My local Jenkins alerts me regularly about new Jenkins releases and links to the Jenkins changelog at https://jenkins.io/changelog/. That changelog often does not contain the changes of the version announced (yet). Therefore I cannot take an informed decision about whether I need to upgrade or not.
Example: The alert says 2.183 is available right now while I write this. The changelog only contains 2.182 and earlier. By tomorrow the changelog might be updated, so I will also defer my local upgrade at least until tomorrow.
