PlatformIO Core 6.1.16
PlatformIO Core is the heart of the whole PlatformIO ecosystem and we are excited to announce the next v6.1.16 release with lots of great improvements and bugfixes:
- Added support for Python 3.13
- Introduced the PLATFORMIO_SYSTEM_TYPE environment variable, enabling manual override of the detected system type for greater flexibility and control in custom build environments
- Enhanced internet connection checks by falling back to HTTPS protocol when HTTP (port 80) fails (issue #4980)
- Upgraded the build engine to the latest version of SCons (4.8.1) to improve build performance, reliability, and compatibility with other tools and systems (release notes)
- Upgraded the Doctest testing framework to version 2.4.11, the GoogleTest to version 1.15.2, and the Unity to version 2.6.0, incorporating the latest features and improvements for enhanced testing capabilities
- Corrected an issue where the incorrect public class was imported for the
DoctestTestRunner(issue #4949)

Zephyr RTOS v3.7
We’re happy to announce updated support for the latest release v3.7.0 of Zephyr Project - a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource-constrained devices, and built with safety and security in mind.
Major enhancements in v3.7.0:
- Picolibc is now the default C standard library
- Added new modem subsystem
- Added support for linkable loadable extensions (llext)
- Added new hardware spinlock driver API

ESP-IDF v5.3.1
We’re happy to announce updated support for the latest release of ESP-IDF v5.3.1 - the official development framework for the ESP32, ESP32-S and ESP32-C Series SoCs. It provides a self-sufficient SDK for any generic application development on these platforms, using programming languages such as C and C++. ESP-IDF currently powers millions of devices in the field, and enables building a variety of network-connected products, ranging from simple light bulbs and toys to big appliances and industrial devices.
Major enhancements in v5.3.1:
- Added support for BLE 5.0 instances in related events
- Added support for ETM events as a wake-up source
- Added support for broadcast TWT
