+## [0.9.3] - 2023-04-12
+
+### Added
+- Added numeric builtins ABS, SQRT, EXP, LN, POW, MOD.
+- Added standard SQL built-in functions POSITION, OVERLAY, LENGTH, BIT_LENGTH, OCTET_LENGTH, CARDINALITY,
+  an additional builtin TEXT_REPLACE, and standard SQL aggregations on booleans EVERY, ANY, SOME.
+- **Breaking** Added coercion of SQL-style subquery to a single value, as defined in SQL for
+  subqueries occurring in a single-value context and outlined in Chapter 9 of the PartiQL specification.
+  This is backward incompatible with the prior behavior (which left the computed collection as is),
+  but brings it in conformance with the specification.
+- Added `partiql-plan` package which contains experimental PartiQL Plan data structures.
+- Initializes SPI Framework under `partiql-spi`.
+- Models experimental `Schema` with constraints.
+  With this change, we're introducing `Tuple` and `Collection` constraints to be able to model the shape of data as
+  constraints.
+- Introduces the PartiQLSchemaInferencer and PlannerSession
+  - The PlannerSession describes the current session and is used by the PartiQLSchemaInferencer.
+  - The PartiQLSchemaInferencer provides a function, `infer`, to aid in inferring the output `StaticType` of a
+    PartiQL Query. See the KDoc for more information and examples.
+
+### Changed
+- Deprecates the project level opt-in annotation `PartiQLExperimental` and split it into feature level. `ExperimentalPartiQLCompilerPipeline` and `ExperimentalWindowFunctions`.
+- **Breaking**: Moves StaticType to `partiql-types`.
+  - All references to static types need to modify their imports accordingly. For example,
+    `org.partiql.lang.types.IntType` is now `org.partiql.types.IntType`.
+  - Please modify existing dependencies accordingly. You may need to add dependency `org.partiql:partiql-types:0.10.0`.
+  - Also, several methods within StaticType have been moved to a utility class within `partiql-lang-kotln`. See the below list:
+    1. `org.partiql.lang.types.StaticType.fromExprValueType` -> `org.partiql.lang.types.StaticTypeUtils.staticTypeFromExprValueType`
+    2. `org.partiql.lang.types.StaticType.fromExprValue` -> `org.partiql.lang.types.StaticTypeUtils.staticTypeFromExprValue`
+    3. `org.partiql.lang.types.StaticType.isInstance` -> `org.partiql.lang.types.StaticTypeUtils.isInstance`
+    4. `org.partiql.lang.types.StaticType.isComparableTo` -> `org.partiql.lang.types.StaticTypeUtils.areStaticTypesComparable`
+    5. `org.partiql.lang.types.StaticType.isSubTypeOf` -> `org.partiql.lang.types.StaticTypeUtils.isSubTypeOf`
+    5. `org.partiql.lang.types.StaticType.typeDomain` -> `org.partiql.lang.types.StaticTypeUtils.getTypeDomain`
+    6. `org.partiql.lang.types.SingleType.getRuntimeType` -> `org.partiql.lang.types.StaticTypeUtils.getRuntimeType`
+    7. `org.partiql.lang.types.StringType.StringLengthConstraint.matches` -> `org.partiql.lang.types.StaticTypeUtils.stringLengthConstraintMatches`
+- **Breaking**: Removes deprecated `ionSystem()` function from PartiQLCompilerBuilder and PartiQLParserBuilder
