Version 1.5 of the nRF Connect SDK has been release: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.5.0/nrf/index.html
This time I worked closely on one one of the "Highlights" featured in the release notes: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.5.0/nrf/releases/release-notes-1.5.0.html
Can you guess which one?
