Build Copilot Extensions faster with skillsets

Skillset header image

Today we’re introducing skillsets, a new lightweight way to build GitHub App-based Copilot Extensions alongside our existing agents approach. While agents offer full control over the user interaction, skillsets make it easy to integrate external tools and services into Copilot Chat by defining simple API endpoints – no AI expertise needed!

What’s new ✨

  • Let Copilot handle all AI interactions and response formatting
  • Define up to 5 skill endpoints that Copilot can call
  • Simple JSON schema configuration
  • Quick setup with minimal code

Benefits for builders ⚡️

  • Faster Development: Focus on your core functionality instead of AI interactions
  • Simple Implementation: Just define API endpoints, without managing LLM logic
  • Minimal Setup: No complex server infrastructure required, with the option to use existing APIs
  • Consistent Experience: Copilot maintains natural chat interactions automatically

Choosing your integration path 🛠

  1. Skillsets: Perfect for straightforward integrations like data retrieval and basic actions. You provide the API endpoints, and Copilot handles workloads like prompt crafting and response generation.
  2. Agents: Ideal for complex workflows needing custom logic, flexible prompt crafting, or specific LLM models. You control the entire interaction.

How it works 🏗️

End users interact with skillset-based extensions just like any other Copilot Extension. Just type @ followed by the extension name and ask in natural language. Behind the scenes, Copilot:

  • Analyzes the query to determine which skill to call
  • Structures the API request based on your JSON schema
  • Calls your endpoint to get the data
  • Formats and generates the response in chat

Architecture

architecture diagram

Requirements for extension builders

  • Access to GitHub Copilot
  • For organizational builds: Free, Team, or supported Enterprise Cloud organization types
  • Skillsets only apply to extensions built as GitHub Apps, and not VS Code chat participants

Getting started 🚀

Check out our documentation to learn how to build your first skillset.

Already built a Copilot Extension as an agent? Existing agent extensions can be converted into skillsets, but one extension cannot be both a skillset and an agent.

Persistent commit signature verification now in public preview

We’re excited to introduce persistent commit signature verification, a powerful new feature designed to elevate the security and reliability of your repository’s commit history.

Starting today, GitHub verifies commit signatures when they are first pushed, and once a commit’s signature is verified, it remains verified within its repository’s network. This supports organizations in maintaining a secure and accurate record of contributions without constantly rechecking the validity of every signature. You can view these persistent verifications directly on GitHub, where a quick hover over the Verified badge displays the timestamp of the original verification.

Efficient, Secure, and Transparent Verification

Previously, commit signatures were verified on demand, via a process that was not performant and had risks of previously verified signatures becoming “unverified” due to various reasons like service outages or key rotations.

Persistent commit signature verification solves these issues by validating signatures at the time of the commit and storing the verification details permanently. This also brings consistency to the commit history as git commits are immutable and they do not natively support key rotation.

Managing commit signatures can be a challenge, but persistent records ensures that verified commits remain verified over time, even if signing keys are rotated, revoked, or contributors leave the organization.

How to tell if the verification has a persistent record?

When a commit’s signature is verified upon being pushed to GitHub, the verification record is stored alongside the commit. This record is immutable, ensuring that the verified status is maintained permanently.

You can view the verification timestamp by hovering over the Verified badge on GitHub or via the GitHub REST API which now includes a verified_at field.

Learn more about commit signature verification on GitHub.

Designed for Real-World Key Rotation and Contributor Management

For organizations managing signature verification – whether GPG, SSH, or X.509 keys using S/MIME – persistent commit signature verification provides a robust way to ensure signature integrity across the board. Now, any commit with a verified status can retain that status, even when the signing key is rotated or removed.

Persistent commit signature verification is applied to new commits only. For commits pushed prior to this update, persistent records will be created upon the next verification, which happens when viewing a signed commit on GitHub anywhere the verified badge is displayed, or retrieving a signed commit via the REST API. This ensures that your repository remains secure while providing flexibility in managing your verification practices.

This approach lays the groundwork for future improvements aimed at enhancing repository integrity and authenticity of contributions within GitHub.

Key Management Caveat: Revocation and Expiration

Persistent commit signature verification ensures that verified commits retain their status indefinitely, it’s important to note this records the state of the signature at the time of the commit. If a signing key is later revoked, expired, or otherwise changed, GitHub will not re-verify previously signed commits or retroactively modify the verification status.

For organizations using S/MIME keys, this does introduce a minor change: revoked S/MIME keys will not verify new commits or those without an existing persistent record. Since git commits are immutable, persistent commit signature verification aligns with this concept by maintaining the original verification status without change. Organizations may need to manage key states directly to align with their security policies, especially in cases involving frequent key rotation or revocation.

This approach ensures that once a commit is verified, it remains trusted based on the record at the time, bringing consistency and long-term reliability to your commit history.

Moving Towards a Future with Secure and Authentic Contributions

With this launch, we’re addressing a key issue: commit verification that isn’t fragile or temporary. Teams can now implement signing key policies, without worrying about losing the verified status of past work.

Stay tuned for more updates as we continue to enhance commit verification. If you have feedback or suggestions, please let us know through our GitHub Discussions forum.

The GitHub Enterprise Server 3.15 Release Candidate is available

The GitHub Enterprise Server 3.15 release candidate is here

You can now download the GitHub Enterprise Server 3.15 release candidate to try out the new features in this latest version. Version 3.15 gives customers enhanced deployment requirements and security controls. Here are a few more highlights in the 3.15 release:

  • We have updated root disk size requirements. New installations of GitHub Enterprise Server version 3.15 and upgrades to 3.15 now require a root disk size of at least 400GB. System will not boot otherwise. For more information on how to increase the root disk size in the appliance, see increasing storage capacity.

  • We have also updated minimum server specs recommended to run GHES. For more information, see minimum recommended requirements.

  • You can now interact with project status updates using GraphQL and webhooks. This unlocks new ways to automate how you provide and gather project status update information. For more information, see GitHub Projects.

  • Custom properties now support new property types: multi select and true/false. Organization repositories can now be queried and filtered via properties. Both the UI and API are supported. Read about filtering repositories.

  • Code security configurations are now available in GHES. These configurations simplify the rollout of GitHub security products at scale. They help you define collections of security settings and apply them across groups of repositories. We have retired the old organization-level code security settings UI experience along with the API parameters that complemented it. For more information, see code security configurations.

  • Secret scanning push protection is now supported for content upload REST API endpoints – create a blob and create or update file contents. Push protection blocks you from pushing secrets to a repository and generates a secret scanning alert whenever you bypass the block.

  • CodeQL‘s support for Swift and Kotlin is now generally available. CodeQL is the static analysis engine that powers GitHub code scanning.

  • Organization owners can now grant a user or team access to all of the repositories in their org with a single click. New pre-defined roles have been added to the organization settings, under Organization Roles > Role Management, where all organization owners can view and assign them. These can be further customized as well to grant specific repository permissions across your organization. For more information, see organization roles.

Release Candidates are a way for you to try the latest features early, and they help us gather feedback to ensure the release works in your environment. They should be tested on non-production environments. Read more about the release candidate process.

To learn more about GHES 3.15, check out release notes, or download the 3.15 release candidate now.

Copilot content exclusion is now generally available in IDEs

We’re excited to announce that content exclusion for Copilot is now generally available for all Copilot Business and Copilot Enterprise users! This feature, previously available only in beta, allows you to control which code Copilot can access to generate suggestions. When you exclude content from Copilot:

  • Code completion will not be available in the affected files.
  • The content in affected files will not inform code completion suggestions in other files.
  • The content in affected files will not inform GitHub Copilot Chat’s responses.

How to exclude content using content exclusions for Copilot?

Enterprise, organization, and repository admins can set up exclusions through their settings, as outlined in our documentation: Excluding content from GitHub Copilot

For availability across surfaces, please check the information here: Availability of content exclusion

Enterprise admin Copilot Content Exclusions

For users previously in beta:

Previously Used Enterprise-Level Rules:

  • If you already had enterprise-level exclusion rules set up (as described in previous changelog), you won’t experience any changes. These rules will continue to function as intended.

Previously Used Organization-Level Rules:

  • If your exclusions were previously set at the organization level but not the enterprise level: Org-level rules will no longer apply enterprise-wide. They will be limited to users who are assigned Copilot seats from your org, regardless of whether enterprise-level rules are applied.

Upcoming changes to data retention for Events API, Atom feed, /timeline and /dashboard-feed features

Currently, you are able to query back up to 90 days worth of events from data tables you have access to when reviewing or utilizing specific events features: Events API (including push events), Atom feed, /timeline, or /dashboard-feed. On January 30th, 2025, we will be modifying the window of data retention for these features from 90 days to 30 days.

Why are we making changes?

We are making this change to help GitHub continue to scale for all our users, while continuing to provide existing customers of these features with the ability to still query and view recent important event information.

Which APIs will be impacted in this change?

The relevant APIs that will be affected are:
– /events : List public events
– /networks/{owner}/{repo}/events : List public events for a network of repositories
– /orgs/{org}/events : List public organization events
– /repos/{owner}/{repo}/events : List repository events
– /users/{username}/events : List events for the authenticated user
– /users/{username}/events/orgs/{org} : List organization events for the authenticated user
– /users/{username}/events/public : List public events for a user
– /users/{username}/received_events : List events received by the authenticated user
– /users/{username}/received_events/public : List public events received by a user
– /feeds : Get feeds

When can you expect the changes to occur?

On January 30th, 2025, we will be reducing the window that can be queried across those specified events features from 90 days to 30 days. In advance of that, we will test this change for 24 hours on December 3rd, 2024.

Additional support

As part of this change, we are adding an additional event (DiscussionEvent) as a new EventType for the Events API. This will allow you to query for an event related to Discussions that was not previously available.

We recommend leveraging a workflow that uses weekly or daily exports if you require further historical access.

Where can I learn more?

If you have concerns, comments, or feedback, please join us in this Discussion in the GitHub Community.

Updated limits for GitHub App private keys and scoped tokens

GitHub Apps are now subject to a limit of 25 private keys per application and can create scoped tokens with access to more repositories. These changes support safer key management and access practices in your applications.

25 key limit for GitHub Apps

There is now a limit (25) on the number of private keys a GitHub App can have registered at one time. 99.99%+ of apps are below this limit – the ones above this limit will be unable to create more keys until they have deleted all but 24 of their keys.

Use of multiple keys for zero-downtime key rotation is encouraged. However, sharing keys among multiple parties is not recommended, which an unlimited number of keys lead developers towards. This new limit should help app developers look for safe alternatives earlier in the development lifecycle.

See our documentation on GitHub App key management for more details and best practices.

No limit on repositories for permissions-scoped tokens

In February 2024, GitHub placed a limit on the complexity of the scoped tokens that apps could request. Now, part of this limit no longer applies. Apps can now be installed on any number of repositories in an organization and request a scoped token for all those repositories. The limitation on tokens that request a subset of both permissions and tokens remains.

To learn about scoped tokens, and how they can improve the least-privilege access of your App’s tokens, see our GitHub App authentication documentation.

Organizations can now enable 2FA requirement without removing non-compliant members [GA]

Enterprises can now broadly roll out two-factor authentication (2FA) to all members of their organization through an enhanced 2FA enrollment experience in GitHub. With this update, non-compliant users will no longer be removed from organizations when an organization begins enforcing 2FA.

2FA will be enforced via conditional access policies, which means members who have not yet enabled 2FA will continue to have their organization membership, but be blocked from visiting any organization resources until they enable 2FA.

This enables organizations to enable a broader 2FA enrollment without disrupting the membership status of their members who are yet to enable 2FA. This also enables members without elevated privileges to enable or disable 2FA on their accounts without losing organization membership.

Learn more about how GitHub is securing developer accounts using 2FA, and why we’re urging more organizations to join us in these efforts.

EMU OIDC CAP support is now enhanced to protect web sessions [Public Preview]

If you are using GitHub Enterprise Cloud with EMU and using OpenID Connect (OIDC) SSO, this new feature, currently in public preview, will help enforce IdP-defined IP restrictions to protect all web interactions on GitHub.

Currently, when your enterprise uses OIDC-based SSO and if any of the enterprise members change their IP address, GitHub can validate their access to your enterprise and its resources using your IdP’s Conditional Access Policy (CAP). IdP CAP validations previously covered only non-interactive flows where users authenticate with a personal access token or SSH key.

With this launch, we are now extending these validations to include all interactive web flows. If you already had IdP CAP turned ON previously, you will need to explicitly opt-in into extended protection for web sessions from their enterprise’s “Authentication security” settings. If you enable IdP CAP support after today’s public preview launch, you will still need to opt in to get the coverage across web flows.

When this feature is generally available, we plan to have both interactive and non-interactive flows protected by the IdP CAP validations for all customers by default and remove the additional step of requiring to opt-in.

Learn more about GitHub’s support for your IdP’s Conditional Access Policy.

Notice of breaking changes for GitHub Actions

Ubuntu-latest upcoming breaking changes

We will migrate the ubuntu-latest label to ubuntu 24 starting on December 5, 2024 and ending on January 17, 2025. The ubuntu 24 image has a different set of tools and packages than ubuntu 22. We have made cuts to the list of packages so that we can maintain our SLA for free disk space. This may break your workflows if you depend on certain packages that have been removed. Please review this list to see if you are using any affected packages.

Artifacts v3 brownouts

Artifact actions v3 will be closing down by January 30, 2025. To raise awareness of the upcoming removal, we will temporarily fail jobs using v3 of actions/upload-artifact or actions/download-artifact. Builds that are scheduled to run during the brownout periods will fail. The brownouts are scheduled for the following dates and times:

  • January 9, 12pm – 1pm EST
  • January 16, 10am – 2pm EST
  • January 23, 9am – 5pm EST

Changes to workflow validation for pull requests originating from forked repositories

Currently, you can prevent Actions workflows from automatically running on pull requests made from forked repositories. Actions evaluates whether the actor initiating the request is trusted based on the repository’s settings. Effective today, Actions will require validation of both the pull request author and the event actor to determine if a workflow should run from a pull request event originating from a forked repository. For more information on for pull request approvals, see our documentation.

New webhook rate limit

As GitHub continues to invest in availability, GitHub Actions is introducing a new webhook rate limit per repository. Each repository is now limited to 1500 triggered events every 10 seconds. For more details about the new webhook rate limit, please refer to our documentation.

Updates to the network allow list for self-hosted runners and Azure private networking

With the upcoming GA of Immutable Actions, Actions will now be stored as packages in the GitHub Container Registry. Please ensure that your self-hosted runner allow lists are updated to accommodate the network traffic. Specifically, you should allow traffic to ghcr.io and *.actions.githubusercontent.com. If you require more specific domains, you can use pkg.actions.githubusercontent.com instead of *.actions.githubusercontent.com.

This update also affects runners in all versions of GitHub Enterprise Server that use the GitHub Connect feature to download actions directly from github.com. Customers are advised to update their self-hosted runner network allow lists accordingly. For further guidance on communication between self-hosted runners and GitHub, please refer to our documentation.

Additionally, our guidance for configuring Azure private networking has been updated to account for the the new domains. The following IP addresses have been added to the NSG template in our documentation.

Copilot subscription-based network routing is now enforced

Network requests for Copilot are routed based on a user’s Copilot subscription. Requests for Copilot Individual, Copilot Business, and Copilot Enterprise users now route through different endpoints.

This change enables Copilot Business and Copilot Enterprise customers to make sure all Copilot users on their networks are accessing Copilot through their Copilot Business or Copilot Enterprise subscription, and that all Copilot user data is handled according to the terms of their Copilot Business or Copilot Enterprise agreement. In essence, customers will be able to use their network firewall to explicitly allow access to Copilot Business or Copilot Enterprise, and/or block access to Copilot Individual.

Today we enabled enforcement of the user’s subscription on the new endpoints, ensuring only Copilot Business users can connect to Copilot Business endpoints and only Copilot Enterprise users can connect to Copilot Enterprise endpoints.
