Download OpenHAB 3.2.0

OpenHAB is home automation software with which components can be read and controlled. You can think of light switches, various sensors, LED lamps, security equipment and many other home automation hardware. It can be done through so-called binding talk via Z-Wave, Nest and Zigbee, or control products from Ikea Trådfri, Xiaomi Smart Home and Philips Hue. For more information, please refer to this page and for user experiences you can also visit our Forum, in the The Great OpenHAB topic. The developers have released OpenHAB 3.2 and the release notes for that version look like this:

openHAB 3.2 Release

Our winter release of openHAB 3.2 is out! This latest version contains many new add-ons, enhanced voice features, automation improvements and more! Another year is coming to its end and so it is time for us to bring you this openHAB release just in time for the festive season!

In the recent days and weeks the IT industry has been dealing with the fallout from vulnerabilities found in the log4j library, aka Log4Shell – prompting around the clock remediation efforts by developers and other IT professionals, especially those who operate Java based systems.

As openHAB is based on Java, we were impacted as well. To ensure we are protecting our users and community, we have addressed the major risks through the 3.0.4 and 3.1.1 patch releases that were published shortly after the fixed log4j 2.15 was out. Looking at the statistics of Maven Central that are provided by Sonatype, we have been ahead of many in the general industry, while at least 50% are still consuming vulnerable log4j versions < 2.15.

Since log4j 2.15 has been released, many security researchers have focused on testing this new version, and in consequence further (partially less critical) issues were found that led to the latest log4j versions 2.16 and 2.17 being released. We are happy to tell you that openHAB 3.2 already contains the (as of writing) very latest version 2.17, which should give our users a good reason to update their installations.

This dramatic log4j story has shed light on a larger issue we have in our industry: Open Source maintenance is often only done by engaged individuals in their spare time and their work is rarely recognized by the people that depend on such libraries. In the case of log4j, two passionate developers are taking care of the project in their free time, while nearly the entire Java industry depends on it. These people do a tremendous job and they hopefully get the recognition (and sponsors from the industry) they deserve.

Having said this, I would like to also make sure that our openHAB committers are recognized for their work. While I often do the announcements, I don’t contribute to the code base that much anymore – the major work is on the shoulders of many individuals that – most of the time silently – keep coding and contributing to our common project. I therefore like to thank every contributor, especially the ones of the 18 new addons that are included in the 3.2 release.
