I only have one project configured in a server, and the only lifecycle defined (and used) has a custom retention policy defined (see attached screendump). However when deploying it is not being used - the log says:
| == Success: Apply retention policy on Tentacles ==
13:07:29 Info | Apply retention policies…
13:07:29 Verbose | Tentacle retention policy set to ‘keep all’
