Calendar plugin (webmail_plugin_calendar, non-removable core plugin): - Local calendars/events CRUD with RLS isolation; recurrence expanded at query time (DST-correct), EXDATE + detached-override merge. - Calendar app bundle: month/week/day/3-day views, mini-month, event form (color, show-as, timezone combobox, repeat, reminders, guests w/ recipient autocomplete, Jitsi video call), event popover with RSVP badges, resizable/ collapsible left panel + theme toggle, overlap layout. - iMIP invites: sdk.mail sends REQUEST from the organizer's mailbox (HTML + text/calendar + invite.ics); public /rsvp endpoint (vault-sealed token) records accepted/declined/tentative per attendee. - "This and following" edit + scoped delete (this / this-and-following), with a delete confirmation dialog for recurring events. Core: - Settings: time_format (12/24h, default 24h) + jitsi_server; new Integrations section; date order follows time format (en-GB vs en-US) across Mail. - Plugin SDK: mail (send from a user's account), vault (envelope encrypt), multi-method SSRF-guarded http; AppSwitcher product switcher; full-bleed PluginPage. Mail HTML rendering: - Sanitizer allows <style> blocks + class (CSS sanitized: drop script-like, strip @import/url() when remote images blocked); SANITIZER_VERSION 3 so already-indexed mail re-sanitizes on view. - Attachments: a Content-Disposition: attachment part is a real attachment even when it also carries a Content-ID (fixes hidden invite.ics).
