For 2026-03, expressvpn/lightway delivered automated dependency maintenance and CI updates to strengthen stability and release velocity. A weekly cadence for updating Cargo and Nix Flakes was established, and the flake.lock lockfile was updated to reflect the latest inputs across flake-parts, nixpkgs-lib, nixpkgs, and rust-overlay. This work reduces drift, mitigates maintenance backlog, and improves reproducible builds in CI.

January 2026: Focused on stabilizing Darwin ARM64 address handling in the wolfSSL integration (wolfssl-rs). A backported fix to wolfSSL 5.8.2 addressed incorrect address calculation on Apple platforms, improving correctness and compatibility. This work reduced cross-platform risk and supported smoother builds and deployments for Darwin environments.

Monthly Summary for December 2025 (expressvpn/lightway): Delivered two main features and one bug fix, with focused improvements to cryptography, IPv6 interoperability, and observability. This month emphasized business value through security enhancements, broader connectivity options, and reliable diagnostics.

In November 2025, delivered a key security enhancement in expressvpn/wolfssl-rs by adding Post-Quantum Cryptography support: CurveGroup x25519-ML-KEM-768 hybrid method. Implemented in commit b4cd801cf55dc064778bafed4136a709442202f0. This progress strengthens quantum-resistant key exchange, supports future PQC migrations, and broadens compatibility for PQC-capable deployments. No major bugs fixed this month in the scope of this repo. Impact: improved security posture for users in sensitive environments and readiness for standards-aligned PQC deployment. Technologies: Rust, curve groups configuration, ML-KEM integration, X25519, secure key exchange design.

Monthly summary for 2025-10 (expressvpn/lightway): Focused on stabilizing cross-architecture builds and CI reliability by addressing ARM crypto support and simplifying test gating. Key improvements delivered in the lightway repository resulted in broader platform compatibility, faster feedback, and reduced maintenance burden. Business impact includes enabled ARM crypto extensions on aarch64-linux and streamlined CI workflows.

September 2025 – expressvpn/lightway: Focused on improving stability and cross-platform build reliability to reduce flaky tests and accelerate releases. Highlights include gating tests that rely on debug_assert! to non-debug builds, centralizing cross-compilation configuration in Earthly to address native build issues and platform-specific failures, and reorganizing the cargo/Earthly build context by moving .cargo inside Earthly and refactoring Earthly targets for reproducible builds. These changes improve CI determinism, developer feedback loops, and overall release cadence across supported platforms.
