+
+## 0.9 (2021-08-31)
+
+* Enable the hash '#' for the `addresses` of a non-distributed application.
+
+* Add `supvisorsctl` to pally the lack of support of `supervisorctl` when used with `--serverurl URL` option.
+  See related [Supervisor Issue #1455](https://github.com/Supervisor/supervisor/issues/1455).
+
+* Provide `breed.py` as a binary of **Supvisors**: `supvisors_breed`.
+  The script only considers group duplication as it is fully valid to include multiple times a program definition
+  in several groups.
+
+* Move the contents of the `[supvisors]` section into the `[rpcinterface:supvisors]` section and benefit from the
+  configuration structure provided by Supervisor. The `[supvisors]` section itself is thus obsolete.
+
+* Remove deprecated support of `pattern` elements.
+
+* Fixed issue when using the Web UI Application page from a previous launch.
+
+* Invert the stop sequence logic, starting from the greatest ``stop_sequence`` number to the lowest one.
+
+* When ``stop_sequence`` is not set in the rules files, it is defaulted to the ``start_sequence`` value.
+  With the new stop sequence logic, the stop sequence is by default exactly the opposite of the start sequence.
+
+* Fixed Nodes column width for `supervisorctl application_rules`.
+
+* `CHANGES.rst` replaced with `CHANGES.md`.
+
+* 'Scenario 3' has been added to the **Supvisors** use cases.
+
+* A 'Gathering' configuration has been added to the **Supvisors** use cases. It combines all uses cases.
+
+* Update documentation.
+
+
+## 0.8 (2021-08-22)
+
+* Fixed exception in `INITIALIZATION` state when the *Master* declared by other nodes is not RUNNING yet and
+  the *core nodes* are RUNNING.
+
+* Fixed exception when program rules and extra arguments are tested against a program unknown to the local Supervisor.
+
+* Fixed issue about program patterns that were applicable to all elements. The scope of program patterns is now limited
+  to their owner application.
+
+* Fixed issue with infinite tries of application restart when the process cannot be started due to a lack of resources
+  and `RESTART_APPLICATION` is set on the program in the **Supvisors** rules file.
+
+* Fixed issue about application state not updated after a node has become silent.
+
+* Fixed issue when choosing a node in `Starter`. Apply the requests that have not been satisfied yet for
+  non-distributed applications.
+
+* Logic for application major / minor failures reviewed.
+
+* Simplify the insertion of applications to start or stop in Commander jobs.
+
+* In the rules file, support for application patterns has been added.
+
+* In the rules file, `pattern` elements are **deprecated** and are replaced by `program` elements with a `pattern`
+  attribute instead of a `name` attribute.
+  Support for `pattern` elements will be removed in the next version of **Supvisors**.
+
+* Node aliases have been added to the rules file.
+
+* Add the current node to all pages of Web UI to be aware of the node that displays the page.
+
+* The Web UI is updated to handle a large list of applications, nodes, processor cores and network interfaces.
+
+* In the Process page of the Web UI, expand / shrink actions are not applicable to programs that are not owned
+  by a Supervisor group.
+
+* In the application navigation menu of the Web UI, add a red light near the Applications title if any application
+  has raised a failure.
+
+* In the Application page of the Web UI, default starting strategy is the starting strategy defined in the rules file
+  for the application considered.
+
+* In the Application ang Process page, the detailed process statistics can be deselected.
+
+* Titles added to the output of :program:`supervisorctl` `address_status` and `application_info`.
+
+* The XML schema has been moved to a separate file `rules.xsd`.
+
+* Remove dependency to *netifaces* as *psutil* provides the function.
+
+* 'Scenario 2' has been added to the **Supvisors** use cases.
+
+* A script `breed.py` has been added to the install package.
+  It can be used to duplicate the applications based on a template configuration and more particularly used to prepare
+  the Scenario 2 of the **Supvisors** use cases.
+
+* Update documentation.
+
+
+## 0.7 (2021-08-15)
+
+* Fixed [Issue #92](https://github.com/julien6387/supvisors/issues/92).
+  The *Master* drives the state of all **Supvisors** instances and a simplified state machine has been assigned
+  to non-master **Supvisors** instances. The loss of the *Master* instance is managed in all relevant states.
+
+* Fixed issue about applications that would be started automatically whereas their `start_sequence` is 0.
+  The regression has been introduced during the implementation of applications repair in **Supvisors 0.6**.
+
+* Enable stop sequence on *Unmanaged* applications.
+
+* In the application navigation menu of the Web UI, add a red light to applications having raised a failure.
+
+* New application rules `distributed` and `addresses` added to the **Supvisors** rules file.
+  Non-distributed applications have all their processes started on the same node chosen in accordance with the
+  `addresses` and the `starting_strategy`.
+
+* Starting strategy added to the application rules.
+
+* Fixed issue when choosing a node in `Starter`. The starting strategies considers the current load of the nodes
+  and includes the requests that have not been satisfied yet.
+
+* Fixed issue with infinite process restart when the process crashes and `RESTART_PROCESS` is set on the program
+  in the **Supvisors** rules file. When the process crashes, only the *Supervisor* `autorestart` applies.
+  The **Supvisors** `RESTART_PROCESS` applies only when the node becomes inactive.
+
+* Fixed exception when forcing the state on a process that is unknown to the local Supervisor.
+
+* Promote the `RESTART_PROCESS` into `RESTART_APPLICATION` if the application is stopped.
+
+* For the *Master* election, give a priority to nodes declared in the `forced_synchro_if` option if used.
+
+* When using the `forced_synchro_if` option and when `auto_fence` is activated, do not isolate nodes as long as
+  `synchro_timeout` has not passed.
+
+* In the `INITALIZATION` state, skip the synchronization phase upon notification of a known *Master* and adopt it.
+
+* Add reciprocity to isolation even if `auto_fence` is not activated.
+
+* In the process description of the Web UI Application page, add information about the node name.
+  In particular, it is useful to know where the process was running when it is stopped.
+
+* Start adding use cases to documentation, inspired by real examples.
+  'Scenario 1' has been added.
+
+* Documentation updated.
+
+
+## 0.6 (2021-08-01)
+
+* Applications that are not declared in the rules file are not *managed*.
+  *Unmanaged* applications have no start/stop sequence, no state and status (always STOPPED) and **Supvisors**
+  does not raise a conflict if multiple instances are running over multiple nodes.
+
+* Improve **Supvisors** stability when dealing with remote programs undefined locally.
+
+* Add expand / shrink actions to applications to the `ProcAddressView` of the Web UI.
+
+* Upon authorization of a new node in **Supvisors**, back to `DEPLOYMENT` state to repair applications.
+
+* Add RPC `change_log_level` to dynamically change the **Supvisors** logger level.
+
+* Application state is evaluated only against the starting sequence of its processes.
+
+* Fixed blocking issue when *Master* is stopped while in `DEPLOYMENT` state.
+
+* Fixed issue with applications that would not fully stop when using the `STOP_APPLICATION` starting failure strategy.
+
+* Fixed issue related to [Issue #85](https://github.com/julien6387/supvisors/issues/85).
+  An exception was raised when the program `procnum` was greater than the list of applicable nodes.
+
+* Fixed [Issue #91](https://github.com/julien6387/supvisors/issues/91).
+  Fix CSS style on the process tables in HTML.
+
+* Fixed [Issue #90](https://github.com/julien6387/supvisors/issues/90).
+  The **Supvisors** *Master* node drives the transition to `OPERATION`.
+
+* In the Web UI, set the process state color to `FATAL` when the process has exited unexpectedly.
+
+* Change the default expected loading to `0` in the program rules.
+
+* Python `Enum` used for enumerations (not available in Python 2.7).
+
+* Remove `supvisors_shortcuts` from source code to get rid of IDE warnings.
+
+* All unit tests updated from `unittest` to `pytest`.
+
+* Include this Change Log to documentation.
+
+* Documentation updated.
+
+
+## 0.5 (2021-03-01)
+
+* New option `force_synchro_if` to force the end of the synchronization phase when a subset of nodes are active.
+
+* New starting strategy `LOCAL` added to command the starting of an application on the local node only.
+
+* Fixed [Issue #87](https://github.com/julien6387/supvisors/issues/87).
+  Under particular circumstances, **Supvisors** could have multiple *Master* nodes.
+
+* Fixed [Issue #86](https://github.com/julien6387/supvisors/issues/86).
+  The starting and stopping sequences may fail and block when a sub-sequence includes only failed programs.
+
+* Fixed [Issue #85](https://github.com/julien6387/supvisors/issues/85).
+  When using `#` in the `address_list` program rule of the **Supvisors** rules file, a subset of nodes can optionally be defined.
+
+* Fixed [Issue #84](https://github.com/julien6387/supvisors/issues/84).
+  In the **Supvisors** rules file, program rules can be defined using both model reference and attributes.
+
+* The Web UI uses the default starting strategy of the configuration file.
+
+* The layout of Web UI statistics sections has been rearranged.
+
+* Fixed CSS style missing for `CHECKING` node state in tables.
+
+* Star added to the node box of the *Master* instance on the main page.
+
+* Type annotations are added progressively in source code.
+
+* Start switching from `unittest` to `pytest`.
+
+* Logs (especially `debug` and `trace`) updated to remove printed objects.
+
+* Documentation updated.
+
+
+## 0.4 (2021-02-14)
+
+* Auto-refresh button added to all pages.

+
+
+## 0.3 (2020-12-29)
+
+* Fixed [Issue #81](https://github.com/julien6387/supvisors/issues/81).
+  When **Supvisors** logfile is set to `AUTO`, **Supvisors** uses the same logger as **Supervisor**.
+
+* Fixed [Issue #79](https://github.com/julien6387/supvisors/issues/79).
+  When `FATAL` or `UNKNOWN` Process state is forced by **Supvisors**, `spawnerr` was missing in the listener payload.
+
+* Useless folder `rsc_ref` deleted.
+
+* `design` folder moved to a dedicated *GitHub* repository.
+
+* 100% coverage reached in unit tests.
+
+* Documentation updated.
+
+
+## 0.2 (2020-12-14)
+
+* Migration to **Python 3.6**.
+  Versions of dependencies are refreshed, more particularly **Supervisor 4.2.1**.
+
+* CSS of Web UI updated / simplified.
+
+* New action added to Host Process page of WebUI: `tail -f stderr` button.
+
+* New information actions added to Application page of WebUI:
