+
+[Full Changelog](https://github.com/delta-io/delta-kernel-rs/compare/v0.6.1...v0.7.0)
+
+### 🏗️ Breaking changes
+1. Read transforms are now communicated via expressions ([#607], [#612], [#613], [#614]) This includes:
+    - `ScanData` now includes a third tuple field: a row-indexed vector of transforms to apply to the `EngineData`.
+    - Adds a new `scan::state::transform_to_logical` function that encapsulates the boilerplate of applying the transform expression
+    - Removes `scan_action_iter` API and `logical_to_physical` API
+    - Removes `column_mapping_mode` from `GlobalScanState`
+    - ffi: exposes methods to get an expression evaluator and evaluate an expression from c
+    - read-table example: Removes `add_partition_columns` in arrow.c
+    - read-table example: adds an `apply_transform` function in arrow.c
+2. ffi: support field nullability in schema visitor ([#656])
+3. ffi: expose metadata in SchemaEngineVisitor ffi api ([#659])
+4. ffi: new `visit_schema` FFI now operates on a `Schema` instead of a `Snapshot` ([#683], [#709])
+5. Introduced feature flags (`arrow_54` and `arrow_53`) to select major arrow versions ([#654], [#708], [#717])
+
+### 🚀 Features / new APIs
+
+1. Read `partition_values` in `RemoveVisitor` and remove `break` in `RowVisitor` for `RemoveVisitor` ([#633])
+2. Add the in-commit timestamp field to CommitInfo ([#581])
+3. Support NOT and column expressions in eval_sql_where ([#653])
+4. Add check for schema read compatibility ([#554])
+5. Introduce `TableConfiguration` to jointly manage metadata, protocol, and table properties ([#644])
+6. Add visitor `SidecarVisitor` and `Sidecar` action struct  ([#673])
+7. Add in-commit timestamps table properties ([#558])
+8. Support writing to writer version 1 ([#693])
+9. ffi: new `logical_schema` FFI to get the logical schema of a snapshot ([#709])
+
+### 🐛 Bug Fixes
+
+1. Incomplete multi-part checkpoint handling when no hint is provided ([#641])
+2. Consistent PartialEq for Scalar ([#677])
+3. Cargo fmt does not handle mods defined in macros ([#676])
+4. Ensure properly nested null masks for parquet reads ([#692])
+5. Handle predicates on non-nullable columns without stats ([#700])
+
+### 📚 Documentation
+
+1. Update readme to reflect tracing feature is needed for read-table ([#619])
+2. Clarify `JsonHandler` semantics on EngineData ordering ([#635])
+
+### 🚜 Refactor
+
+1. Make [non] nullable struct fields easier to create ([#646])
+2. Make eval_sql_where available to DefaultPredicateEvaluator ([#627])
+
+### 🧪 Testing
+
+1. Port cdf tests from delta-spark to kernel ([#611])
+
+### ⚙️ Chores/CI
+
+1. Fix some typos ([#643])
+2. Release script publishing fixes ([#638])
