Since February 2026, we have started a new versioning and support process for frontend consent libraries. This makes it easier for you to understand library changes, choose a specific version, and plan for updates.
How versioning works
Each version has three numbers:
1.0.0= major release1.1.0= minor release1.1.1= patch release
Major release
A major release includes breaking changes, such as incompatible API changes.
Minor release
A minor release adds new features in a backward-compatible way.
Patch release
A patch release includes bug fixes and small improvements in a backward-compatible way.
Libraries released before versioning
Libraries served before we introduced versioning are treated as version 1.0.0.
These libraries are frozen. They are no longer updated and are no longer supported through the versioned delivery path.
The first fully supported versioned release is 1.1.0.
Default library URL
If you use the default library snippet URL, you automatically receive new minor and patch releases: https://policy.app.cookieinformation.com/uc.js.
Major releases may also be published to this URL. Before that happens, we will announce the migration period in advance so you have time to test and update your implementation.
Use a specific version
If you want to load a fixed version, include the version number in the script URL: https://policy.app.cookieinformation.com/v1.1.0/uc.js.
You can verify the loaded version in your browser’s developer tools.
Version support
We support the three latest major versions. For example, if the current default release is 4.x.x, we support:
4.x.x3.x.x2.x.x
If you use a fixed version, we will let you know before that version reaches the end of support, so you have time to migrate.
Version usage reporting
We also use a reporting mechanism to track which library version is being used through an additional URL query parameter.
