+Package Versioning
+===================
+
+We use Semantic Versioning for our releases. Each version number is in the format MAJOR.MINOR.PATCH, where:
+
+- **MAJOR** version increments indicate incompatible API changes,
+- **MINOR** version increments indicate added functionality in a backward-compatible manner,
+- **PATCH** version increments indicate backward-compatible bug fixes.
