+## [v0.12.0](https://github.com/delta-io/delta-kernel-rs/tree/v0.12.0/) (2025-06-04)
+
+[Full Changelog](https://github.com/delta-io/delta-kernel-rs/compare/v0.11.0...v0.12.0)
+
+### 🏗️ Breaking changes
+1. Remove `GlobalScanState`: instead use new `Scan` APIs directly (`logical_schema`, `physical_schema`, etc.) ([#947])
+2. table feature enums are now `internal_api` (not public, unless `internal-api` flag is set) ([#998])
+
+### 🚀 Features / new APIs
+
+1. Use compacted log files in log-replay ([#950])
+2. New `#[derive(IntoEngineData)]` proc macro ([#830])
+3. Add support for kernel default expression evaluation ([#979])
+4. **New: panic in debug builds if ListedLogFiles breaks invariants** ([#986])
+5. Create visitor for getting In-commit Timestamp ([#897])
+6. Binary searching utility function for timestamp to version conversion ([#896])
+7. Enable "TimestampWithoutTimezone" table feature and add protocol validation for it ([#988])
+8. add missing reader/writer features (variantType/clustered) ([#998])
+
+### 🐛 Bug Fixes
+
+1. Disable timestamp column's `maxValues` for data skipping ([#1003])
+
+### 🚜 Refactor
+
+1. Make KernelPredicateEvaluator trait dyn-compatible ([#994])
