Release v2.23.0-beta.2 (#141)

The agenda opens on today, and scrolling up loads earlier days 30 at a time. Past days follow the past-events setting: Dim fades them, and with Hide the agenda still starts at today.

The agenda no longer picks up the day the month or day view was on, so "Next 30 days" always counts from today. That fixes the bug from the issue comment. It also means the agenda no longer follows the shared view date from #184 when you switch to it. Backing out of a day opened from the agenda keeps your scroll position.

Not in the issue: multi-day events that are still running now dim on the days already behind you, in the agenda, month, week and day views. Before, they stayed at full strength until the whole event ended. A spanning bar dims once the last day it covers in that row has passed.

The widget is unchanged and still starts at today.

Closes #367

 ## [Unreleased]
 
+### Added
+- **Long press an event to select it.** In the day, 3-day and week views, a long press lifts the event and selects it. Keep your finger down and move to drag it straight away. A selected event has handles at its top and bottom: drag them to change when it starts or ends, in 15-minute steps and across midnight if you want. The bar at the top edits, duplicates, shares or deletes it, and tapping elsewhere or going back deselects it. Read-only events can be selected but not moved or resized ([#141]).
+- **Scroll back to earlier days in the agenda.** Scroll up past today to see earlier days' events, loaded a month at a time. Past days follow the past-events setting: Dim fades them, and with Hide the agenda still starts at today ([#367]).
+
+### Fixed
+- **The agenda always starts today.** Coming from the month or day view, the agenda used to start at the day you had open there, so "Next 30 days" could show the 1st to the 30th of the month. It now opens on today with your chosen range. Backing out of a day you opened from the agenda still returns you to where you were ([#367]).
+- **Multi-day events dim on the days already behind you.** With past events dimmed, an event running over several days stayed at full strength on its earlier days until it ended. Those days now dim in the agenda, month, week and day views ([#367]).
+
+## [2.22.5] — 2026-10-07
+
+### Fixed
+- **Reopening the app the next morning shows the right day.** The month view used to mark yesterday as today and keep the day you picked the evening before selected, so you had to tap today to see its events. Every view now moves on to the new day at midnight and when you come back to the app. A view you browsed to another date stays where it is ([#373]).
+
+## [2.22.4] — 2026-10-07
+
+### Fixed
+- **Edits and deletions show up straight away on every phone.** On some phones, Samsung among them, an edited, moved or deleted event stayed where it was until the app was restarted, so a second edit could act on an event that had already changed. Calendula now refreshes its views itself after every change, and again when you come back to the app ([#364]).
+- **The home-screen widgets do less work per update.** The month widget loads the months around the one it shows instead of more than two years of events, and the agenda widget only its chosen range. This should help widgets that stayed on "loading" on slower phones ([#363]).
