rust-v0.28.0 (2025-08-27)

Full Changelog

⚠️ There is a known performance regression when opening very wide tables (50+ columns) that have hundreds of thousands of transactions. The fix is pending a new delta-kernel-rs release.

Implemented enhancements:

• Python: Automatically convert Pandas null types to valid Delta Lake types in write_deltalake() #3691
• Update HDFS object store to 0.15 #3680
• create a v2 uuid checkpoint regression test #3666
• Feature: update python table vacuum to add keep_versions parameter #3634
• TypeError in DeltaTable.to_pyarrow_dataset when using non-string partition filter values (e.g., int) #3597
• Make "cloud" feature optional #3589
• convert_to_deltalake cannot convert parquet dataset if it has millisecond-precision timestamps #3535
• Musl wheels #3399

Fixed bugs:

• Automatically register the AWS, Azure, GCS, HDFS, LakeFS, and Unity storage handlers when the corresponding feature is enabled so DeltaOps::try_from_uri no longer errors with unknown schemes such as gs://.
• Significant performance regression when opening S3 table on next branch #3667
• Concurrent overwrite doesn't fail conflict checking #3622
• source distributions missing in v1.1.1 #3621
• Missing linux distro for v1.1.1 #3620
• azurite tets failing in main #3612
• Generic S3 Error on _last_checkpoint on ARM64 AWS Lambda with write_deltalake #3602
• write_deltalake merge with list and large_list #3595
• Python DeltaTable does not support writes in multiple threads (again?) #3594
• Checkpoint creation fails on Azure in >=1.0.0 with "Azure does not support suffix range requests" #3593
• Partition value strings containing reserved ASCII and non-ASCII are double-encoded. #3577
• Deltalake version 1.0.2 errors with Azure Storage after appending many times #3567
• Python deltalake 1.0.2 is not compatible with polars.Array #3566
• Checkpoint schema breaking change between 0.25.5 and 1.0.2 #3527

Closed issues:

• Array/list not encoded with partition filters #3648

Merged pull requests:

• fix: reintroduce the 100 commit checkpoint interval #3708 (rtyler)
• fix: enabling correctly pulling partition values out of column mapped tables #3706 (rtyler)
• fix(format): fix formatting in Python for conversion file #3705 (fvaleye)

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
