+  for secrets. See the documentation for more information
+
+#### Compose file version 2.0 and up
+
+- Introduced the `docker-compose top` command that displays processes running
+  for the different services managed by Compose.
+
+### Bugfixes
+
+- Fixed a bug where extending a service defining a healthcheck dictionary
+  would cause `docker-compose` to error out.
+
+- Fixed an issue where the `pid` entry in a service definition was being
+  ignored when using multiple Compose files.
+
+1.10.1 (2017-02-01)
+------------------
+
+### Bugfixes
+
+- Fixed an issue where presence of older versions of the docker-py
+  package would cause unexpected crashes while running Compose
+
+- Fixed an issue where healthcheck dependencies would be lost when
+  using multiple compose files for a project
+
+- Fixed a few issues that made the output of the `config` command
+  invalid
+
+- Fixed an issue where adding volume labels to v3 Compose files would
+  result in an error
+
+- Fixed an issue on Windows where build context paths containing unicode
+  characters were being improperly encoded
+
+- Fixed a bug where Compose would occasionally crash while streaming logs
+  when containers would stop or restart
+
+1.10.0 (2017-01-18)
+-------------------
+
+### New Features
+
+#### Compose file version 3.0
+
+- Introduced version 3.0 of the `docker-compose.yml` specification. This
+  version requires to be used with Docker Engine 1.13 or above and is
+  specifically designed to work with the `docker stack` commands.
+
+#### Compose file version 2.1 and up
+
+- Healthcheck configuration can now be done in the service definition using
+  the `healthcheck` parameter
+
+- Containers dependencies can now be set up to wait on positive healthchecks
+  when declared using `depends_on`. See the documentation for the updated
+  syntax.
+  **Note:** This feature will not be ported to version 3 Compose files.
+
+- Added support for the `sysctls` parameter in service definitions
+
+- Added support for the `userns_mode` parameter in service definitions
+
+- Compose now adds identifying labels to networks and volumes it creates
+
+#### Compose file version 2.0 and up
+
+- Added support for the `stop_grace_period` option in service definitions.
+
+### Bugfixes
+
+- Colored output now works properly on Windows.
+
+- Fixed a bug where docker-compose run would fail to set up link aliases
+  in interactive mode on Windows.
+
+- Networks created by Compose are now always made attachable
+  (Compose files v2.1 and up).
+
+- Fixed a bug where falsy values of `COMPOSE_CONVERT_WINDOWS_PATHS`
+  (`0`, `false`, empty value) were being interpreted as true.
+
+- Fixed a bug where forward slashes in some .dockerignore patterns weren't
+  being parsed correctly on Windows
