+Release notes — pyappengine 0.7
+================================
+
+
+Documentation
+-------------
+- Added full API reference (Google-style docstrings on all public classes and
+  methods: AppEngine, CommandsLoader, Commands, AEErrs, AppEngineException).
+- Set up MkDocs with Material theme and mkdocstrings for auto-generated
+  documentation site.
+- Added docs/index.md (overview and quick-start example).
+- Added docs/getting-started.md (project structure, module authoring guide,
+  dependency declaration, help system, error handling).
+- Added docs/api.md (API reference page, auto-generated from docstrings).
+
+
+Tests
+-----
+- Added test suite based on pytest and pytest-cov (88% → 91% coverage).
+- tests/conftest.py: shared fixtures and SampleModule helper class.
+- tests/test_errors.py: tests for is_number, AEErrs, AppEngineException.
+- tests/test_commands.py: tests for Commands (val_to_print, logging, stop,
+  help, list_modules, execute_command, dispatch).
+- tests/test_commands_loader.py: tests for dynamic module loading, nickname
+  override, config section injection, dependency injection (list and dict
+  forms), threaded module lifecycle.
+- tests/test_app_engine.py: tests for AppEngine init, config parsing, log
+  setup, stop mechanism.
+
+
+Bug fixes
+---------
+- AEErrs.__str__: ERROR_MESSAGES was keyed by enum members but looked up by
+  integer value (.value). Fixed to look up by enum member.
+- execute_command: after resolving an underscore/hyphen module alias, the
+  original (non-aliased) name was still used for dispatch, causing a KeyError.
+  Fixed to use the resolved alias.
+- execute_command: when parsing "help <module>" (no function name), args were
+  not cleared before dispatch. This caused cmd_help() to receive the module
+  name as an argument and return "No command with this name". Fixed to clear
+  args and kwargs after resolving the module name.
+
+
+Project / packaging
+-------------------
+- pyproject.toml: added optional dependency groups [docs] and [dev].
+- pyproject.toml: added [tool.pytest.ini_options] (testpaths, pythonpath,
+  default coverage options).
+- .gitignore: added site/, .coverage, htmlcov/, .pytest_cache/.
+- README.md: added Development section (installation, running tests, coverage
+  reports, documentation preview and build).
