 ## Change-log
 
+- 2.0.0 (future)
+    - Drop support for PHP 5.x
+    - Introduce strict scalar type hints
+    - Drop deprecated functions and properties.
+
+- 1.3.0
+    - Remove generated Phar file. Users who need it should use the `build-phar.php` script to generate one.
+    - Refactor LUDecomposition to have a less awkward constructor.
+    - Split `add()` into `addMatrix()` and `addScalar()`. Deprecate `add()`.
+    - Split `subtract()` into `subtractMatrix()` and `subtractScalar()`. Deprecate `subtract()`.
+    - Split `multiply()` into `multiplyMatrix()` and `multiplyScalar()`. Deprecate `multiply()`.
+    - Add `getRowCount()` and `getColumnCount()` accessors.
+    - Deprecate `rows` and `columns` properties.
+
 - 1.2.0
     - Added `concatenateBottom($other)`
     - Added `concatencateRight($other)`
