 - **EXPERIMENTAL** Evaluation of `EXCLUDE` in the `EvaluatingCompiler`
   - This is currently marked as experimental until the RFC is approved https://github.com/partiql/partiql-lang/issues/27
   - This will be added to the `PhysicalPlanCompiler` in an upcoming release
+- **EXPERIMENTAL**: Adds support for EXCLUDE in the default SqlDialect.
 
 ### Changed
 - StaticTypeInferencer and PlanTyper will not raise an error when an expression is inferred to `NULL` or `unionOf(NULL, MISSING)`. In these cases the StaticTypeInferencer and PlanTyper will still raise the Problem Code `ExpressionAlwaysReturnsNullOrMissing` but the severity of the problem has been changed to warning. In the case an expression always returns `MISSING`, problem code `ExpressionAlwaysReturnsMissing` will be raised, which will have problem severity of error.

 ### Fixed
 - Fixes the CLI hanging on invalid queries. See issue #1230.
+- Fixes Timestamp Type parsing issue. Previously Timestamp Type would get parsed to a Time type.
 
 ### Removed
 - **Breaking** Removed IR factory in favor of static top-level functions. Change `Ast.foo()`
