ReadTheDocs failed to build the doc set. I put that file only back to 3.12.

You should add breaking change to release https://github.com/jertel/elastalert2/releases/tag/2.21.0 because you dropped version 3.12.

btw. IMO this drop was done too fast. You should consider alpine linux releases because this is very popular system.

@Karql Thanks for bringing this up. I agree, the removal of 3.12 support should have been mentioned as a breaking change. It was properly marked as a breaking change in the previous release when 3.9-3.11 was dropped.

@nsano-rururu Was there a specific reason you removed support for 3.12? If not we can add that support back for a few more months.

@jertel

There's no particular reason.
You don't need to ask my consent for how to proceed from now on.
I haven't used elastalert2 for quite some time now.

The elastalert2-server maintained by Karql uses a node docker image. Because it is based on alpine, it will take some time to get the latest python support.

The background should be explained properly. It is an unofficial tool. elastalert2-server is

There are many use cases for this tool.
For example, someone might run it directly on their system. There are systems that are more security-focused, where new application versions are added to the repository more slowly.

I see no reason to drop support for older Python versions.
None of the dependencies in use require this.
I also don’t see any specific features being used that are only available in newer Python versions.

Additionally, it's worth mentioning that version 3.12 will be supported for another 4 years.

Like I've said - In my opinion, dropping support for older versions just two days after the release of a new one is definitely too fast.
