https://github.com/apache/arrow-rs/blob/object_store_0.7.0/object_store/CHANGELOG.md looks like a good release, I'll probably take a look at upgrading this weekend if I can find the time

Any chance you could sneak this change in too? https://github.com/delta-io/delta-rs/compare/main...kvap:delta-rs:s3-rename-if-not-exists

is that commit in a pull request I'm not seeing?

Just on a fork right now, I don't think there is a PR

I actually just opened https://github.com/delta-io/delta-rs/pull/1592 to fix some issue with envioronment handling and move to the url parsing from object store. We dop have to wait until datafusion adopts the new object store version though ...
