This version significantly reworked the internal undocumented classes and functions. If you used the undocumented API you would probably need to adjust your code. Type checker like mypy can be very useful for this.

• @setter_private can now be used in overrides.
• Added assertDbusSignalEmits method to IsolatedDbusTestCase. Can be used to assert that a D-Bus signal was emitted inside the async with block.
• Added sdbus.utils.parse_get_managed_objects function. Can be used to parse the ObjectManager's get_managed_objects method data to classes and Python attribute names.
• Added a handle that is returned by export_to_dbus and export_with_manager methods. This handle can be used to explicitly control when object is accessible from D-Bus. (requested by @dragomirecky)

• Fixed async D-Bus properties not having a proper generic typing. (reported by @ValdezFOmar)
• Fixed build not working when systemd has a minor version suffix.
• Fixed being unable to name arguments in D-Bus introspection when method has no return arguments. (reported by @colazzo)
• Fixed serving D-Bus methods that return a single struct. (reported by @colazzo)
• Fixed sending extremely large D-Bus messages getting stuck. (reported by @colazzo)

• Improved interface generator handling of multiple uppercase letters sequences. For example, ACTIVATE_CONNECTION would before be converted to a_c_t_i_v_a_t_e__c_o_n_n_e_c_t_i_o_n and after to activate_connection. (reported by @bhattarabi)
• Improved python formatting generated by interface code generator.
• Added option --block to generate blocking interface code. (requested by @zhanglongqi and @MathisMARION)

• Fixed docstrings still being present even if python was configured with --without-doc-strings.
• Fixed interface generator crashing when a rare write-only property is encountered. (reported by @gotthardp)
• Fixed async interfaces iterating over all members during initialization. (reported by @gotthardp)
• Fixed TypeError: Dbus type '\x00' is unknown being raised when trying to read from a message more than one time. (reported by @IB1387 and @asmello)
• Fixed missing class body when generating code for interface without members.

• Added support for None signals without data.
• Added boolean flags for the name request functions which can be used to specify replacements or queueing.
• Added sdbus.utils.parse_properties_changed helper function. Parses signal data to python member names and values.
• Added sdbus.utils.parse_interfaces_added helper function. Parses signal data to path, python class and python member names and values.
• Added sdbus.utils.parse_interfaces_removed helper function. Parses signal data to path and python class.
• Added setter_private decorator to async properties. Private setter can only be called locally but to D-Bus property will appear as read only.
• Added new exceptions for when D-Bus name requests fail.
  • SdBusRequestNameExistsError: Someone already owns name.
  • SdBusRequestNameAlreadyOwnerError: Caller already owns name.
  • SdBusRequestNameInQueueError: Name request queued up.

• Moved all exceptions to sdbus.exceptions module. For backwards compatibility old exceptions will be available from the root module until the version 1.0.0.

• Fixed autodoc adding dbus_method to dbus methods names
• Fix async D-Bus name requests not raising appropriate exceptions.
• Fixed request_default_bus_name being an async function. For backwards compatibility it returns an awaitable that raises a warning.

• Added on_unknown_member option to the properties_get_all_dict method. Specifies the action on what to do with unknown property. ("error" (default), "ignore", "reuse")

• Fixed autodoc regressions introduced in 0.10.1. Properties and signals headers have been redesigned.
• Fixed PropertiesChanged signal emitting only the newest object path.

• Added catch_anywhere method to dbus signals. Creates an async iterator which yields object path that emitted signal and signal data. Can be called from class but requires explicit service name in that case.
• Added properties_get_all_dict() method to DbusInterfaceCommonAsync and DbusInterfaceCommon classes. Retrieves all D-Bus object properties as a dictionary where keys are member names translated to Python names and values are property values.

• Mapped all built-in Python exceptions to D-Bus errors.
• Default bus connection now uses context/thread-local storage. This is potentially breaking in code that used bus in a different threads or contexts.
• Added map_exception_to_dbus_error which lets mapping of any exception to D-Bus error name.
• D-Bus interfaces and member names are now verified before exporting to D-Bus. A helpful error message will be returned if verification fails.
• Added ability to export and track objects with ObjectManager.
• Added sdbus.unittest.IsolatedDbusTestCase which is a test case that runs on a separated D-Bus instance. Requires dbus-daemon command be installed.
• Allow replacing the default bus. Changing default bus will not have effect on existing objects which will continue to use the old bus.

• Fixed non-mapped errors in methods called from D-Bus not returning generic error.
• Fixed errors in properties always returning Access Denied instead of specific or generic D-Bus errors.
• Fixed str and int subclasses not being accepted on fast API.
• Fixes trying to process a disconnected bus and causing high CPU usage.
• Marked autodoc extension safe for parallel reading and writing.

• pkg-config is now required when building from source.
• Added support for Alpine Linux and any other distros using elogind instead of systemd.
• Improved PropertiesChanged signal emissions for python objects.
• Fixed python D-Bus methods that return single struct.

• Fixed missing header file from the source package.

• Deprecated DbusInterfaceCommonAsync._connect and DbusInterfaceCommonAsync.new_connect in favor of DbusInterfaceCommonAsync._proxify and DbusInterfaceCommonAsync.new_proxy respectively.

• Added gen-from-connection command to module that generates interface classes from run-time introspection. Takes service name and one or more object paths as arguments. Outputs to stdout.
• Added sd_bus_open_system_remote call that opens a remote system bus through SSH.
• Added sd_bus_open_system_machine and sd_bus_open_user_machine calls that open a bus connection inside systemd-nspawn containers.

• Typing stub will raise an exception when called in case the C module failed to load. This should reduce crypting errors in case the module failure.
• Interface generator now skips standard interfaces such as org.freedesktop.DBus.Introspectable

• Added limited API module. This has advantage of working on multiple Python versions but 5% performance penalty. PyPI will probably use the limited API module.
• Fixed any libsystemd errors causing a segmentation fault.

• Fixed unmapped errors not being raised properly.

• Added binary packages to PyPI. No more issues with libsystem versions.
• BREAKING Moved proxies from sdbus.proxies, sdbus.async_proxies to sdbus_async and sdbus_block.
• Added org.freedesktop.DBus.ObjectManager interface and a base interface with it.
• Added org.freedesktop.DBus.Properties interface to base interface.
• Added autodoc extension.
• Added interface code generator.
• Added request_default_bus_name to request name on default bus in blocking order.
• Added SdBus.request_name to requests name in blocking order. Useful to initialize the daemons.
• Fixed any initialized dbus objects never being deleted even if there were no more references to them.
