Compatibility Notes

With any new release, certain features preclude prior default functionality. FairCom DB V12 introduces several new advances that may impact your prior c-tree experience. Notably in this release is a new default folder layout simplifying access to c-tree components. A major change to default IFIL path handling is also included. Be sure to review this entire list and verify any specific changes that apply to your usage.

As always, V12 is a major version release change. It is expected to thoroughly test existing application functionality before deploying a new server version and to follow all recommended upgrade procedures as described. Contact your local FairCom support team with any questions about compatibility and suggested upgrade steps.
