v0.7.0

Python

• Read Delta tables as PyArrow batches or query them with SQL. Includes column
  selection, filters, snapshot refresh, and streaming results.
  Quickstart and
  API reference.
• Python wheels include the native delta-arrow-reader command and support
  CPython 3.10+ on Linux x86_64, Windows x86_64, and macOS arm64.
  Platform requirements.

Command line

• Use dar inspect to view a table's schema and version, and dar scan to stream
  selected rows and columns as Arrow IPC. Supports filters and configurable
  resource limits. CLI quickstart.
• Run dar from standalone Linux amd64 or arm64 archives or container images.
  Installation.

Selective reads

• Filtered S3 queries can now download selected values within Parquet pages.
  Automatic selection is enabled by default and uses the file layout and measured
  network conditions to choose when smaller reads are likely to be faster.
• Supports fixed-width numeric and decimal values, plus strings and binary
  values in supported file encodings.
  Supported layouts and benchmarks.

Upgrading from 0.6

• Opening supported S3 tables now includes network sampling with a five-second
  budget, separate from metadata loading. Use WarmupMode::None or
  WarmupMode::QueryPlanning to skip sampling and partial-page reads.
  Configuration.
• WarmupMode includes a Network variant with configuration and no longer
  supports integer casts such as mode as u8. Code that stores modes as numbers
  must use an explicit mapping.

All changes since 0.6.2.

CLI v0.7.0

The CLI binaries and both container platforms passed download verification.
