I’m running the nightly from 3 days ago, looks to be the same based on code history. Working great, installed a bunch of plugins and all was well, including one that needed numpy.
Will update my other two PIs shortly.

Thanks for all the hard work!

After this, we will just have to convince as many people as possible that Python 2 is bad and they should be upgrading to Python 3... :smile:

From what I have seen, this must be quite a stable build. Have had to recommend people run nightlies for a couple of weeks with the newer Pi 4 revisions, or Pi4 8GB, and the vast majority say it has worked great for them. There are one or two issues with the 64 bit builds, but then that is probably the upstream image, not OctoPi. Maybe it will be worth mentioning this on the download page, that technically it is still in beta upstream?

:clap: @guysoft and all contributors.

Could not agree more. 0.18.0rc1 is stable 2 prints in but I have been using python3 for a month or maybe two. Python 3 did improve some issues so the time to jump on it is now. Using pi4 4gb and pi3b.

Very excited to see HLS support getting some love.

Interested in seeing how you make out with that. I think you have to use OctoPrint 1.5.0, but I think it's right around the corner for RC as well.

It is. Tuesday if nothing throws a wrench in my plans. Would be today if I didn't have a strict "no releases or release candidates after wednesday" policy (I've been burned before) and would be Monday if I didn't have an appointment there right in the middle that would interfere.

Hey, is there a way to upgrade an existing octopi installation?
Or do I need to reinstall a clean image?

@foosel, is there an option in octoprint to backup all settings and import them to a fresh installation?

There is an option under the settings called 'backup and restore'

You have to re-flash the SD card.

Im currently running Version 0.18.0, running on Raspberry Pi 4 Model B Rev 1.4 rc1 32-Bit
Stable so far, have found issues on 64-Bit version causing freezing & connection issues to usb driver as well as plugin crashes.

Switching to 32-Bit has been very stable and no issues to report so far.

I am running OctoPi 0.18RC1 (arm64) on an RaspberryPi (4GB) and can not report any issues. It works.

But i am wondering why the release of arm64 images have been stopt. Are theire any reasons?

You're running 0.18rc1, which is the latest image. The nightly builds are probably all the same, since there has not been any source changes since end of October. When there are updates, maybe they will be rebuilt.
