Dependabot version updates introduce default package cooldown
Dependabot now waits until a new release has been available on its registry for at least three days before opening a version update pull request. This cooldown is now the default and requires no configuration.
Intelligence analysis by Llama

Dependabot has introduced a default package cooldown for version updates, which requires no configuration. This cooldown gives a signal time to surface, making it less likely to merge a bad release the moment it ships.
Imagine you're playing a game with your friends, and someone sends you a new level to play. But before you play it, you want to make sure it's not a trick level that will cheat you. Dependabot is like a friend who sends you new levels, but now it waits for a few days to make sure the level is safe before sending it to you.
Analysis
A Safer Update Process
Dependabot's new default package cooldown is a significant step towards reducing the risk of supply chain attacks. By introducing a short delay between new releases and version updates, Dependabot gives the signal time to surface, making it less likely to merge a bad release the moment it ships.
This change is particularly important for security updates, which still open immediately. Critical fixes are never delayed, ensuring that maintainers and the community have time to catch any compromised or broken versions.
Control Remains with the User
While the default cooldown applies to version updates across all supported ecosystems on github.com, users can still opt out or set a different window using the cooldown option in their .github/dependabot.yml file. This flexibility ensures that users remain in control of their update process.
Impact on Supply Chain Security
The introduction of a default package cooldown is a positive step towards improving supply chain security. By giving signal time to surface, Dependabot reduces the risk of supply chain attacks and makes the update process more secure. This change is particularly important for open-source projects, which often rely on maintainers and the community to catch and fix security issues.
Key points
- Dependabot now waits until a new release has been available on its registry for at least three days before opening a version update pull request.
- The default cooldown applies only to version updates, not security updates.
- Users can still opt out or set a different window using the cooldown option in their .github/dependabot.yml file.
This change will lead to a more secure update process, reducing the risk of supply chain attacks. Users will have more control over their update process, and the community will have more time to catch and fix security issues.
If not implemented correctly, the cooldown could lead to delayed updates, which might negatively impact users who rely on timely updates. Additionally, users who opt out of the cooldown might be more vulnerable to supply chain attacks.
