Comet 0.15.0 Release

[andygrove]

What is the problem the feature request solves?

I would like to start planning the 0.15.0 release. Let's use this issue to track important issues or PRs that we want to include in the release.

Describe the potential solution

Issues/PRs that we want to wait for before releasing 0.15.0:

• feat: enable native Iceberg reader by default #3819

Additional context

Not necessarily a blocker, just an FYI: iceberg-rust 0.9.1 might release soon if we want a crate instead of a pinned commit: apache/iceberg-rust#2303

I believe OpenDAL is planning a release this week as well, since I think we're pinned to a commit there as well.

Neither are necessary to wait for, I don't think. We could bump to the crate releases in a 0.15.1.
