Check out this video demo of how merge queue works.

Updates

Over the last few months, we've been busy fixing bugs and responding to feedback. As part of the general availability, we're announcing the following updates:

  • New: A merge_group webhook event with an action of destroyed is now published when a merge group is destroyed for any reason, including when it's merged or invalidated because a pull request is removed from the queue.
  • Fixed: The before and created properties of the push webhook event published when a temporary branch is created by the queue are now set to reflect a branch was created
  • Changed: Jumping to the front of the queue is now only available to admins by default in repos on GitHub Enterprise, but can be granted to individual users and teams using a custom repository role. Previously, any user with write access could jump the queue, but admins did not have a way to limit access to it or grant it to users without write access.
  • Fixed: A pull_request.dequeued webhook event is now consistently published whenever a pull request is removed from the queue for any reason, including when it has been merged by the queue.

A special thanks

A huge shout out and thank you to our customers in the community that participated in the public beta of this feature. Your input will help teams prevent traffic jams on their busiest branches! Hooray! ✨

Rebase commits now created using the merge-ort strategy

Last year, we made merging pull requests much faster by using the merge-ort strategy. Now, rebase commits get the same merge-ort treatment. This results in significantly improved speed: the P99 (the average time to complete rebases excluding the 1% slowest outliers) used to take around 3.6 seconds. P99 with the new strategy is 0.35 seconds. Because of the speedup, the fraction of PR rebases which fail due to timeouts dropped from 1.3% to 0.14%.

Fix to improve security around creation of pull requests in public repos

We've shipped a small fix to improve security around creation of pull requests in public repos.

Prior to this fix and under very specific conditions, a user could create a pull request in a public repo even though they did not have push access to either the base or head branch and were not a member of the repo's organization. Often these pull requests were created by mistake and quickly closed, but could still trigger unexpected GitHub Actions or other CI jobs.

This fix has no impact on the common open source workflow where a user forks a public repo, makes a change in their fork, and then proposes their change using a pull request. This fix also has no impact on pull requests already created.

We want to hear from you! Let us know if you have questions or feedback.

More secure private attachments

Previously, all attached (drag-and-dropped) images and videos on GitHub Issues, Pull Requests, Discussions, and wikis were available to view without authentication if you knew their direct URL. Now, future attachments associated with private repositories can only be viewed after logging in. This doesn’t apply retroactively to existing attachments, which are obfuscated by having a long, unguessable URL.

Email notifications sent from private repositories will no longer display images; each image is replaced by a link to view it on the web. Content inside a Git repository is not affected by this change and has always required authentication for private repositories.

Learn more about attaching files.

Pull request merge queue (public beta): API support and recent fixes

As we work towards general availability of pull request merge queue, we want to thank everyone that has provided feedback ❤ (keep it coming!) and let you know about some recent fixes and new API support.

See the public beta announcement to learn more about merge queue and how it can help increase velocity by automating pull request merges into your busiest branches.

🆕 API support

You can now interact with merge queue programmatically using new GraphQL APIs. Add or remove a pull request from the queue, see which pull requests are queued, get details about a queued pull request, and more. For example:

Call the enqueuePullRequest mutation to add a pull request to the queue or dequeuePullRequest to remove a pull request.

Use the mergeQueue field on Repository to list its contents or configuration. Use the mergeQueueEntry field on PullRequest to get details about a queued pull request including its state, position in the queue, estimated time to merge, and more.

🐛 Fixes

Some of the more noteworthy fixes made since the public beta launch:

  • Fixed: GitHub Actions workflows would not trigger on merge_group events in some repos
  • Fixed: failing queued pull request would remain failing even after checks were rerun and and passed
  • Fixed: confusing “pushed a commit that referenced this pull request” message would appear in the timeline
  • Fixed: commits could be pushed to queue-created prep branches (note: these commits were ignored and not merged, but it created confusion for some users)

Introducing Repository Rules Public Beta

Today we are announcing the public beta of repository rules! 🎉

Repository rules are GitHub’s next evolution of branch protections to help make your repositories more secure and compliant at scale.

Screenshot of ruleset overview

Rules allow you to easily define protections for branches and tags in your repositories and, if you are a GitHub Enterprise Cloud customer, to enforce them across your organization. It is also easier for everyone collaborating on your repositories to know what rules are in place.

Creating rules

Screenshot of creating a ruleset

At the core of rules is the ability to define rulesets. A ruleset is a collection of rules that are enforced together. For example, you could require that all commits to a branch are signed and that those commits have two reviewers. Rulesets can also be applied to tags, allowing you to enforce rules on releases.

The ruleset page is the central place to view and manage all the rules for a repository. It shows the rules that are currently in place and allows you to add new rulesets or edit existing ones.

When creating a ruleset, you define its enforcement status as active or disabled. Active rulesets must pass for a commit to be merged, while disabled rulesets are not enforced; they will not prevent merges but allow admins to craft rules before enforcing them. Enterprise Cloud customers can also evaluate rulesets: a “dry run” mode for understanding the impact of new rules before they are active and enforced.

It’s also easier to target branches and tags in rulesets, with options to select the default branch, all branches, and branches or tags that match an fnmatch pattern. You can add multiple patterns to a ruleset to apply it to different branch and tag naming styles.

Viewing the rules

You can always know what rules are in place for a repository.

Anyone with read access to a repository can view its rules and what they mean. The rulesets overview is linked from the branches page by clicking the shield icon, and from a pull request, and from the output of the Git CLI when rules block a push.

From here, you can filter rules by branches or tags to understand how a rule might be enforced on your next push.

Screenshot of read only view of rules

Getting Started

Repository rules are now available to all GitHub cloud customers. To get started, visit the documentation to learn how to enable and use rules. For Enterprise Cloud customers, visit the documentation to learn about organization rulesets and more.

We want to hear from you on how we can improve repository rules! Join the conversation in the repository rules public beta discussion.

Introducing the GitHub Markdown Helpers Public Beta

GitHub users write a lot of Markdown; so much so that we render 2 billion Markdown files everyday; at peak times, we're processing 1,300 Markdown files a second! Any opportunity we have to shave a few seconds off of the Markdown authoring experience on GitHub is time well-spent.

Introducing Markdown Helpers powered by Slash Commands

To use Markdown Helpers, simply type / on Issues, Pull Requests, or Discussion descriptions/comments and use the subsequent dialog to choose from a number of useful Markdown shortcuts.

Use shortcuts like /table to make Markdown tables a breeze, or /details to make selectively showing content to readers much easier than remembering the HTML formatting.

As part of our first release, we've included 6 out-of-the-box features which we hope will help teams author Markdown faster and with less context switching:

  • Code Block
    • Support for language-specific syntax highlighting
  • Details
    • Specify details that the reader can open and close on demand
  • Saved Replies
  • Table
    • Easily insert Markdown Tables
  • Templates
    • Easily populate your Repository's Issue or Pull Request templates directly from Slash Commands!
  • Tasklist
    • Easily insert a Tasklist
    • Note: Tasklists are currently in Private Beta, only users in organizations added to the Private Beta will see this option)

We'd love to hear from you!

Be sure to check out the official Slash Commands documentation for more details on the commands we're releasing today.

Anything we missed? Got an idea for a great Slash Commands feature?

Please leave us some feedback in our Feedback Discussion about how you'd like to use Slash Commands on GitHub.

Comment on files in a pull request (public beta)

Commenting directly on a file in a pull request (not just a specific line) is now available in public beta! 🎉

With this capability you can now comment on deleted, binary (including images), and renamed files in a pull request. You can also comment generally about a changed code file without having to attach the comment to a specific line.

How it works

To comment on any file in a pull request, click the Comment on this file button in the header of the file (next to the Viewed checkbox):
image

Comments on files appear in the Files Changed and Conversation tabs and can be replied to and resolved like regular review comments.

Feature Preview: Rich Jupyter Notebook Diffs

Rich diffs of Jupyter Notebook files in pull requests are now available in preview. With the feature preview enabled, you can compare cell-level inputs and outputs (including images), as well as notebook and cell metadata, thanks to nbdime. Check it out:

image

The rich diff functionality will need to be enabled via the Feature Preview menu found when clicking on your avatar. Click here to learn more about feature previews and how to enable it. Please note that this is an early-access feature and there are some limitations; most notably, you cannot currently comment on lines in rich diff mode and will need to toggle the source diff to do so.

We'd love to hear from you! Once you try it out, let us know what you think in this feedback discussion. Stay tuned for future updates!

Note: If you were previously enrolled in the private beta for this feature and no longer see rich diffs, you may have to re-enable the feature preview via the menu.

Manage branch protection rules with a new permission

You can now create a custom role to manage branch protections without having to grant the Admin role. Previously, to manage branch protections you had to be an Admin which provides additional permissions that may not be needed. For tighter control of Admin permissions, you can now craft a custom role that has the Edit repository rules permission, allowing just the right amount of access.

Image of Custom roles that shows the new Edit Repository Rules permission

This permission grants the ability to create, edit, and delete both branch protection rules and protected tags.

For more information, visit Managing custom repository roles for an organization in the GitHub documentation.

We appreciate feedback on this in GitHub's public feedback discussions.

Pull request merge queue (public beta)

Today we are announcing the public beta of pull request merge queue for repos on GitHub Enterprise Cloud and open source organizations! 🎉

Merge queue helps increase velocity in software delivery by automating pull request merges into your busiest branches.

Pull request merge queue

Before merge queue, developers were often required to update their pull request branches prior to merging to ensure their changes wouldn't break the main branch when merged. Each update resulted in a fresh round of continuous integration (CI) checks that would have to finish before the developer could attempt to merge. If another pull request got merged, every developer would have to go through the process again.

Merge queue automates this process by ensuring each pull request queued for merging is built with the pull requests ahead of it in the queue.

Queueing a pull request to merge

If your pull request targets a branch that uses merge queue, instead of merging your pull request directly when it meets the requirements to merge, you will add it to the queue by clicking Merge when ready from the pull request page or from GitHub Mobile.

Queue to merge

The queue then creates a temporary branch that contains the latest changes from the base branch, the changes from other pull requests already in the queue, and the changes from your pull request. CI then starts, with the expectation that all required status checks must pass before the branch (and the pull requests it represents) are merged.

If a queued pull request has merge conflicts or fails any required status check, it is automatically removed from the queue when it reaches the front, and a notification is sent. Once the problem is resolved, it can be added back to the queue.

Learn more about merging a pull request with merge queue from the pull request page. You can also queue your pull request on the go using the beta version of GitHub Mobile from iOS TestFlight or Google Play (Beta)!

Viewing the queue

Always know where you are in the queue.

The queue details page, which can be accessed from the Branches page or pull request page, shows the pull requests in the queue and status for each, including the required status checks and estimated time to merge. It also shows how many pull requests have been merged and the trend over the last 30 days.

Merge queue details page

Depending on your permissions, you can also remove a pull request from the queue or clear the queue from this page.

Getting started

Merge queue can help improve overall velocity and avoid manual branch updates that impact developer productivity. Learn more about how to enable merge queue on your busiest branches.

We want to hear from you on how we can improve merge queue! Join the conversation in the merge queue public beta discussion.

New Branch Protections: Last Pusher and Locked Branch

Today we're releasing two new branch protections.

Require approval from someone other than the last pusher

Now, before a pull request can be merged, you can require it to be approved by someone other than the last pusher.
Meaning, the most recent user to push their changes will need a pull request approval regardless of the Require approvals branch protection. Or in the case of 1 approval required, someone other than the last user to push their changes will also need to approve. If the approvals come from other folks than the last pusher, those two approvals will be sufficient.

Screenshot of Last Push protection enabled.

Lock branch

This allows for branches to be locked, prohibiting changes. You can lock a branch allowing you to have a maintenance window and prevent changes, or to protect a fork so it only receives changes from its upstream repository.

To use this feature in a branch protection rule, enable Lock branch.

Screenshot of Lock branch with fork sync enabled

For more information, read About protected branches in the GitHub documentation.

We appreciate feedback on this and other topics in GitHub's public feedback discussions.

Reverted recent change that caused some pull requests to be incorrectly marked as merged

On September 5, 2022, we reverted a recent change to our indirect pull request merge logic that was causing some pull requests to be incorrectly marked as merged. This could happen if a pull request's head branch was force pushed and resulted in the pull request showing no new commits compared to the base branch. The original change went live on August 1, 2022 and caused confusion about why some pull requests were marked as merged by a contributor who did not have the necessary permissions. It also had the side effect of removing the "first time contributor" flag from these contributors without them having made an accepted contribution by the repository maintainers. Depending on repository settings, this could have allowed first time contributors to run GitHub Actions workflows based on their branches.

At no point were users able to push changes or merge pull requests in repositories to which they did not have appropriate authorization. After the change was reverted, GitHub conducted an investigation into any bypasses of the "first time contributor" flag and found no evidence of abuse.

Git commit author shown when squash merging a pull request

The author of the Git commit created when squash merging a pull request is now shown before merging. Previously, the commit author was only shown when merging with a merge commit.

image

Also, if the user merging the pull request also opened it and has multiple email addresses configured, a drop-down now lets them choose a different email address to use for the commit's author.

image

These improvements are designed to ensure Git commits created by squash merging are associated with the correct email address.
