Arri Firmware V3.0

ARRI has just completed extensive testing on the new ALEXA Firmware 3.0, due to be released in early February. It includes so many new features that ARRI has decided to release a Beta version to allALEXA owners a few weeks in advance of the official release date. This will allow ARRI to receive valuable feedback on the performance of the 3.0 upgrade from its growing ALEXA install base prior to the firmware’s official release.

Here are the key features of the ALEXA 3.0 firmware.
