Improved pull request merge experience now in public preview

To help you better understand the state of your pull request and get it merged faster, the merge experience on the pull request page has been improved! This experience is currently in public preview.

Screen shot of the updated merge box page on the pull request page showing that 1 review is required, a list of status checks (some failing), and a message about not having any merge conflicts.

What’s new

We’ve maintained the familiar look of the existing merge experience while incorporating several usability improvements:

  • Checks grouped by status: checks are now grouped by status with failing checks prioritized at the top of the list, making it easier to identify issues that need attention
  • Checks ordered alphabetically: status checks are now ordered alphabetically to make it easier to find a specific check
  • Commit metadata validation: errors from failing commit metadata rules (like non-compliant commit messages) can now be corrected and retried
  • Improved accessibility: consistent keyboard navigation, focus management, and landmarks help make the experience more accessible to everyone

For a more complete list of changes visit the feedback discussion.

Custom models for GitHub Copilot are now in Limited Public Beta

Custom models for GitHub Copilot are now available in Limited Public Beta for Copilot Enterprise. This new capability lets you fine-tune Copilot to better understand and align with your organization’s unique coding practices, improving the relevance and accuracy of code suggestions across your projects.

What are custom models?

Custom models are large language models (LLMs) that have been fine-tuned using your organization’s codebases. By training a model on your proprietary libraries, specialized languages, and internal coding patterns, Copilot delivers code suggestions that are more context-aware and tailored to your organization’s needs.

During this beta, you can create a custom model using your GitHub repositories. Optionally, you may also enable the collection of code snippets and telemetry from developers’ Copilot prompts and responses to further fine-tune the model. This process closely aligns Copilot’s suggestions with your coding practices, making them more relevant and accurate. As a result, your development teams will spend less time on code reviews, debugging, and manual code adjustments, ultimately boosting team productivity and ensuring more consistent code quality.

Custom-Model-Training-Config

Importantly, your data remains entirely yours. It is never used to train another customer’s model, and your custom model is kept private, ensuring full control, security, and privacy.

When to Use Custom Models

Custom models enable you to make Copilot’s suggestions more relevant to your specific needs, which can lead to higher acceptance rates of the code suggested by Copilot among your developers. Consider using custom models in the following scenarios:

  • Enhance Library and API Usage: When your organization relies heavily on custom libraries or APIs that aren’t well-represented in public datasets, a custom model can prioritize these in its suggestions, making it easier for your developers to follow internal standards.

  • Improve Support for Specialized Languages: If your team works with less common or proprietary languages, custom models can make Copilot much more effective. Fine-tuning helps Copilot understand these languages better, reducing friction and improving productivity.

  • Adapt to Evolving Codebases: As your codebase changes, you have full control over when and how often to retrain your custom model. By regularly retraining, you can ensure that Copilot keeps up with the latest coding patterns, so it continues to provide relevant and accurate suggestions.

How to Get Started

  1. Sign Up for the Beta:
    Sign up here to participate in the Limited Public Beta and make sure your organization is on the Copilot Enterprise plan.

  2. Prepare Your Repositories:
    Choose the repositories that best reflect your organization’s coding standards. Include those with proprietary libraries, specialized languages, or key internal frameworks to get the most out of fine-tuning. If your enterprise has multiple GitHub organizations, note that only one organization and its repositories can be used for training during this beta.

  3. Enable Telemetry Collection:
    To further customize your model, consider enabling the collection of code snippets and telemetry related to developers’ prompts and Copilot’s suggestions. This data will be securely collected and used for additional fine-tuning, improving the accuracy and relevance of Copilot’s output for your team. Your data will only be used to enhance your custom model and will not be shared with others. For more details about our data-handling practices, please visit the Trust & Security Center or review GitHub’s data protection agreement.

  4. Training and Usage:
    After setup, your custom model will be trained using the selected repositories. Once it’s ready, your developers’ IDEs will automatically start using the custom model, which will inform all in-line code completions.

  5. Monitoring & Quality Assessment:
    Regularly retrain your custom model to keep it aligned with new code and evolving practices. Use the Copilot Usage Metrics API to track metrics like suggestion acceptance rates and see how much it’s improving.

Actions Usage Metrics public beta

Customers desire clear, relevant, and actionable insights about how Actions workflows are being used in their organization. Today, we are thrilled to announce that Actions Usage Metrics is available in public beta for GitHub Enterprise Cloud plans.

Actions Usage Metrics screenshot

Time is the most important metric for DevOps and DevEx teams. The question they want answered is, “where are all my minutes going?” Actions Usage Metrics addresses this question and others by focusing on minutes used per workflow, job, repository, runtime OS, and runner type. This data helps organizations locate areas of improvement in their software delivery lifecycle, saving time and money.

Customers can filter data by any combination of workflows, jobs, repositories, runtime OS, and runner type to view total minutes, number of jobs, workflow executions, and more. All usage metrics, filtered or not, can be downloaded as a .csv file to use with your tool of choice.

By default, organization owners can access Actions Usage Metrics. However, access permissions can be granted to other members or teams using Actions fine-grained permissions. This ensures the right level of access to Actions Usage Metrics data, enabling informed decisions and improvements.

To learn more about Actions Usage Metrics, check out our docs or head to our community discussion.

Repository Rules – configure merge queue rule – public beta

Configuring merge queue in your repo rulesets is now available in public beta!

Screenshot showing the configuration of merge queue inside a ruleset

Merge queue & rule insights

Until now, rule insights would only list one pull request as merged even when multiple pull requests were merged by the queue at the same time. Also in this beta, each pull request in a merge queue will have an individual record in rule insights, linked to the actor that added the pull request to the merge queue.

Example screenshot showing rules insights and all PRs from a queue

Within the additional data of a rule insight dialog you can now see all the pull requests that merged in the same group along with the checks needed for the queue.

Example screenshot of details of a queue in rule insights

Limitations

  • The merge queue rule cannot be configured via an API. This feature will be available in the near future.
  • Merge Queue for branch protections and repository rules do not support wildcard patterns
  • Not supported in organization rulesets.
  • Multiple merge queues configured against a single branch will prevent merging.

Dependabot Grouped Security Updates Public Beta

Reduce pull request noise and fix multiple security alerts at once with Dependabot grouped security updates.

Starting today, you can enable grouped security updates for Dependabot at the repository or organization-level. When you click “Enable” for this feature, Dependabot will collect all available security updates in a repository and attempt to open one pull request with all of them, per ecosystem, across directories. There is no further configuration available at this time.

Known limitations

  • Dependabot will NOT group across ecosystem (e.g. it will not group pip updates and npm updates together)
  • Dependabot WILL group across directories (e.g. if you have multiple package.json’s in different directories in the same repository)
  • If you have version updates enabled as well, Dependabot will NOT group security updates with version updates
  • If you use grouping for version updates, your groups configuration in dependabot.yml will NOT apply to security updates

To enable this feature, go to your repository or organization settings page, then go to the Code security and analysis tab, and click “Enable” for grouped security updates (this also requires each affected repository to enable Dependency graph, Dependabot alerts, and Dependabot security updates). When you enable this feature, Dependabot will immediately attempt to create grouped security pull requests for any available security updates in your repository.

We’d love to hear your feedback as you try this feature! Join the discussion within GitHub Community.
