Update 2026.02.3 dropping most PI support?

Installation Home Assistant OS
1

Did I read it correct under breaking changes, #6607 that HAOS no longer will run on older PI’s well if you call the PI4 obsolete, that is?

this was written in the topic:

Proposed change [Preformatted text](https://github.com/home-assistant/supervisor/releases/tag/2026.03.0)

Drop support for deprecated CPU architectures (armhf, armv7, i386) and their associated machine types (raspberrypi, raspberrypi2, raspberrypi3, raspberrypi4, qemuarm, qemux86, odroid-xu, tinker) from Supervisor. These machines are no longer supported by HAOS.

I worry, and await responses from users here is it true that my PI4 will no longer be supported? I am not wanting to ruin a fine working installation of HA, in this time of memory idiocracy where a new machine will be 200% more expensive then a few months ago.
I feel no need for proxmox or a bare metal or Docker installation.

Please how should I read this info, and should I install this pending update on my PI4?

Hi JJ,

I believe this is for the 32-bit architectures, so if you’re on HAOS check the hardware info under Settings → System → Hardware , if it says something like Raspberry Pi 4 64-bit you should be fine. (Settings → About, assuming it says Installation Method Home assistant OS)

If it is the 32-bit version of Home assistant OS, to continue upgrading you’ll need to backup your home assistant and install the latest Home assistant OS which should be 64-bit (e.g. Raspberry Pi - Home Assistant) and restore from backup

I updated my pi4, works fine. 64 bit

the 32 bit version simply won’t show you an update FYI.

    "raspberrypi": "2025.11.3",
    "raspberrypi2": "2025.11.3",
    "raspberrypi3": "2025.11.3",
    "raspberrypi3-64": "2026.3.1",
    "raspberrypi4": "2025.11.3",
    "raspberrypi4-64": "2026.3.1",
    "raspberrypi5-64": "2026.3.1",

That file regulates whether or not you’ll get a notification for an update. I.e. it’s safe to update.

Only small mem (<1 GB) and 32 bit.

64 bit pi (pi4 and better) are fine. Even though the price / performance curve is no longer in thier favor v. x64.

Small. Dev team they have to make hard decisions. This keeps thier work down and supports the most future platforms at the moment. If they don’t depricate things sometimes… they become Windows…

Thank you all for the information, my Pi4 is with more memory and runs 64Bit.

Note, small mem 64-bit Pis (512K PiZero2W, 1GB Pi3/Pi4) can still be supported with latest HA docker releases on streamlined AlpineLinux-based system enabling zram compression.
A seamless automated install method is available here (doc within script comments) as an option to AlpineLinux Headless Bootsrapping tool (ALHB).
