Highlights

In this section, we are going to highlight the most important changes and features introduced in PlatformIO Core 6.2. Please visit PlatformIO Core 6.2 Release Notes for more detailed information.

Python 3.9+ is now required

PlatformIO Core 6.2.0 drops support for Python 3.6, 3.7, and 3.8. Python 3.9 or newer is now required to run PlatformIO Core.

If you are using an older Python version, upgrade your Python installation before updating PlatformIO Core.

Streamlined port configuration

The pio run command now provides a new -p, --port option. It allows you to specify the device port once and have it applied to both upload_port and monitor_port, making common build, upload, and monitoring workflows simpler.

For example:

pio run -p /dev/ttyUSB0

This is particularly useful when the same serial port is used for both uploading firmware and monitoring the device.

More control over environment checks

PlatformIO Core 6.2.0 introduces additional configuration options for users working in customized development environments.

You can now disable the 99-platformio-udev.rules check when system-level udev configuration is not required. A new PLATFORMIO_DISABLE_UPGRADE_CHECK environment variable also allows upgrade availability checks to be disabled when needed.

Updated SCons build engine

The build engine has been upgraded to SCons 4.11.1, bringing improvements in build performance, reliability, and compatibility with other tools and systems.

Improved package handling

PlatformIO Core now supports longer dependency version specifications, including long package URLs in project manifests.

On Windows, package extraction now detects path-length-related FileNotFoundError conditions and reports a descriptive error with instructions for enabling Windows long paths.

More accurate unit testing output

Unit Testing output has been improved when environments or test suites are filtered with -e or -f. Skipped environments and test suites are now omitted from the summary, making the reported results easier to understand.

This release also fixes several issues affecting unit testing on Windows, test status reporting, and test framework dependencies.

Security improvement

PlatformIO Core 6.2.0 includes an important security fix for ZIP archive extraction.

Previously, ZIP archives containing relative path traversal entries such as ../ could potentially modify permissions or timestamps of files outside the intended destination directory. The package extraction process has been fixed to prevent this behavior.

We recommend that all users update to PlatformIO Core 6.2.0.

Reliability and compatibility improvements

This release addresses a broad range of issues across the PlatformIO Core ecosystem, including:

  • Fixed an infinite retry loop when a cached package mirror redirect repeatedly failed.
  • Fixed library integrity metadata not being invalidated after invalid version requirements were corrected.
  • Fixed pio device monitor failures when using a relative path with -d, --project-dir.
  • Improved compatibility with pipx- and uvx-managed environments by ensuring the required pip dependency is available for Python-based tool packages.
  • Fixed compilation failures caused by debug flags with level specifications, such as -g2, being incorrectly passed to standalone assemblers for .s files.
  • Fixed floating-point precision issues in duration formatting that could result in incorrect millisecond values.
  • Fixed pio device monitor handling of redirected or non-TTY stdin, replacing an unhandled termios traceback with a clear user-facing error.
  • Fixed static analysis reports generated incorrectly when projects were analyzed in verbose mode.
  • Fixed unintended removal of test framework libraries from project dependencies when building outside testing mode.
  • Fixed relative header paths supplied through -include build flags not being converted to absolute paths in c_cpp_properties.json, which could cause IntelliSense errors.

PVS-Studio support removed

Support for static code analysis with PVS-Studio has been removed following its deprecation by the vendor.

Upgrade

  • PlatformIO IDE: Left Sidebar > PlatformIO (icon) > Quick Access > Upgrade PlatformIO Core
  • Terminal: Please run pio upgrade command in terminal.

Major Milestones

6 Million Unique Installations

From the first installation to now, our PlatformIO IDE for VSCode extension has grown faster than we ever imagined. Today, it has been installed over 6 million times! Each installation represents someone choosing to make their work easier, smarter, or more fun. Seeing this many people benefit from our work is truly inspiring.

Our success has also inspired many silicon vendors to introduce their own solutions and tools for VSCode. Even so, PlatformIO remains the most popular VS Code extension for embedded development and we’re proud to hold this position thanks to the trust of our community.

PlatformIO Yearly Active Users (2014-2025)

We’re happy to announce updated support for the latest release of ESP-IDF v5.4.1 - 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 v5.4.1:

  • Added config to enable/disable BLE channel assessment and ping procedure on ESP32
  • Optimization of RX calibration for Wi-Fi in high-interference environments
  • Added MALLOC_CAP_SIMD flag to allocate memory that is suitable for SIMD instructions

More information on project configuration for ESP-IDF can be found here.

This month we received a lot of helpful feedback from our community, which let us identify the most important parts of our OSS ecosystem that required our attention, so there are plenty of updates pushed in this month that we hope you will like.

PlatformIO Open Source March Updates

During March, we released a bugfix release for PlatformIO Core, added support for the latest Zephyr framework, rolled out updates for ST STM32 and Renesas RA development platforms, fixed a lot of issues. Some of the key highlights include:

PlatformIO Core 6.1.18

PlatformIO Core is the heart of the whole PlatformIO ecosystem and we are excited to announce the next v6.1.18 release with lots of great improvements and bugfixes:

  • Introduced the PLATFORMIO_RUN_JOBS environment variable, allowing manual override of the number of parallel build jobs (issue #5077)
  • Added support for tar.xz tarball dependencies (pull #4974)
  • Ensured that dependencies of private libraries are no longer unnecessarily re-installed, optimizing dependency management and reducing redundant operations (issue #4987)
  • Resolved an issue where the compiledb target failed to properly escape compiler executable paths containing spaces (issue #4998)
  • Resolved an issue with incorrect path resolution when linking static libraries via the build_flags option (issue #5004)
  • Resolved an issue where the --project-dir flag did not function correctly with the pio check and pio debug commands (issue #5029)
  • Resolved an issue where the LDF occasionally excluded bundled platform libraries from the dependency graph (pull #4941)
  • Resolved a regression issue that prevented PIO Home from opening external links (issue #5084)

See Release Notes for more detailed information and use pio upgrade command to update to the latest version.

Zephyr RTOS v4.1

We’re happy to announce updated support for the latest release v4.1 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 v4.1.0:

  • Multiple performance improvements of core Zephyr kernel functions
  • New USB MIDI 2.0 device driver, allowing Zephyr devices to communicate with MIDI controllers and instruments over USB
