I am in the final phases of making the 59.2.0 release
59.2.0(July 2026) #9879Then I think we should open up main and start preparing the 60.0.0 release ASAP as we already have quite a few changes queued up
alamb commentedon Aug 3, 2026
FWIW i have made the 59.2.0 release candidate so from my perspective we can start merging PRs now that target 60 (and have breaking API changes)
I wonder if we should make an upgrade guide for arrow too?
etseidl commentedon Aug 3, 2026
Yay. I'll start breaking things right now 😄

just a callout that we'll have a new crate,
arrow-cmp, from this PR as part of this release:arrow-cmpcrate #10325alamb commentedon Aug 5, 2026

And I added a new checklist item to update the permissions after the first publishing:
ANd I see the instructions are updated: https://github.com/apache/arrow-rs/pull/10325/changes#r3721973865
Rich-T-kid commentedon Aug 10, 2026
would be nice to also get #10614 in, as it does introduce a breaking API change
alamb commentedon Aug 11, 2026
Added to the list
Rich-T-kid commentedon Aug 11, 2026
#10652 as well 😅 (not a breaking change) but new public method
alamb commentedon Aug 14, 2026
I tested out upgrading in datafusion here:
There are a few nice to have things that would make the upgrade eaiser:
Metadata::retainto filter entries in place #10683Metadata's innerArc(e.g.as_arc/into_arc) #10684arrow::utilrandversion, breaking downstreams on a different rand major #10685impl From<[(K, V); N]> for Metadataso array literals work withwith_metadata#10686That I added to the list above

@alamb how exactly does this work for bumping the version in datafusion? Im not sure what the process is but I could try making a PR for it.
alamb commentedon Sep 16, 2026
Hi @Rich-T-kid -- basically you just make a PR in datafusion. However, I have one already I have been working on
60.0.0andobject_store0.14.2datafusion#25335I often make one of those so I can run the datafusion tests on the arrow/parquet release candidate so we can find issues before merging
Rich-T-kid commentedon Sep 16, 2026
ah okay, will take a look 👍
