[Media] Ariel OS v0.4.0 released!

I'm very happy to announce we've just released Ariel OS v0.4.0!

Ariel OS is an embedded library OS for microcontrollers.

Ariel OS takes Embassy, adds a preemptive scheduler and tons of integration and curation, and binds everything together into an easy-to-get-started package.

This release has a bunch of useful tooling upgrades, enables BLE on esp32, and many other improvements!
