title: "Kernel Release Cycle 20"


{: .image-responsive .pull-right}

[Dexter Industries] made some major breaking changes to their BrickPi3 firmware,

so this release is all about the BrickPi3 (again). Major shout-out to

@sanjayseshan for spending a significant portion of his spring break helping to

get the drivers updated for the BrickPi3 firmware v1.4.x. We also now support

stacking up to 4 BrickPi3s on a single Raspberry Pi.

There are also some kernel modules enabled for using GSM modems with the EV3.

And finally, a corner case involving stopping motors before a position setpoint

is reached was fixed.
