pio-upgrade

pio upgrade [options]

pio upgrade checks for and upgrades the PlatformIO Core CLI tool itself to the latest release. By default it installs the latest stable version. Use --dev to install the development version for testing new features before they are officially released.Unlike pio update, which updates project platform packages and libraries, pio upgrade targets the underlying PlatformIO Core installation.

--dev

Upgrade to the latest development version instead of stable. Provides access to new features before official release but may be less stable.

Requires an internet connection to download the update. May require elevated permissions depending on the installation method (e.g., system-wide pip install). After upgrading, restart any running PlatformIO processes or IDE integrations.
