openHAB 3.4 has arrived!

Fully in line with the promised schedule, we have published openHAB 3.4 today!

Please take some time to read through our release notes on Github and also check the (very few) breaking changes before doing the upgrade.

Please also note our release announcement blog post if you want to share the news on social media.

You can get the 3.4 release from our download page or directly through your favorite Linux package manager.

Any discussions with regards to this release can be done in this new topic.

As always, I like to thank everyone that was involved in making this release possible. There are always hundreds of people involved and it is not possible to name them all and thank them individually, but please note that every contribution is highly valued and it is wonderful to have such a thriving community.

I wish you all much fun with the new release, smooth upgrades, creative new automation rules and hopefully a few days off from your work and having time for your families and of course for your favorite hobby!


We have just published a first patch release 3.4.1 with a few bug fixes.
Please see the release notes for the fixes that are included. There is no need to update your installation, if none of these fixes is relevant to you.


A new patch release 3.4.2 is now available - please find its release notes on GitHub.

We have just released yet another patch release for openHAB 3.4:
Please find the details of openHAB 3.4.3 in its release notes.
We specifically recommend all Netatmo users to update to this release, since the Netatmo binding will otherwise stop working after April 17 due to changes of the Netatmo cloud service.


The past weeks have shown again that local connectivity should always the preferred way for device integration - unfortunately, this is not always possible or supported by the vendors.
We have at least 3 bindings that stopped working due to API changes on the cloud services: Bosch Indigo, Windcentrale and Tesla. This is enough reason to ship another patch release for openHAB 3.4: Please see the release notes of openHAB 3.4.4 on GitHub. As you can see, it not only fixes these 3 bindings, but it also brings some additional improvements for a few other bindings.

If you are not using any of the concerned bindings, there is no need to update to this release. Everyone using any of these bindings is encouraged to upgrade to 3.4.4.


Even though openHAB 4 is now out, we are still taking care of our openHAB 3.4 users - we just created a patch release with a few updates to make openHAB 3.4 continue to run smoothly. A few cloud APIs had changed, which made adaptions to our bindings necessary. Please check out the release notes of openHAB 3.4.5 on GitHub!
We recommend the update to all 3.4 users (even if you do not use any of the listed bindings), since it also prevents an issue with newer JDK 11 builds.

Since the 3.4 downloads are not anymore prominently on our download page, you can easily find the binaries under “Assets” at the bottom of the GitHub release notes page.
