Release 8.52

This release brings self-service scheduling to App Suite, makes it quicker to organize and find mail, and moves settings and notifications into side panels, alongside accessibility and performance improvements throughout.

• Appointment Polls: Propose a set of possible times and share the poll's link. Invitees vote yes, no or maybe in their own time zone without needing an App Suite account, and picking the winning time closes the poll, creates the appointment and invites everyone who took part.
• Appointment Booking: Publish what can be booked and when, and let others pick a free time from a public booking page. Confirmed bookings arrive in both calendars as ordinary invitations, and can be rescheduled or cancelled from a link in the confirmation mail.
• Categories from a searchable dropdown: Type to filter the list, or type a new name to create the category and apply it in one step. The same picker assigns categories to mails, appointments, contacts and tasks, and filters searches by category.
• Sortable mail search results: Search results can now be sorted and ordered like a normal folder, by sender, subject or size rather than only by date. Cancelling the search restores the folder's own sort order.
• Drag and drop emails out of the browser: Messages can be dragged from App Suite into other applications, and EML files can be brought back in by dropping them onto App Suite.
• Settings and notifications as side panels: The settings menu and notifications now open in a side panel instead of a floating popover, with keyboard focus moving into the panel as it opens and returning to the button that opened it on close. Calendar reminders and invitations offer a “Show in calendar” link that highlights the appointment in the current view.

A detailed list of changes can be found in the changelogs.
