Fixes for the Oak repository are delivered via Oak Cumulative Fix Packs (OCFP) which are fully supported, similarly to standard Cumulative Fix Packs. An Oak Cumulative Fix Pack is self-dependant (no dependencies). You need not worry about finding/resolving dependencies.
Install the latest cumulative fix pack for your AEM version to keep your deployment up-to-date.
If necessary, a diagnostic build on top of the latest OCFP can be made available for validation purpose before the official availability of the next OCFP. The precondition is that you have the latest OCFP running. A diagnostic build only provide the same level quality assurance as a hot fix, therefore it doesn't provide the same level of quality assurance as a cumulative fix pack, service pack, or product release. All official Oak fixes will be released as OCFP which come the with full support.
For more information on CFP and other types of releases, see Maintenance Release Vehicle.

Starting Oak 1.6.9, the Oak cumulative fix packs will be only delivered as part of the AEM cumulative fix packs.
