 ## [Unreleased]
 
+## [0.4.0] - 2026-09-18
+
+### Added
+
+- Show local-day read and write totals with their recorded timezone, labelled as totals so far for the current day.
+- Open the dashboard on a live three-hour written-volume graph with a read/write toggle and selected-point inspection.
+- Browse history by day from the keyboard with `[`, `]`, `g` date entry, and `t` for today and the live view.
+
+### Changed
+
+- Collect every three minutes on systemd and runit, plot live points at their actual timestamps, and retain three-minute detail for 14 days before durable summaries.
+- Withhold the endurance outlook until one full local observation day has usable evidence, then show it with categorical confidence.
+
+### Fixed
+
+- Keep midnight-spanning activity once as shared boundary evidence instead of adding it to both days.
+- Publish derived hour and day history consistently with each collection run.
