CHANGELOG

Simpler permission system
^^^^^^^^^^^^^^^^^^^^^^^^^

Starting from this release, the permission system is much simpler. Up until now,
we were using Django's built-in permission system, which was working, but also
quite complex to deal with.

The new implementation relies on simpler logic, which will make integration
on the front-end in upcoming releases faster and easier.

If you have manually given permissions to users on your instance,
you can migrate those to the new system.

On docker setups:

.. code-block:: shell

    docker-compose run --rm api python manage.py script django_permissions_to_user_permissions --no-input

On non-docker setups:

.. code-block:: shell

    # in your virtualenv
    python api/manage.py script django_permissions_to_user_permissions --no-input

There is still no dedicated interface to manage user permissions, but you
can use the admin interface at ``/api/admin/users/user/`` for that purpose in
the meantime.

Subsonic API
^^^^^^^^^^^^

This release implements some core parts of the Subsonic API, which is widely
deployed in various projects and supported by numerous clients.

By offering this API in Funkwhale, we make it possible to access the instance
library and listen to the music without from existing Subsonic clients, and
without developping our own alternative clients for each and every platform.

Most advanced Subsonic clients support offline caching of music files,
playlist management and search, which makes them well-suited for nomadic use.

Please head over :doc:`users/apps` for more informations about supported clients
and user instructions.

At the instance-level, the Subsonic API is enabled by default, but require
and additional endpoint to be added in you reverse-proxy configuration.

On nginx, add the following block::

    location /rest/ {
        include /etc/nginx/funkwhale_proxy.conf;
        proxy_pass   http://funkwhale-api/api/subsonic/rest/;
    }

On Apache, add the following block::

    <Location "/rest">
        ProxyPass ${funkwhale-api}/api/subsonic/rest
        ProxyPassReverse ${funkwhale-api}/api/subsonic/rest
    </Location>

The Subsonic can be disabled at the instance level from the django admin.

.. note::

    Because of Subsonic's API design which assumes cleartext storing of
    user passwords, we chose to have a dedicated, separate password
    for that purpose. Users can generate this password from their
    settings page in the web client.


Nodeinfo standard for instance information and stats
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

.. warning::

    The ``/api/v1/instance/stats/`` endpoint which was used to display
    instance data in the about page is removed in favor of the new
    ``/api/v1/instance/nodeinfo/2.0/`` endpoint.

In earlier version, we where using a custom endpoint and format for
our instance information and statistics. While this was working,
this was not compatible with anything else on the fediverse.

We now offer a nodeinfo 2.0 endpoint which provides, in a single place,
all the instance information such as library and user activity statistics,
public instance settings (description, registration and federation status, etc.).

We offer two settings to manage nodeinfo in your Funkwhale instance:

1. One setting to completely disable nodeinfo, but this is not recommended
   as the exposed data may be needed to make some parts of the front-end
   work (especially the about page).
2. One setting to disable only usage and library statistics in the nodeinfo
   endpoint. This is useful if you want the nodeinfo endpoint to work,
   but don't feel comfortable sharing aggregated statistics about your library
   and user activity.

To make your instance fully compatible with the nodeinfo protocol, you need to
to edit your nginx configuration file::

    # before
    ...
    location /.well-known/webfinger {
        include /etc/nginx/funkwhale_proxy.conf;
        proxy_pass   http://funkwhale-api/.well-known/webfinger;
    }
    ...

    # after
    ...
    location /.well-known/ {
        include /etc/nginx/funkwhale_proxy.conf;
        proxy_pass   http://funkwhale-api/.well-known/;
    }
    ...

You can do the same if you use apache::

    # before
    ...
    <Location "/.well-known/webfinger">
      ProxyPass ${funkwhale-api}/.well-known/webfinger
      ProxyPassReverse ${funkwhale-api}/.well-known/webfinger
    </Location>
    ...

    # after
    ...
    <Location "/.well-known/">
      ProxyPass ${funkwhale-api}/.well-known/
      ProxyPassReverse ${funkwhale-api}/.well-known/
    </Location>
    ...

This will ensure all well-known endpoints are proxied to funkwhale, and
not just webfinger one.

0.11 (2018-05-06)
-----------------

Upgrade instructions are available at https://docs.funkwhale.audio/upgrading.html

Special thanks for this release go to @renon:matrix.org (@Hazmo on Gitlab)
for bringing Apache2 support to Funkwhale and contributing on other issues.
Thank you!

Features:

- Funkwhale now works behind an Apache2 reverse proxy (!165)
  check out the brand new documentation at https://docs.funkwhale.audio/installation/index.html#apache2
  if you want to try it!
- Users can now request password reset by email, assuming a SMTP server was
  correctly configured (#187)

Enhancements:

- Added a fix_track_files command to run checks and fixes against library
  (#183)
- Avoid fetching Actor object on every request authentication
- Can now relaunch errored jobs and batches (#176)
- List pending requests by default, added a status filter for requests (#109)
- More structured menus in sidebar, added labels with notifications
- Sample virtual-host file for Apache2 reverse-proxy (!165)
- Store high-level settings (such as federation or auth-related ones) in
  database (#186)


Bugfixes:

- Ensure in place imported files get a proper mimetype (#183)
- Federation cache suppression is now simpler and also deletes orphaned files
  (#189)
- Fixed small UI glitches/bugs in federation tabs (#184)
- X-sendfile not working with in place import (#182)


Documentation:

- Added a documentation area for third-party projects (#180)
- Added documentation for optimizing Funkwhale and reduce its memory footprint.
- Document that the database should use an utf-8 encoding (#185)
- Foundations for API documentation with Swagger (#178)


Database storage for high-level settings
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Due to the work done in #186, the following environment variables have been
deprecated:

- FEDERATION_ENABLED
- FEDERATION_COLLECTION_PAGE_SIZE
- FEDERATION_MUSIC_NEEDS_APPROVAL
- FEDERATION_ACTOR_FETCH_DELAY
- PLAYLISTS_MAX_TRACKS
- API_AUTHENTICATION_REQUIRED

Configuration for this settings has been moved to database, as it will provide
a better user-experience, by allowing you to edit these values on-the-fly,
without restarting Funkwhale processes.

You can leave those environment variables in your .env file for now, as the
values will be used to populate the database entries. We'll make a proper
announcement when the variables won't be used anymore.

Please browse https://docs.funkwhale.audio/configuration.html#instance-settings
for more information about instance configuration using the web interface.


System emails
^^^^^^^^^^^^^

Starting from this release, Funkwhale will send two types
of emails:

- Email confirmation emails, to ensure a user's email is valid
- Password reset emails, enabling user to reset their password without an admin's intervention

Email sending is disabled by default, as it requires additional configuration.
In this mode, emails are simply outputed on stdout.

If you want to actually send those emails to your users, you should edit your
.env file and tweak the EMAIL_CONFIG variable. See :ref:`setting-EMAIL_CONFIG`
for more details.

.. note::

  As a result of these changes, the DJANGO_EMAIL_BACKEND variable,
  which was not documented, has no effect anymore. You can safely remove it from
  your .env file if it is set.


Proxy headers for non-docker deployments
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

For non-docker deployments, add ``--proxy-headers`` at the end of the ``daphne``
command in :file:`/etc/systemd/system/funkwhale-server.service`.

This will ensure the application receive the correct IP address from the client
and not the proxy's one.

In-place import
^^^^^^^^^^^^^^^

This release includes in-place imports for the CLI import. This means you can
load gigabytes of music into funkwhale without worrying about about Funkwhale
copying those music files in its internal storage and eating your disk space.

`This new feature is documented here <https://docs.funkwhale.audio/importing-music.html#in-place-import>`_
and require additional configuration to ensure funkwhale and your webserver can
serve those files properly.

**Non-docker users:**

Assuming your music is stored in ``/srv/funkwhale/data/music``, add the following
block to your nginx configuration::

    location /_protected/music {
        internal;
        alias   /srv/funkwhale/data/music;
    }

And the following to your .env file::

    MUSIC_DIRECTORY_PATH=/srv/funkwhale/data/music

**Docker users:**

Assuming your music is stored in ``/srv/funkwhale/data/music``, add the following
block to your nginx configuration::

    location /_protected/music {
        internal;
        alias   /srv/funkwhale/data/music;
    }

Assuming you have the following volume directive in your ``docker-compose.yml``
(it's the default): ``/srv/funkwhale/data/music:/music:ro``, then add
the following to your .env file::

    # this is the path in the container
    MUSIC_DIRECTORY_PATH=/music
    # this is the path on the host
    MUSIC_DIRECTORY_SERVE_PATH=/srv/funkwhale/data/music


0.9.1 (2018-04-17)
------------------

Bugfixes:

- Allow null values for musicbrainz_id in Audio ActivityPub representation
- Fixed broken permission check on library scanning and too aggressive page
  validation


0.9 (2018-04-17)
----------------

Features:

- Add internationalization support (#5)
- Can now follow and import music from remote libraries (#136, #137)


Enhancements:

- Added a i18n-extract yarn script to extract strings to PO files (#162)
- User admin now includes signup and last login dates (#148)
- We now use a proper user agent including instance version and url during
  outgoing requests


Federation is here!
^^^^^^^^^^^^^^^^^^^

This is for real this time, and includes:

- Following other Funkwhale libraries
- Importing tracks from remote libraries (tracks are hotlinked, and only cached for a short amount of time)
- Searching accross federated catalogs

Note that by default, federation is opt-in, on a per-instance basis:
instances will request access to your catalog, and you can accept or refuse
those requests. You can also revoke the access at any time.

Documentation was updated with relevant instructions to use and benefit
from this new feature: https://docs.funkwhale.audio/federation.html

Preparing internationalization
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Funkwhale's front-end as always been english-only, and this is a barrier
to new users. The work make Funkwhale's interface translatable was started
in this release by Baptiste. Although nothing is translated yet,
this release includes behind the stage changes that will make it possible in
the near future.

Many thank to Baptiste for the hard work and for figuring out a proper solution
to this difficult problem.

Upgrade path
^^^^^^^^^^^^

In addition to the usual instructions from
https://docs.funkwhale.audio/upgrading.html, non-docker users will have
to setup an additional systemd unit file for recurrent tasks.

This was forgotten in the deployment documentation, but recurrent tasks,
managed by the celery beat process, will be needed more and more in subsequent
releases. Right now, we'll be using to clear the cache for federated music files
and keep disk usage to a minimum.

In the future, they will also be needed to refetch music metadata or federated
information periodically.

Celery beat can be enabled easily::

    curl -L -o "/etc/systemd/system/funkwhale-beat.service" "https://dev.funkwhale.audio/funkwhale/funkwhale/raw/develop/deploy/funkwhale-beat.service"
    # Also edit /etc/systemd/system/funkwhale.target
    # and ensure the Wants= line contains the following:
    # Wants=funkwhale-server.service funkwhale-worker.service funkwhale-beat.service
    nano /etc/systemd/system/funkwhale.target
    # reload configuration
    systemctl daemon-reload

Docker users already have celerybeat enabled.

  (#121)


Documentation:

- Documented the upgrade process (#127)


Preparing for federation
^^^^^^^^^^^^^^^^^^^^^^^^

Federation of music libraries is one of the most asked feature.
While there is still a lot of work to do, this version includes
the foundation that will enable funkwhale servers to communicate
between each others, and with other federated software, such as
Mastodon.

Funkwhale will use ActivityPub as it's federation protocol.

In order to prepare for federation (see #136 and #137), new API endpoints
have been added under /federation and /.well-known/webfinger.

For these endpoints to work, you will need to update your nginx configuration,
and add the following snippets::

    location /federation/ {
        include /etc/nginx/funkwhale_proxy.conf;
        proxy_pass   http://funkwhale-api/federation/;
    }

    location /.well-known/webfinger {
        include /etc/nginx/funkwhale_proxy.conf;
        proxy_pass   http://funkwhale-api/.well-known/webfinger;
    }

This will ensure federation endpoints will be reachable in the future.
You can of course skip this part if you know you will not federate your instance.

A new ``FEDERATION_ENABLED`` env var have also been added to control whether
federation is enabled or not on the application side. This settings defaults
to True, which should have no consequences at the moment, since actual
federation is not implemented and the only available endpoints are for
testing purposes.

Add ``FEDERATION_ENABLED=false`` to your .env file to disable federation
on the application side.

To test and troubleshoot federation, we've added a bot account. This bot is available at @test@yourinstancedomain,
and sending it "/ping", for example, via Mastodon, should trigger
a response.



0.7 (2018-03-21)
----------------

Features:

- Can now filter artists and albums with no listenable tracks (#114)
- Improve the style of the sidebar to make it easier to understand which tab is

0.6 (2018-03-04)
----------------

Features:

- Basic activity stream for listening and favorites (#23)
- Switched to django-channels and daphne for serving HTTP and websocket (#34)

Upgrades notes
**************

This version contains breaking changes in the way funkwhale is deployed,
please read the notes carefully.

Instance timeline
^^^^^^^^^^^^^^^^^

A new "Activity" page is now available from the sidebar, where you can
browse your instance activity. At the moment, this includes other users
favorites and listening, but more activity types will be implemented in the
future.

Internally, we implemented those events by following the Activity Stream
specification, which will help us to be compatible with other networks
in the long-term.

A new settings page has been added to control the visibility of your activity.
By default, your activity will be browsable by anyone on your instance,
but you can switch to a full private mode where nothing is shared.

The setting form is available in your profile.

Switch from gunicorn to daphne
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This release include an important change in the way we serve the HTTP API.
To prepare for new realtime features and enable websocket support in Funkwhale,
we are now using django-channels and daphne to serve HTTP and websocket traffic.

This replaces gunicorn and the switch should be easy assuming you
follow the upgrade process described bellow.

If you are using docker, please remove the command instruction inside the
api service, as the up-to-date command is now included directly in the image
as the default entry point:

.. code-block:: yaml

    api:
      restart: unless-stopped
      image: funkwhale/funkwhale:${FUNKWHALE_VERSION:-latest}
      command: ./compose/django/gunicorn.sh  # You can remove this line

On non docker setups, you'll have to update the [Service] block of your
funkwhale-server systemd unit file to launch the application server using daphne instead of gunicorn.

The new configuration should be similar to this:

.. code-block:: ini

    [Service]
    User=funkwhale
    # adapt this depending on the path of your funkwhale installation
    WorkingDirectory=/srv/funkwhale/api
    EnvironmentFile=/srv/funkwhale/config/.env
    ExecStart=/usr/local/bin/daphne -b ${FUNKWHALE_API_IP} -p ${FUNKWHALE_API_PORT} config.asgi:application

Ensure you update funkwhale's dependencies as usual to install the required
packages.

On both docker and non-docker setup, you'll also have to update your nginx
configuration for websocket support. Ensure you have the following blocks
included in your virtualhost file:

.. code-block:: text

    map $http_upgrade $connection_upgrade {
        default upgrade;
        ''      close;
    }

    server {
        ...
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $connection_upgrade;
    }

Remember to reload your nginx server after the edit.

About page:

There is a brand new about page on instances (/about), and instance
owner can now provide a name, a short and a long description for their instance via the admin (/api/admin/dynamic_preferences/globalpreferencemodel/).

Transcoding:

Basic transcoding is now available to/from the following formats : ogg and mp3.

*This is still an alpha feature at the moment, please report any bug.*

This relies internally on FFMPEG and can put some load on your server.
It's definitely recommended you setup some caching for the transcoded files
at your webserver level. Check the the exemple nginx file at deploy/nginx.conf
for an implementation.

On the frontend, usage of transcoding should be transparent in the player.

Music Requests:

This release includes a new feature, music requests, which allows users
to request music they'd like to see imported.
Admins can browse those requests and mark them as completed when
an import is made.
