CHANGELOG.md

@@ -6,6 +6,9 @@
 - Add service aliases via GacelaConfig::addAlias()
 - Add protected services via GacelaConfig::addProtected()
 - Add `Gacela::getRequired()` and `Locator::getRequired()` methods for type-safe service resolution that throws `ServiceNotFoundException` instead of returning null
+- Add `ContainerCompiler` for compiling container configuration to PHP code
+- Add `container:compile` command to pre-compile container for production deployment
+- Enhance Console facade and factory with container compilation support
