June 2026 — nrfconnect/sdk-nrf: Security hardening and reliability improvements through DTLS/TLS hostname verification consistency. Removed TLS-only guard to apply hostname verification for DTLS as well, and updated unit tests validating hostname handling in the socket configuration flow. The change was committed to the repository (commit 16b9fb9100174fa363feef216d6f1ea407f4ed76).

April 2026 delivered meaningful business and technical improvements across Asset-Tracker-Template and firmware projects. Key features upgrade memory and performance, strengthen deployment reliability, and improve telemetry and device tracking: - sdk-nrf upgrade with TF-M heap optimization to reduce memory pressure and boost performance. - Modem FOTA and TF-M settings optimization to align buffers and ensure static key slots, improving memory management. - Memfault tests updated to identify devices via UUID instead of IMEI, enhancing diagnostics and telemetry integrity. - Firmware CI/CD and deployment workflow enhancements, including post-flash device reset with pyocd to improve reliability of firmware deployments.
