v1.3.0

Added

- Preview calendar imports with event selection, compatibility details, duplicate detection, cancellation, per-event results, retry, and session undo for unchanged imported events. Series that cannot be fully verified remain in Calendar with an explanation.
- Import supported advanced repeating rules and edited occurrences as complete series.
- Export multiple calendars as separate files or a combined ICS file; choose all dates, the next 12 months, or a custom inclusive date range. Bounded exports contain individual occurrences.
- Open ICS documents from Files and other apps, with a choice of editing or importing.
- Save named drafts, search and rename library entries, and display persistence failures without overwriting unreadable files.
- Choose weekly days and ordinal monthly recurrence patterns.
- Show Server Mode connection activity, troubleshooting steps, and a diagnostic report without calendar content or credentials.
- Provide Create ICS from Template and Export Calendar to ICS actions in Shortcuts.

Fixed

- Fix Server Mode calendar moves when clients keep the event filename or use non-UUID filenames, including MOVE requests and creating the destination event before deleting the source.
- Keep moved events editable, preserve client filenames across restarts, and report moves and renames correctly during incremental synchronization without duplicate entries.
- Distinguish calendar conflicts from failed request conditions in Server Mode diagnostics instead of reporting every conflict as an event changed by another client.
- Keep all-day events without an explicit end date to one day; consume DURATION correctly, including daylight-saving changes, and reject malformed dates.
- Preserve imported meeting methods and attendee response, role, RSVP, and organizer metadata.
- Use shared time-zone serialization for single-event and calendar exports.
- Extract calendar writing and file operations from the editor and retire its duplicate private ICS parser and writer.

What’s New for 1.2.2:

• Export a selected calendar to one ICS file, including repeating events and edited occurrences. Save it to Files or share it with another app.
• Get straight to Create Events, Edit Events, Export Calendars, Import Calendars, or Server Mode from the new home screen.
• Search and choose an event from a multi-event ICS file, then edit and save it separately.
• Improved handling of reminders, repeating all-day events, and time zones in calendar exports.

ICS Creator is now ICS Toolkit.

This release adds reminders, explicit time-zone selection, compatibility review and raw ICS preview, autosaved drafts, and reusable templates. Imports now retain more calendar metadata, including advanced recurrence rules, exceptions, alarms, categories, status, visibility, and attachment details. Meeting validation and stable event UIDs make invitation updates safer and more reliable.
