KANBAN Board - Releasing "done" items

[Theme Grenz]

We currently have 211 items Done on the Kanban.  We would like to release these in individual "packages" based on (sprint).  How do we filter the 211 items by sprint prior to releasing?     

[Nic Brough -Adaptavist-]

You don't.  An issue is either done, or you're still working on it.

Kanban is not really that focussed on distinct and discrete release packaging.  The giveaway in your question here is you've mentioned "sprint".  If you're doing Sprints, you're not doing Kanban.  I suspect your only option is to release as per Scrum or Kanban, whichever suits you better and then have someone add package versions later (or before, if you do it as a custom field instead of a version)
