GitHub Dependabot open-pull-requests-limit 0 disables version updates official documentation

💡 Result:

<search_synthesis>
Yes, setting open-pull-requests-limit to 0 in your Dependabot configuration effectively disables version updates for that specific package ecosystem [1][2][3]. According to official GitHub documentation, this configuration allows you to exclude version updates while still allowing Dependabot to process security updates for the same package manager [2][3]. Because security updates are managed independently and are not subject to this limit, setting the value to 0 ensures that Dependabot only creates pull requests for security vulnerabilities rather than for routine dependency version upgrades [1][2][4].

Users with write access Copy as Markdown ## In this article ## Managing Dependabot security updates for your repositories You can enable or disable Dependabot security updates for all qualifying repositories owned by your personal account or organization. For more information, see Managing security and analysis features or Managing security and analysis settings for your organization. You can also enable or disable Dependabot security updates for an individual repository. ### Enabling or disabling Dependabot security updates for an individual repository On GitHub, navigate to the main page of the repository. Under your repository name, click Settings. If you cannot see the "Settings" tab, select the dropdown menu, then click Settings. In the "Security" section of the sidebar, click Advanced Security. To the right of "Dependabot security updates," click Enable to enable the feature or Disable to disable it. For public repositories, the button is disabled if the feature is always enabled. ## Grouping Dependabot security updates into a single pull request In order to use grouped security updates, you must first enable the following features: - Dependency graph. For more information, see Enabling the dependency graph. - Dependabot alerts. For more information, see Configuring Dependabot alerts. - Dependabot security updates. For more information, see Configuring Dependabot security updates. Note When grouped security updates are first enabled, Dependabot will immediately try to create grouped pull requests. You may notice Dependabot closing old pull requests and opening new ones. You can enable grouped pull requests for Dependabot security updates in one, or both, of the following ways. - To group as many available security updates together as possible, across directories and per ecosystem, enable grouping in the "Advanced Security" settings for your repository, or in "Global settings" under Advanced Security for your organization. - For more granular control of grouping, such as grouping by package name, development/production dependencies, SemVer level, or across multiple directories per ecosystem, add configuration options to the`dependabot.yml` configuration file in your repository. Note If you have configured group rules for Dependabot security updates in a`dependabot.yml` file, all available updates will be grouped according to the rules you&`#39`;ve specified. Dependabot will only group across those directories not configured in your`dependabot.yml` if the setting for grouped security updates at the organization or repository level is also enabled. ### Enabling or disabling grouped Dependabot security updates for an individual repository On GitHub, navigate to the main page of the repository. Under your repository name, click Settings. If you cannot see the "Settings" tab, select the dropdown menu, then click Settings. In the "Security" section of the sidebar, click Advanced Security. Under "Dependabot," to the right of "Grouped security updates," click Enable to enable the feature or Disable to disable it. ### Enabling or disabling grouped Dependabot security updates for an organization You can enable grouped Dependabot security updates into a single pull request. For more information, see Configuring global security settings for your organization. ## Overriding the default behavior with a configuration file You can override the default behavior of Dependabot security updates by adding a`dependabot.yml` file to your repository. With a`dependabot.yml` file, you can have more granular control of grouping, and override the default behavior of Dependabot security updates settings. Use the`groups` optio…[truncated] <title>customizing-dependabot-security-prs</title> https://docs.github.com/en/enterprise-cloud@latest/code-security/how-tos/secure-your-supply-chain/manage-your-dependency-security/customizing-dependabot-security-prs 1. Check in a `dependabot.yml` file into the `.github` directory of your repository. For more information, see [Configuring Dependabot version updates](/en/enterprise-cloud@latest/code-security/how-tos/secure-your-supply-chain/secure-your-dependencies/configure-version-updates#enabling-dependabot-version-updates). 2. Set all the required keys. For more information, see [Required keys](/en/enterprise-cloud@latest/code-security/reference/supply-chain-security/dependabot-options-reference#required-keys). 3. If you want the customization for a package ecosystem to **only apply to security updates** (and exclude version updates), set the `open-pull-requests-limit` key to `0`. ... In this example, the `dependabot.yml` file: ... * Uses a private registry for updates to npm dependencies. * Disables version updates for dependencies, so that any customizations apply to security updates only. * Is customized so that Dependabot applies custom labels to the pull requests and automatically adds assignees. * Groups security updates for golang dependencies into a single pull request. ... updates: - package-ecosystem: "npm" directory: "/src/npm-project" schedule: interval: "daily" # For Lodash, ignore all updates ignore: - dependency-name: "lodash" # Disable version updates for npm dependencies open-pull-requests-limit: 0 registries: # Ask Dependabot to use the private registry for npm - example # Raise all npm pull requests for security updates with custom labels labels: - "npm dependencies" - "triage-board" # Raise all npm pull requests for security updates with assignees assignees: - "user-name" - package-ecosystem: "gomod" directories: - "**/*" schedule: interval: "weekly" open-pull-requests-limit: 0 groups: # Group security updates for golang dependencies # into a single pull request golang: applies-to: security-updates patterns: - "golang.org*" ... example, the `dependabot.yml` file: ... * Is customized so that Dependabot adds custom labels to both version updates and security updates. * Uses the `groups` customization option to create two groups ("`angular`" and "`production-dependencies`") in order to group multiple updates into single pull requests. * Specifies that the `groups` customization for `angular` applies to security updates only. * Specifies that the `groups` customization for `production-dependencies` applies to version updates only. ... # Raise all npm pull requests for security and version updates with custom labels labels: - "npm dependencies" - "triage-board" groups: angular: # Group security updates for Angular dependencies into a single pull request applies-to: security-updates patterns: - "`@angular`*" production-dependencies: # Group version updates for dependencies of type "production" into a single pull request applies-to: version-updates dependency-type: "production" <title>Dependabot options reference</title> https://docs.github.com/en/enterprise-server@3.21/code-security/reference/supply-chain-security/dependabot-options-reference ## `open-pull-requests-limit` ... Change the limit on the maximum number of pull requests for version updates open at any time. ... Dependabot default behavior: ... - If five pull requests with version updates are open, no further pull requests are raised until some of those open requests are merged or closed. - Security updates have a separate, internal limit of ten open pull requests which cannot be changed. ... When `open-pull-requests-limit` is defined: ... - Dependabot opens pull requests up to the defined integer value. A large value can be set to effectively remove the open pull request limit. - You can temporarily disable version updates for a package manager by setting this option to zero, see Disabling Dependabot version updates. <title>Result 5</title> https://docs.github.com/en/code-security/concepts/supply-chain-security/dependabot-pull-requests # Dependabot pull requests Understand the frequency and customization options of pull requests for version and security updates. ## Pull requests for security updates If you&`#39`;ve enabled security updates, pull requests for security updates are triggered by a Dependabot alert for a dependency on your default branch. Dependabot automatically raises a pull request to update the vulnerable dependency. Each pull request contains everything you need to quickly and safely review and merge a proposed fix into your project. This includes information about the vulnerability like release notes, changelog entries, and commit details. Details of which vulnerability a pull request resolves are hidden from anyone who does not have access to Dependabot alerts for the repository. When you merge a pull request that contains a security update, the corresponding Dependabot alert is marked as resolved for your repository. For more information about Dependabot pull requests, see Managing pull requests for dependency updates. > [!NOTE] > It&`#39`;s good practice to have automated tests and acceptance processes in place so that checks are carried out before the pull request is merged. This is particularly important if the suggested version to upgrade to contains additional functionality, or a change that breaks your project&`#39`;s code. For more information about continuous integration, see Continuous integration. ### Customizing pull requests for security updates You can customize how Dependabot raises pull requests for security updates, so that they best fit your project&`#39`;s security priorities and processes. For example: - Optimize Dependabot pull requests to prioritize meaningful updates by grouping multiple updates into a single pull request. - Apply custom labels to integrate Dependabot&`#39`;s pull requests into your existing workflows. Similar to version updates, customization options for security updates are defined in the `dependabot.yml` file. If you have already customized the `dependabot.yml` for version updates, then many of the configuration options that you have defined could automatically apply to security updates, too. However, there are a couple of important points to note: - Dependabot security updates are always triggered by a security advisory, rather than running according to the `schedule` you have set in the `dependabot.yml` for version updates. - Dependabot raises pull requests for security updates against the default branch only. If your configuration sets a value for `target-branch`, then the customization for that package ecosystem will only apply to version updates by default. For more information, see Customizing pull requests for Dependabot security updates. ## Pull requests for version updates For version updates, you specify how often to check each ecosystem for new versions in the configuration file: daily, weekly, or monthly. When you first enable version updates, you may have many dependencies that are outdated and some may be many versions behind the latest version. Dependabot checks for outdated dependencies as soon as it&`#39`;s enabled. You may see new pull requests for version updates within minutes of adding the configuration file, depending on the number of manifest files for which you configure updates. Dependabot will also run an update on subsequent changes to the configuration file. To keep pull requests manageable and easy to review, Dependabot raises a maximum of five pull requests to start bringing dependencies up to the latest version. If you merge some of these first pull requests before the next scheduled update, remaining pull requests will be opened on the next update, up to that maximum. You can change the maximum number of open pull requests by setting the `open-pull-requests-limit` configuration option. To further reduce the number of pull requests you may be seeing, you can use the `groups` configuration option to group sets of dependencies together (per package ecosystem). De…[truncated]

Use a positive Cargo cap unless version updates must be disabled.

open-pull-requests-limit: 0 disables all Cargo version-update pull requests. It does not create a zero-sized queue. Security update pull requests are not subject to this limit. Use the approved positive cap if routine Cargo updates must remain enabled.
