## Unreleased (development workspace)
- Frontend (Settings → Events): Added Presentations defaults (slideshow interval, page-progress, auto-progress) with load/save via `/api/system-settings`; UI uses Syncfusion controls.
- Backend defaults: Seeded `presentation_interval` ("10"), `presentation_page_progress` ("true"), `presentation_auto_progress` ("true") in `server/init_defaults.py` when missing.
- Data model: Added per-event fields `page_progress` and `auto_progress` on `Event`; Alembic migration applied successfully.
- Event modal (dashboard): Extended to show and persist presentation `pageProgress`/`autoProgress`; applies system defaults on create and preserves per-event values on edit; payload includes `page_progress`, `auto_progress`, and `slideshow_interval`.
- Scheduler behavior: Now publishes only currently active events per group (at "now"); clears retained topics by publishing `[]` for groups with no active events; normalizes naive timestamps and compares times in UTC; presentation payloads include `page_progress` and `auto_progress`.
- Recurrence handling: Still queries a 7‑day window to expand recurring events and apply exceptions; recurring events only deactivate after `recurrence_end` (UNTIL).
- Logging: Temporarily added filter diagnostics during debugging; removed verbose logs after verification.
- Documentation: Updated `.github/copilot-instructions.md` and `README.md` to reflect presentation defaults, per‑event flags, scheduler active‑only publishing, retained‑topic cleanup, and UTC normalization.
- Release metadata: Program info bumped to `2025.1.0-alpha.12`; changelog entries focus on UI‑facing changes, backend/internal notes removed from user-facing entries.

Note: These changes are available in the development environment and may be included in future releases. For released changes, see TECH-CHANGELOG.md.
