Upgrade to V4

Upgrading to 51Degrees version 4

To have access to the version 4 data files, you will need to upgrade to a new licence key. To do this, visit our Pricing page and select a paid product that suits your needs. Alternatively, get in touch with Sales if you require any help.

For further reading on what changes were made in Version 4, look at our GitHub profile for release notes or read one of our summary blogs.

Once you have obtained your new licence key, please visit our Migration guide for the next steps.
