I enjoy having a copy of the history in slack. What I do is have all jenkins deploys send a record to the #deploys channel (Service X, version Q deployed by person Y completed successfully in Z minutes), which comes for free with a tiny jenkins plugin. However one of the unicorns I worked at deleted all slack messages after 3 months for legal reasons, as one example. Also, slack has periodic outages. I think a lot of people underutilize jenkins, but once you're handy with it (and get over its god-awful ui) you never go back.
