4.4.0

We're happy to announce updated support for the new Mbed OS 6 with stable and mature APIs, Cloud services support, Enhancements to the Bare Metal Profile. For boards which don't support the latest Mbed release, Mbed OS 5 remains as the default choice. The list of deprecated boards in Mbed OS 6 can be found here.

Update support for mbed framework:

• Update Mbed OS6 to v6.2.0 (release notes)
• Update Mbed OS5 to v5.15.4 (release notes)

Please note

Due to breaking changes in Mbed OS 6 existing Mbed projects might not be compatible with the latest API changes. In order to keep legacy projects built on top of Mbed OS 5 compilable, a list of deprecated boards is used to dynamically select the proper version of Mbed OS (OS5 or OS6). To force the platform to use Mbed OS 5, specify the Mbed package version using platform_packages option in platformio.ini file:

[env:nrf52840_dk]
platform = nordicnrf52
framework = mbed
board = nrf52840_dk
platform_packages =
    framework-mbed @ ~6.51504.0

More information on project configuration for Mbed framework can be found here.
