    ; Latest stable version
    [env:latest_stable]
    platform = linux_arm
    board = ...

    ; Custom stable version
    [env:custom_stable]
    platform = linux_arm@x.y.z
    board = ...

### Upstream

    [env:upstream_develop]
    platform = https://github.com/platformio/platform-linux_arm.git
