[Full Changelog](https://github.com/delta-io/delta-kernel-rs/compare/v0.7.0...v0.8.0)

### 🏗️ Breaking changes

1. ffi: `get_partition_column_count` and `get_partition_columns` now take a `Snapshot` instead of a
`Scan` ([#697])
2. ffi: expression visitor callback `visit_literal_decimal` now takes `i64` for the upper half of a 128-bit int value ([#724])
3. - `DefaultJsonHandler::with_readahead()` renamed to `DefaultJsonHandler::with_buffer_size()` ([#711])
4. DefaultJsonHandler's defaults changed:
- default buffer size: 10 => 1000 requests/files
- default batch size: 1024 => 1000 rows
5. Bump MSRV to rustc 1.81 ([#725])

### 🐛 Bug Fixes

1. Pin `chrono` version to fix arrow compilation failure ([#719])

### ⚡ Performance

1. Replace default engine JSON reader's `FileStream` with concurrent futures ([#711])
