Restored calendar sharing in direct and group conversations so everyone can compare availability and find time together. This update also improves shared-calendar account matching and uses clearer cloud wording throughout the app.

Messaging is smoother and more dependable. • Messages stay in chronological order. • Conversation previews consistently show the latest received message. • Unread indicators stay accurate. • Chats open at your last-read position by default, with a setting to open at the newest message. • Group availability makes complex schedules and near matches easier to understand. • Calendar synchronization and recurring events are more reliable.

Flexi 5.3 restores dependable group messaging and makes conversations easier to scan. • Group chat messages now send reliably • Direct messages remain private and dependable • Conversation previews show the latest message on your device instead of a generic encrypted-message label • Message preview text is derived locally while encrypted content remains protected end to end • Additional messaging performance and reliability improvements

Flexi 5.2 focuses on speed and reliability across messaging and calendar sync. Group chats now load and respond much faster, message updates and encryption work are processed more efficiently, and conversation lists, search, avatars, events, and RSVPs avoid unnecessary work. Calendar synchronization is more responsive and resilient across Apple and Google calendar workflows, including recurring events, reminders, external edits, and deletion handling. This update also improves account-switch safety and message/event recovery while preserving end-to-end encryption and existing group features.

Flexi 5.1 makes messaging more reliable from first contact through long-running conversations. People with Flexi now shows verified users from your authorized address book instead of a global directory or old-chat cache. Failed sends keep their text and can be retried, read receipts survive connection changes, older history can be loaded and searched privately on-device, and conversations can be archived without deleting shared history. Trusted devices can approve end-to-end encrypted history recovery for a new device without sending private keys or plaintext through Firebase. This update also improves group creation, member management, notifications, message ordering, account switching, and security checks throughout direct messages, groups, events, and RSVPs.

Groups are now built for planning: name conversations, assign moderators, set member nicknames, manage permissions, share availability, create events, add them to Apple Calendar, and RSVP Going, Maybe, or Can't Go. The next event stays visible at the top of the chat. Version 5.0 also adds end-to-end encryption for new messages and event details, plus reporting, blocking, targeted content filtering, group-leaving, and account-deletion controls.
