HyperCloud 3.0.0 hypercal is now HyperCloud, a self-hosted personal cloud: calendar, tasks, scheduling polls, contacts and files, each an app the instance admin can switch on or off. Files arrives with sharing, groups and public links; devices link by approving a code in the browser; a desktop sync client keeps a folder in step with your files; and on Android, Contacts and Files are apps of their own beside Calendar, signed in through one HyperCloud account. Existing installs, Android apps and desktop profiles update in place. **HyperCloud.** The new name is everywhere a person sees it. Identifiers that existing installs depend on are kept: the Android package dev.hypercalendar.app, the desktop profile directory, the database and Docker image names and the .hypercalendar backup format (see the roadmap). Admins switch apps on and off in the dashboard; a switched-off app also leaves /dav and MCP. Prometheus metrics are named hypercloud_*, MCP resources hypercloud://. **Files.** Folders and files in a file manager: list and grid, filters and sorting, favorites and recent files, bulk move, copy and delete, downloads as a ZIP, thumbnails, viewers for pictures, text, video, audio and PDF, an upload dialog with progress and resumable uploads, the newest 20 versions of every file, and the Trash. Admins set the storage per account. Files are reachable over WebDAV at /dav/files/<user>/, and a file can be attached to an event. Contents live on disk beside the database (FILES_PATH, files/ by default), named by their SHA-256. Migrations 0051 and 0052. **Groups and sharing.** Admins keep groups of accounts. Share a file or folder with people or groups, to view or to edit, or make a public link with a password, an expiry and, for a folder, uploads by visitors. Migration 0053. **Devices.** Link a sync client or a phone by approving the code it shows in a browser where you are signed in (/connect); Settings > Devices lists the linked devices and unlinks them, which ends every token they hold. Migration 0054. **Desktop sync client.** hypercloud-sync keeps a folder on a Linux computer and your files the same, both ways, within seconds of a change on either side, with conflict copies instead of lost edits. It has a tray icon and a page of its own to set it up and follow it, and starts with your session. Install the .deb or .rpm from this release, or hypercloud-sync-bin from the pacman repository. **Android.** HyperCloud Calendar (this app, with tasks and polls) is joined by HyperCloud Contacts, HyperCloud Files and HyperCloud, the small app that holds your account so the others sign in with one tap. Contacts kept in the Calendar app move to the Contacts app through a banner. Each app carries only its own code and permissions. **Under the hood.** SQLite gets an explicit busy timeout and periodic PRAGMA optimize; app password use is written at most once a minute; new file contents are flushed to disk off the event loop. sharp 0.35.5 fixes the libvips, libheif and librsvg advisories; the desktop app runs on Electron 44.7.0.
