Breaking changes

This major release introduces three breaking changes that may require updates from consumers of @mdn/browser-compat-data.

1. Removal of null and true version values (#24174)

Previously, the version_added, version_removed and version_last fields allowed null (indicating support is unknown) and true (indicating support added/removed in an unknown version).

Now, these values have been removed from the schema. All existing instances have been replaced with explicit or ranged version numbers (e.g. “≤37“).

Impact: Consumers handling null or true values may need to update their code.

2. Improved TypeScript definitions for array values (#26172)

Several fields, such as notes, accept either a single value or an array of at least two values.

Previously, TypeScript definitions used string | string[], requiring consumers to validate array values manually.

Now, these types are more precisely defined as string | [string, string, ...string[]], ensuring that arrays contain at least two values when used.

Impact: Consumers validating array values may need to update their code.

3. New top-level manifests folder (#26109)

Previously, support data for the Web Application Manifest was placed under html/manifest, which inaccurately implied it was an HTML subfeature.

Now, a new top-level manifests folder has been created to host the Web Application Manifest under manifests/webapp to better reflect its independence, and to support future manifest types like the Payment Method Manifest.

Impact: Consumers referencing Web Application Manifest data may need to update their code.
