This is openHABian, the image to combine RaspiOS and openHAB.
Support for Java 21 has been added for openHAB 5. Please note that openHAB 5 requires Java 21 but there are no official JVM 21 builds in 32 bit so if your OS is still 32 bit you eventually may need to reinstall your system. Use getconf LONG_BIT to find out your OS' bitness.
So if your hardware enables you to go with 64 bit - which essentially means you should have 2 GB of RAM or more -, use the 64bit image.
Note: Please read the docs on 32/64bit for which one to choose so you can have the best experience with your hardware.
For people to be stuck on 32 bit due to 32bit hardware, we have added an experimental 32 bit JVM 21.
This seems to be working, but ATTENTION: essentially it is untested and NOT supported.
Also, we might get forced to remove it at any future time without providing a working replacement.
This Java package is meant to ease transition to OH 5 but NOT a permanent solution so if you're affected and cannot go 64 right away don't sit back and relax but continue planning your personal transition.
If you come across any issues or have any comments you'd like to share please discuss them in this thread.
When you select openHABian in Raspberry Pi imager, it will offer you the latest stable release (i.e. this one).
Or download the image here and use Raspi imager or Etcher to manually flash it to a micro SD card (preferrably use an 'Endurance' labelled card).
