Website and customer guides

The Cairn website, customer guides and email enquiry route are available. Use Help and support to ask a question, report a bug or share feedback. The website prepares an email for you to review and send; it does not create a private product support case.

Planned first pilot product release

No release tag, production URL or release date has been assigned. Required work includes managed sign-in, customer isolation, administration, durable operation, a real integration, protected evidence, controlled deployment, recovery and tested support.

Future entries must identify what actually changed, the supported versions, migration/recovery instructions, known limitations and the validation performed. A prepared feature or a passing internal test must not be described as a deployed customer capability.
