  "textContent": "Espressif Systems released the ESP-IDF v6.0 framework a few days ago with stable support for ESP32-C5 and ESP32-C61 SoCs, as well as preview support for ESP32-H21 and ESP32-H4 low-power wireless microcontrollers. The framework also implements a new ESP-IDF Installation Manager (EIM) to make the ESP-IDF installation easier, relies on the low-footprint Picolibc C library, adds security and tooling updates, as well as a few Wi-Fi enhancements, and the ability to update the bootloader over the air. Here are some of the ESP-IDF v6.0 highlights: ESP-IDF Installation Manager – Unified cross-platform tool to simplify the setup process for ESP-IDF and compatible IDEs. It’s available as a graphical interface or a CLI for automation and CI/CD pipelines. You can check the installation instructions for your OS. Picolibc replaces Newlib for a smaller memory footprint and better performance on resource-constrained devices. Check the Newlib vs Picolibc comparison for details.
