@paleolimbot you seemed to be the one that pinned that version. Is there something else I should check?

[paleolimbot]

Nope...thanks! I'll remove the corresponding version pin in arrow-rs and arrow-nanoarrow as well 🙂

Thank you @raulcd

I double checked and indeed the CI test is green and rust is building successfully

I filed a ticket and PR for this issue in arrow-rs:

• Archery integration CI test is failing on main: error: package half v2.5.0 cannot be built because it requires rustc 1.81 or newer, while the currently active rustc version is 1.77.2 arrow-rs#7291
• Fix archery integration test arrow-rs#7292

Can we use this instead of #45801? I think that no pin is better.

yes I agree this PR is better. I closed #45801. Thank you @kou
