To quote them:

We are still in a fast development cycle, so the versioning is to keep track of the progress/iteration of the project. When a stable release is reached (2?), then any breaking change would require more proper major version changes

I was going to say you are wrong about semver but you are correct that it should simply not be version 1 yet.

To quote semver.org: “Major version zero (0.y.z) is for initial development. Anything MAY change at any time. The public API SHOULD NOT be considered stable.”

If they had just done that, their disclaimer would be implied. Once it is 1.0, breaking changes require a major version change. That seems like reasonable policy to me.

That said, I upgraded without issue.

It's not that kind of breaking change. It's a change that won't affect most people. Only those who chose to use a custom location for their media location and chose to set that to a relative path instead of an absolute one which caused the application to have trouble resolving the paths. The change eliminates a bug by preventing people from doing something that was not intended to be supported. So it's not a "breaking" change necessarily in the sense that they are changing documented functionality. They are eliminating a way that people can misconfigure the application which may in some cases cause the application to break if someone successfully configured the application in this unintended way.

Immich isn’t a library (the main use case for semver is dependencies that will be pulled into other projects) and as far as I know they don’t state that they use semver.

Hmm I'll have to double check that. My server has 4 or 5 hard drives, I start to lose track of what's where 😅

I don't have issues with Photoprism though.

Sure, but it's better than the alternative

It doesn't automatically put them into albums that way it just dumps them all. In the main collection. I found a JavaScript that will use the API to create albums from the folder structure and added some features to it. So if you do stand it up and want that just ping me. I need to throw it on git anyway just need to find the original author to credit.

My experience is that Immich is more stable than Nextcloud, despite being 'pre-release'

Nextcloud had bugs that corrupted data several times when I was using it, switched away from it awhile ago because of that. NC also feels slow even with all the tuning they recommend.

I haven't had any stability issues with immich and I've been running it for over a year. Nextcloud has always been pretty slow for me and I've not had that issue with immich.

Gah, Nextcloud is missing all the features and is frankly unusable (mobile apps are slow, can't make or view albums, and can't "open with" links on Android at least). My family uses it and my biggest project right now is importing all our stuff to Immich when I finally get the NixOS server ready to replace Ubuntu.

It's not giving you proactive notifications for it, but yes, that's the one. It's just available on top of your timeline just like in Google photos.
