+# Releases
+
+The binary.hex files for the most recent releases of MicroData are available ![here](https://github.com/KierPalin/MicroData/releases).<br>
+There is currently a trade-off between microdata-v1.5.0 and microdata-no-jacdac-mode-v1.5.0. <br>
+* microdata-v1.5.0 has support for all sensors. When the Arcade Shield is not connected the microbit defaults to Commander mode (it listens to logging commands over the radio).
+* microdata-no-jacdac-mode-v1.5.0 does not support the Jacdac. When the Arcade Shield is not connected the microbit defaults to a mode that allows you to log data without an Arcade Shield (or enter Commander mode).
