So that just sounds like a team event, which I try to do once a month just to help keep the team connected.

I think the difference is internal vs external release then. Our internal releases were generally "nice job" and the like, as we completed sprints. It was still a clear recognition of something being completed. The actual external facing launch that the company cared about, the 'go live', was more what I was referring to, and which never really meant much, to me at least.
