At Pitch, there is a #shipped Slack channel, where engineers post any user-visible changes to the product they deployed to the internal build. The Slack messages include a short description, link to the Git changeset, and often a screenshot or even video.

It’s great to have changes to the product so visible. It encourages people to try out new and enhanced features, which is excellent for dogfooding. Slack threads provide a great way to discuss the changes in more detail, if necessary.

It is also used for release notes: the people writing release notes have an exact list of all the changes they can include in the release notes.
