Feb 1, 2026February 2026 monthly highlights for mullvadvpn-app (mullvad/mullvadvpn-app). The primary focus was migrating the AddressCache from a legacy approach to a runtime-backed AddressCache, resulting in a simplified, more reliable caching lifecycle across the app, daemons, and API integrations. This included removing outdated AddressCache references, adjusting trait bounds, and integrating with the runtime-backed cache via new FFI calls and API changes. Concurrently, the team tightened safety and correctness in Rust through expanded safety annotations, added access method logging, and improved test reliability. Minor code quality improvements were performed via formatting cleanup and safety-related fixes. Additionally, targeted bug fixes improved runtime stability and maintainability. Key architecture/implementation changes: - AddressCache lifecycle overhaul: replaced legacy AddressCache usage with runtime-backed implementation; removed redundant references; adjusted trait bounds and daemon interactions; ensured AddressCache is non-dynamic backing as recommended. - FFI and API integration: introduced mullvad_api_update_address_cache FFI function for iOS Rust code and migrated Endpoints updates through Rust API rather than local trackers. - Runtime safety and observability: added safety annotations to unsafe Rust functions, expanded safety guarantees, and introduced access method logging; enhanced safety-related comments and formatting. - Testing and stability: MullvadRustRuntimeTests fixed to improve reliability; safety comments and typo fixes across safety annotations; minor formatting improvements for consistency. - Code quality: general code formatting cleanup to improve readability and maintainability.

Mar 1, 2025March 2025 – Mullvadvpn-app: Implemented three substantive UI/asset and state-management improvements that enhance scalability, clarity, and feature discoverability. No explicit bugs fixed in this scope. Key changes include a reusable SVG-based Vector Image Asset System with centralized image access, decoupled DNS UI visibility from content blockers, and dynamic Multihop feature visibility driven by user settings or tunnel state. These efforts reduce asset maintenance, simplify UI state management, and lay groundwork for future UI refreshes and scalability.

Nov 1, 2024November 2024 (mullvad/mullvadvpn-app): Delivered user-facing obfuscation controls and stability improvements that strengthen security posture and reduce maintenance risk. Implemented UDP-over-TCP obfuscation settings with a new SwiftUI UI for port selection, mutable settings state, a dedicated ViewModel, and integration into the VPN settings flow. Renamed the setting to udpOverTcp, removed legacy UDP port UI, and ensured coherence with the overall settings architecture. Added Shadowsocks obfuscation settings with its own UI and ViewModel, including automatic vs. custom port selection with validation. Fixed a critical robustness bug in SingleChoiceList to preserve user input when clearing a custom value. Refactored localization handling for SingleChoiceList to client-side, enabling better localization flexibility. Performed UI polish and code quality improvements including SwiftLint directive adjustments and re-enablement of checks to raise maintainability and developer velocity. These efforts collectively improve user control over obfuscation features, reduce risk in configuration flows, and demonstrate strong SwiftUI, MVVM, and lint discipline.
