This update brings native Mac toolbar improvements and connection stability refinements. • Mac Window Toolbar: Quick search (⌘F) and responsive navigation controls tailored for macOS. • Connection Resilience: Improved handling of network transitions and background suspension during contact browsing. • Interface & Sign-In Polish: Refined sign-in buttons with native icons and updated status presentation.

This update improves contact viewing and provider connections. • Improved CardDAV contact loading and handling of incomplete server responses. • Give provider connections your own names so they are easier to recognize. • Improved contact-list stability when switching apps and returning. • Refined permission guidance and interface layout.

This update delivers incremental synchronization, expanded directory support, and stability refinements across iPhone, iPad, and Mac. • **Incremental CardDAV Sync**: Quicker and more efficient contact updates using incremental sync tokens. • **Directory & Server Compatibility**: Enhanced connection handling for corporate directories and custom servers. • **Interface & Performance Polish**: Smoother list browsing, optimized memory usage, and refined account setup flows. • **General Reliability**: Under-the-hood stability fixes and improved responsiveness across all supported devices.

This update delivers synchronization engine improvements, accurate contact count tracking, and usability polish across iPhone, iPad, and Mac. • **Hardened CardDAV Sync**: Coalesced change merging and deterministic duplicate UID resolution for smoother, uninterrupted imports. • **Accurate Contact Counts**: Contact list headers now properly exclude pending or remotely deleted records. • **Empty State Pull-to-Refresh**: Seamless pull-to-refresh gesture support even when your address book is initially empty. • **Connection Stability**: Enhanced server discovery compatibility for Nextcloud, iCloud, and custom CardDAV servers. • **General Polish**: Concurrency hardening, interface refinements, and bug fixes.

This update adds explicit Calendar destinations and flexible contact-date reminders, alongside large-library merge, backup, and contact-detail reliability improvements across iPhone, iPad, and Mac. • **Calendar Destinations**: When adding a birthday or custom contact date to Calendar, choose an on-device calendar or a writable provider calendar already configured on the device. Local-only and protected contacts show an extra privacy confirmation. • **Birthday & Important-Date Reminders**: Manage birthdays and other contact dates separately, choose recurrence and advance notice, and use per-contact or batch controls without changing the contact card. • **Large-Library Contact Merging**: Fine-tuned the mathematical merge process for smoother grouping, comparison, and safe deduplication across huge contact collections. • **Cloud Backup & Restore**: Improved scheduled backup reliability, progress tracking, and restore status visibility. • **Contact Provider Management**: Smoother account status refresh and provider connection handling directly from the Accounts page. • **Contact Detail Reliability**: Resolved minor repeated-detail cleanup glitches and improved view responsiveness during heavy edits. • **General Polish**: Minor bug fixes, memory optimizations, and translation refinements.

This update introduces a more efficient mathematical merge algorithm for very large contact libraries, alongside safer backups and clearer account management across iPhone, iPad, and Mac. • **Large-Library Contact Merging**: A new mathematically optimized merge process groups and compares huge contact collections efficiently, reducing duplicate work while preserving contact data. • **Cloud Backup Scheduling**: Configure automatic backup frequency, monitor progress, and review restore results without leaving the app. • **Contact Provider Management**: Manage contact services directly from the Accounts page, with clearer actions for adding and maintaining providers. • **Contact Detail Reliability**: Improved repeated-detail cleanup, loading states, and contact actions so edits remain available while details continue organizing. • **Localization & Stability**: Refined translations, including Tibetan, plus fixes across backup, sync, navigation, and account workflows.

This update delivers an enhanced multi-column split view experience on iPad and macOS, stronger CardDAV sync safety, and navigation refinements across all contact management workflows. • **iPad & Mac Sidebar Navigation**: Native double-column split view layout with an Ive-style sidebar for instant access to accounts, smart tools, backup vaults, and relationship filters. • **Thread-Safe Cloud Sync**: Hardened asynchronous CardDAV synchronization with thread-safe Core Data context isolation for rock-solid background sync. • **Batch Operation Navigation**: Streamlined bulk edit and address scan workflows with responsive cancel and pop-to-parent navigation controls. • **Visuals & Stability Polish**: Updated UI rendering, improved avatar loading, and optimized responsiveness across iPhone, iPad, and macOS.
