Jul 1, 2025July 2025 monthly summary for espressif/esp-matter: Delivered two key outcomes with clear business value. Implemented Over-The-Air (OTA) update support for the Thread Border Router example, updating build/config to enable OTA, and adding related sdkconfig.defaults and host build steps to streamline deployment. Published RAM optimization guidance documentation detailing configuration options to reduce memory footprint and improve performance (dynamic endpoint counts, newlib nano formatting, BLE configurations). These initiatives enhance deployment reliability, performance, and developer efficiency across ESP-Matter deployments.
