Versioning

Versioning is one of Renovate's core "module" types. The other modules are Platform, Manager and Datasource. Renovate uses the version module to answer questions such as:

  • Is this a valid version string?
  • Is this a valid constraint/range?
  • Does this version match with this constraint?
  • If the current constraint is X, what would the new constraint be if we updated to version Y?
  • Is this a major, minor or patch update?
  • Is this a breaking change?

How Renovate uses its core modules during a run:

  1. Renovate's Manager module extracts the dependencies
  2. Renovate's Datasource finds the versions of the dependencies
  3. Renovate's Versioning scheme sorts and filters the results

The "versioning" chosen can be different per package manager, because different package managers use different versioning schemes. For example, npm uses 1.0.0-beta.1 while pip uses 1.0.0b1.

Why you might need to manually configure versioning

Renovate interprets versions correctly out-of-the-box most of the time. But Renovate can't automatically detect all versioning schemes. So sometimes you need to tell the bot what versioning scheme it should use.

For some ecosystems, automatic version selection works nearly every time (e.g. for npm-compliant managers, use npm versioning). For other ecosystems such as Docker or GitHub tags, there is no consistent convention for versions, so the default choice may not always work. For example some Docker images may use SemVer, some PEP440, some Calendar Versioning, etc.

If the automatic version selection does not work for a dependency update: set the versioning for that dependency in the Renovate config file.

General concepts behind overriding versioning

  • Although you can reconfigure versioning per-manager or per-datasource, you probably don't need such a broad change
  • More commonly you would need to configure versioning for individual packages or potentially package patterns
  • The best way to do this is with packageRules, with a combination of matchManagers, matchDatasources, and matchPackageNames. Avoid configuring versioning in a rule that also uses matchUpdateTypes, as the update types aren't known at the time the versioning is applied

Examples of versioning overrides

Overriding Docker versioning to use a versioning specific for a package

The configuration below overrides Renovate's default docker versioning for the python Docker image and instead uses the pep440 versioning scheme to evaluate versions.

{
  "packageRules": [
    {
      "matchDatasources": ["docker"],
      "matchPackageNames": ["python"],
      "versioning": "pep440"
    }
  ]
}

Using a custom regex versioning scheme

{
  "packageRules": [
    {
      "matchPackageNames": ["foo/bar"],
      "versioning": "regex:^(?<compatibility>.*)-v?(?<major>\\d+)\\.(?<minor>\\d+)\\.(?<patch>\\d+)?$"
    }
  ]
}

Breaking Changes

In most ecosystems, especially SemVer, major upgrades are treated as breaking changes. But other updates may have breaking changes too, for example:

  • In SemVer, any update from a 0.x version may be breaking (including 0.1.0 -> 0.1.1, 0.1.0 -> 0.2.0 and 0.1.0 -> 1.0.0)
  • Updates from pre-release versions like 1.0.0-pre.1 to other versions (including stable versions like 1.0.0) can be breaking
  • Python makes breaking changes in minor updates, e.g. from 3.12 to 3.13

It can be tempting to propose ideas like "let's treat minor updates of Python as major updates" but that is swapping one problem for a worse problem. The definitions of major and minor should not be redefined and broken in order to shoehorn in the related concept of "breaking change". Instead, Renovate has the concept of isBreaking, which can be decided independently of updateType.

Here's an example of grouping all non-breaking updates together:

{
  "packageRules": [
    {
      "description": "Group non-breaking updates",
      "matchUpdateTypes": ["minor", "patch", "digest"],
      "matchJsonata": ["isBreaking != true"],
      "groupName": "Non-breaking updates"
    }
  ]
}
