 # Changelog
 
+## 2.1.0
+
+### Minor Changes
+
+- [#31](https://github.com/Semantu/linked/pull/31) [`eb88865`](https://github.com/Semantu/linked/commit/eb8886564f2c9663805c4308a834ca615f9a1dab) Thanks [@flyon](https://github.com/flyon)! - Properties in `select()` and `update()` now support expressions — you can compute values dynamically instead of just reading or writing raw fields.
+
+  ### What's new
+
+  - **Computed fields in queries** — chain expression methods on properties to derive new values: string manipulation (`.strlen()`, `.ucase()`, `.concat()`), arithmetic (`.plus()`, `.times()`, `.abs()`), date extraction (`.year()`, `.month()`, `.hours()`), and comparisons (`.gt()`, `.eq()`, `.contains()`).
+
+    ```typescript
+    await Person.select((p) => ({
+      name: p.name,
+      nameLen: p.name.strlen(),
+      ageInMonths: p.age.times(12),
+    }));
+    ```
+
+  - **Expression-based WHERE filters** — filter using computed conditions, not just equality checks. Works on queries, updates, and deletes.
+
+    ```typescript
+    await Person.select((p) => p.name).where((p) => p.name.strlen().gt(5));
+    await Person.update({ verified: true }).where((p) => p.age.gte(18));
+    ```
+
+  - **Computed updates** — when updating data, calculate new values based on existing ones instead of providing static values. Pass a callback to `update()` to reference current field values.
+
+    ```typescript
+    await Person.update((p) => ({ age: p.age.plus(1) })).for(entity);
+    await Person.update((p) => ({
+      label: p.firstName.concat(" ").concat(p.lastName),
+    })).for(entity);
+    ```
+
+  - **`Expr` module** — for expressions that don't start from a property, like the current timestamp, conditional logic, or coalescing nulls.
+
+    ```typescript
+    await Person.update({ lastSeen: Expr.now() }).for(entity);
+    await Person.select((p) => ({
+      displayName: Expr.firstDefined(p.nickname, p.name),
+    }));
+    ```
+
+  Update expression callbacks are fully typed — `.plus()` only appears on number properties, `.strlen()` only on strings, etc.
+
+  ### New exports
+
+  `ExpressionNode`, `Expr`, `ExpressionInput`, `PropertyRefMap`, `ExpressionUpdateProxy<S>`, `ExpressionUpdateResult<S>`, and per-type method interfaces (`NumericExpressionMethods`, `StringExpressionMethods`, `DateExpressionMethods`, `BooleanExpressionMethods`, `BaseExpressionMethods`).
+
+  See the [README](./README.md#computed-expressions) for the full method reference and more examples.
