rust-v0.32.2

This release adds support for the VARIANT data type.

This release fixes several regressions, including issues with MERGE operations, overwriting tables with partition changes, and schema mode with mixed-case columns. It also enables passing non-string datatypes in custom commit metadata and updates the minimum PyArrow version to 21.0.0 for preliminary variant type support.

This release improves the new Datafusion TableProvider and log parsing performance, alongside numerous bug fixes addressing issues like incorrect row counts for deletes, merge failures, and S3/Azure storage inconsistencies. A new feature allows adding post-commit hook properties to DeltaTable.restore operations.

python-v1.5.0: faster writes, log compaction, spil config in MERGE

This release introduces faster Delta table writes through parallel partition writers and adds log compaction for improved performance. The `get_add_actions` method now returns an Arrow Table instead of an Arrow RecordBatch, which is a breaking change.

This release provides a fix for a Rust-related issue, specifically backporting a previous pull request. Databricks users will see improved stability due to this underlying fix.

This release introduces a session-first DataFusion integration and exposes Delta Lake Vacuum (DV) metadata as Arrow streams. It also fixes issues with schema merge appends for generated columns and improves parquet predicate pushdown.
