If you check the release announcement for the current build, that has a brief summary of what's available for the new update: https://runneroo.itch.io/on-your-day-off/devlog/654831/on-your-day-off-v04-relea...
Although, for the sake of improvement and wanting to make the overall experience of the game better, would it help to have more detailed release notes? I'm working on developing an online wiki (to be launched with the V0.5 build and to replace the PDF play-through guide) and I'm strongly considering adding more detailed release notes as a feature to that.
