- **changed** — DayGrid with large number of events when dayMaxEvents:true now only inserts a necessary subset of events into the DOM instead of all events
- **changed** — Event render hooks like eventContent will now only run on a subset of events in DayGrid with dayMaxEvents:true
- **added** — DayGrid event slicing now includes better event packing with smarter positioning decisions for fewer slices
- **added** — DayGrid event slices now have more similar y-coordinates when related
- **fixed** — Events in DayGrid no longer unnecessarily go to +more link when higher-level slot would accommodate
- **fixed** — Events with custom ordering and eventOrderStrict:true can no longer overlap when slotEventOverlap is false
- **fixed** — Overlapping events no longer have tiny width when event content is not visible
- **fixed** — In Timeline and TimeGrid with custom eventOrder, DOM order now respects start-time first, then eventOrder for better accessibility and sequential event tabbing
- **fixed** — DayGrid events are no longer permanently invisible in React StrictMode
- **fixed** — Timeline view scrolling is now smoother when virtualized, especially with trackpad and irregular height resource rows
- **fixed** — Timeline view now accounts for DST in timeslots
- **fixed** — Resource TimeGrid/DayGrid filterResourcesWithEvents now excludes columns
- **added** — Print rendering now includes business-hours for print-previews that enable it
- **fixed** — Print rendering now has better page-wrapping of tall DayGrid rows with many events
- **fixed** — Print rendering now has better page-wrapping of tall Resource-Timeline rows with many events
- **fixed** — Events are now visible when printing using window.print()
- **changed** — General performance improvements with option-changes
- **changed** — Users of @fullcalendar/preact must upgrade their preact peer dependency to >=10.29.8
- **fixed** — Screen-reader improvement for Resource-Timeline timeline header text

###### 🎨 Event Rendering

- PERF: DayGrid with large number of events, when `dayMaxEvents:true` (limited by natural row height), only a necessary *subset* of events will be DOM-inserted, not all
  - BREAKING: As a result, a *subset* of events will be run through event render hooks like `eventContent`
- DayGrid event slicing
  - FEATURE: Better event packing, including smarter positioning decisions for fewer slices
  - FEATURE: Related slices have more similar y-coordinates
  - FIX: Events unnecessarily going to +more link when higher-level slot would accommodate
- TimeGrid event positioning
  - FIX: Events with custom ordering and `eventOrderStrict:true` can overlap with `slotEventOverlap: false` (#7914)
  - FIX: Overlapping events can have tiny width when event content not visible (#7879)
- FIX: In Timeline and TimeGrid, when custom `eventOrder`, DOM order respects start-time first, then `eventOrder`. Better for a11y and tabbing through events sequentially
- FIX: React StrictMode: DayGrid events permanently invisible (#8088)

###### 👥 Resource Views

- FIX: Timeline view, smoother virtualized fast scrolling, especially with trackpad and especially while scrolling *up* with irregular height resource rows
- FIX: Timeline view, account for DST in timeslots (#7620)
- FIX: Resource TimeGrid/DayGrid, `filterResourcesWithEvents` should exclude columns (#6149)

###### 🖨 Print Rendering

- FEATURE: Print renders business-hours for print-previews that enable it
- FIX: Better page-wrapping of tall DayGrid rows with many events
- FIX: Better page-wrapping of tall Resource-Timeline rows with many events
- FIX: Events are not visible when we print using `window.print()` (#8097)

###### 🧹 Misc

- PERF: General improvements with option-changes. Users of `@fullcalendar/preact` must upgrade their `preact` peer dependency to >=10.29.8
- FIX: Screen-reader improvement for Resource-Timeline timeline header text
