New Release Organisation

We have decided to change our current firmware versioning scheme to a new one that reflects a continuous delivery of software. We have been successfully using agile development (SCRUM) in the past 2 years which results in higher quality and faster delivery of our software. For such a development method our old way of releasing firmware wasn't appropriate anymore. The new versioning scheme will have the last 2 digits of the current year and an incrementing 2 digit number in it:


As an example our first firmware in 2016 is the 16.01 (equals to the 3.1 firmware), the next one will be 16.02. The first one in 2017 will be 17.01. This scheme is comparable to the Ubuntu versioning scheme.

Old Release Organisation

There are 2 kinds of firmware verions, Releases and Patches. The Releases are divided in Major and Minor releases. Minor Releases with the same Major will receive only security fixes and general bugfixes. Newer Major Releases might contain newer features. Between 2 Minor Releases there might be multiple Patch-Releases.

The Firmware Name for a Release is then


The Firmware Name for a Patch is then


This page will contain information about the current release and about the changes between each release, where the newest release is the most recent entry.

We try to release a minor release every quarter of a year and a major between 1-2 years.

Most hardware related Features require an FPGA Update to at least Version 6. Please Note the Howto update the FPGA on this matter.

Please have a look at our growing Documentation V2.

For berofix API users please note the API Changelog.

NOTE: Please make sure, that you are at a Firmware >= 1.12 BEFORE updating to 2.X 
            ALSO: make sure that you did a "red Activate" with this new Firmware (e.g. 1.13rc10)
NOTE 2: It might happen that after the upgrade your current configuration is lost. We advise you to backup
