Deleting an event the user organizes, with other guests, asks "Would you like
to inform the participants that this event is canceled?" (Yes, inform them and
delete / No, just delete / Cancel; for a recurring one after which occurrences).
Yes sends each guest an iTIP CANCEL from the organizer's mailbox — of one
occurrence via RECURRENCE-ID — or, for "this and following", the shortened
series. Invitations now carry their RRULE, so recurring events repeat for
guests too.
An organizer's cancellation is applied as the email arrives (message.new hook)
or, for older mail, when the card is opened — always, whatever the settings:
only from that event's organizer and not older than the calendar's copy; one
occurrence becomes an EXDATE. The card says "Event was removed from calendar".
Settings → Calendars → Invitations now work, defaulting to "Do not
automatically update my calendar": "Only update events that I have already
added" applies the organizer's changes (keeping the user's answer), "Add new
events…" also adds new invitations, unanswered — from contacts or anyone — to
the chosen calendar, and "mark as read and file" archives such messages. With
no automatic updates, a changed invitation says so on its card.

Invitations received by email (iMIP): above the message body, a card with
when, what, where (or "Join video call"), the organizer, what else is in the
calendar then (a conflict, else the previous event that day), and Yes / No /
Maybe. Yes and Maybe put the event in the calendar (or update it), No takes
it out — and is still shown as the answer given; each sends the organizer
the iTIP REPLY, then a "Reply sent" toast, and an open calendar refreshes.
A cancellation offers "Remove from calendar". It is the calendar plugin's
message.banner slot (ui/invite.js, imip.py, /invitations endpoints); the SDK
gains the user's own accounts and settings. An Outlook-style invitation sent
only as text/calendar is now kept as invite.ics too.
Calendar: clicking an empty day in the side panel's agenda opens a new event
on that date; a video-call link can be removed (✕ beside Copy); the page
guests see after answering, and our invitations' footer, say Ultimo Calendar
(with the logo).
Attachments: videos (mp4, mov, webm, …) play in the full-screen preview,
paused until played; attachments are now served from disk with HTTP Range,
so a video starts at once and can be seeked.
People tab: everyone in the thread, the user included, A–Z, under the name
any message gives them. Initials circles share one colour rule in the list,
the reading pane and the People tab. The contact view drops its duplicate
"Message" button. A general corner toast (webmail:toast) joins Undo's.
