Library home and playlist page overhaul
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The library home page have been completely redesigned to include:

- other users activity (listenings, playlists and favorites)
- recently imported albums

We think this new version showcases more music in a more useful way, let us know
what you think about it!

The playlist page have been updated as well.


Internationalized interface
^^^^^^^^^^^^^^^^^^^^^^^^^^^

After months of work, we're proud to announce our interface is now ready
for internationalization.

Translators have already started the work of translating Funkwhale in 8 different languages,
and we're ready to add more as needed.

You can easily get involved at https://translate.funkwhale.audio/engage/funkwhale/


Better handling of tracks with a different artist than the album artist
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Some tracks involve a different artist than the album artist (e.g. a featuring)
and Funkwhale has been known to do weird things when importing such tracks, resulting
in albums that contained a single track, for instance.

The situation should be improved with this release, as Funkwhale is now able to
store separately the track and album artist, and display it properly in the interface.


Users now have an ActivityPub Actor [Manual action required]
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

In the process of implementing federation for user activity such as listening
history, we are now making user profiles (a.k.a. ActivityPub actors) available through federation.

This does not means the federation is working, but this is a needed step to implement it.

Those profiles will be created automatically for new users, but you have to run a command
to create them for existing users.

On docker setups::

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

On non-docker setups::

    python manage.py script create_actors --no-input

This should only take a few seconds to run. It is safe to interrupt the process or rerun it multiple times.


Image thumbnails [Manual action required]
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

To reduce bandwidth usage on slow or limited connexions and improve performance
in general, we now use smaller images in the front-end. For instance, if you have
an album cover with a 1000x1000 pixel size, we will create smaller
versions of this image (50x50, 200x200, 400x400) and reference those resized version
when we don't actually need the original image.

Thumbnail will be created automatically for new objects, however, you have
to launch a manual command to deal with existing ones.

On docker setups::

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

On non-docker setups::

    python manage.py script create_image_variations --no-input

This should be quite fast but may take up to a few minutes depending on the number
of albums you have in database. It is safe to interrupt the process or rerun it multiple times.


Improved search on federated tracks list
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Having a powerful but easy-to-use search is important but difficult to achieve, especially
if you do not want to have a real complex search interface.

Github does a pretty good job with that, using a structured but simple query system
(See https://help.github.com/articles/searching-issues-and-pull-requests/#search-only-issues-or-pull-requests).

This release implements a limited but working subset of this query system. You can use it only on the federated
tracks list (/manage/federation/tracks) at the moment, but depending on feedback it will be rolled-out on other pages as well.

This is the type of query you can run:

- ``hello world``: search for "hello" and "world" in all the available fields
- ``hello in:artist`` search for results where artist name is "hello"
- ``spring in:artist,album`` search for results where artist name or album title contain "spring"
- ``artist:hello`` search for results where artist name equals "hello"
- ``artist:"System of a Down" domain:instance.funkwhale`` search for results where artist name equals "System of a Down" and inside "instance.funkwhale" library


Ensure MEDIA_ROOT, STATIC_ROOT and MUSIC_DIRECTORY_* are set explicitely [Manual action required]
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

In our default .env file, MEDIA_ROOT and STATIC_ROOT were commented by default, causing
some deployment issues on non-docker setups when people forgot to uncomment them.

From now on, those variables are uncommented, and will also be used on docker setups
to mount the volumes automatically in the docker-compose.yml file. This has been a source
of headache as well in some deployments, where you had to update both the .env file and
the compose file.

This also applies to in-place paths (MUSIC_DIRECTORY_PATH and MUSIC_DIRECTORY_SERVE_PATH),
whose values are now used directly to set up the proper Docker volumes.

This will only affect new deployments though. If you want to benefit from this on an
existing instance, do a backup of your ``.env`` and ``docker-compose.yml`` files and apply the following changes:

- Ensure ``MEDIA_ROOT`` is uncommented in your .env file and match the absolute path where media files are stored
  on your host (``/srv/funkwhale/data/media`` by default)
- Ensure ``STATIC_ROOT`` is uncommented in your .env file and match the absolute path where static files are stored
  on your host (``/srv/funkwhale/data/static`` by default)
- If you use in-place import:
    - Ensure MUSIC_DIRECTORY_PATH is uncommented and set to ``/music``
    - Ensure MUSIC_DIRECTORY_SERVE_PATH is uncommented and set to the absolute path on your host were your music files
      are stored (``/srv/funkwhale/data/music`` by default)
- Edit your docker-compose.yml file to reflect the changes:
    - Search for volumes (there should be two occurences) that contains ``/app/funkwhale_api/media`` on the right side, and
      replace the whole line with ``- "${MEDIA_ROOT}:${MEDIA_ROOT}"``
    - Search for a volume that contains ``/app/staticfiles`` on the right side, and
      replace the whole line with ``- "${STATIC_ROOT}:${STATIC_ROOT}"``
    - If you use in-place import, search for volumes (there should be two occurences) that contains ``/music:ro`` on the right side, and
      replace the whole line with ``- "${MUSIC_DIRECTORY_SERVE_PATH}:${MUSIC_DIRECTORY_PATH}:ro"``

In the end, the ``volumes`` directives of your containers should look like that::

    ...
    celeryworker
      volumes:
        - "${MUSIC_DIRECTORY_SERVE_PATH}:${MUSIC_DIRECTORY_PATH}:ro"
        - "${MEDIA_ROOT}:${MEDIA_ROOT}"
    ...
    api:
      volumes:
        - "${MUSIC_DIRECTORY_SERVE_PATH}:${MUSIC_DIRECTORY_PATH}:ro"
        - "${MEDIA_ROOT}:${MEDIA_ROOT}"
        - "${STATIC_ROOT}:${STATIC_ROOT}"
        - ./front/dist:/frontend
    ...


Removed Cacheops dependency
^^^^^^^^^^^^^^^^^^^^^^^^^^^

We removed one of our dependency named django-cacheops. It was unly used in a few places,
and not playing nice with other dependencies.

You can safely remove this dependency in your environment with ``pip uninstall django-cacheops`` if you're
not using docker.

You can also safely remove any ``CACHEOPS_ENABLED`` setting from your environment file.

- Upgrade documentation now use the correct user on non-docker setups (#265)


Invite system
^^^^^^^^^^^^^

On closed instances, it has always been a little bit painful to create accounts
by hand for new users. This release solve that by adding invitations.

You can generate invitation codes via the "users" admin interface (you'll find a
link in the sidebar). Those codes are valid for 14 days, and can be used once
to create a new account on the instance, even if registrations are closed.

By default, we generate a random code for invitations, but you can also use custom codes
if you need to print them or make them fancier ;)

Invitations generation and management requires the "settings" permission.


Removed front-end and back-end coupling
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Eventhough Funkwhale's front-end has always been a Single Page Application,
talking to an API, it was only able to talk to an API on the same domain.

There was no real technical justification behind this (only lazyness), and it was
also blocking interesting use cases:

- Use multiple customized versions of the front-end with the same instance
- Use a customized version of the front-end with multiple instances
- Use a locally hosted front-end with a remote API, which is especially useful in development

From now on, Funkwhale's front-end can connect to any Funkwhale server. You can
change the server you are connecting to in the footer.

Fixing this also unlocked a really interesting feature in our development/review workflow:
by leveraging Gitlab CI and review apps, we are now able to deploy automatically live versions of
a merge request, making it possible for anyone to review front-end changes easily, without
the need to install a local environment.


0.14.2 (2018-06-16)
-------------------

.. warning::

    This release contains a fix for a permission issue. You should upgrade
    as soon as possible. Read the changelog below for more details.

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

Enhancements:

- Added feedback on shuffle button (#262)
- Added multiple warnings in the documentation that you should never run
  makemigrations yourself (#291)

  formatting (#297)
- Added bug and feature issue templates (#299)


Permission issues on radios
^^^^^^^^^^^^^^^^^^^^^^^^^^^

Because of an error in the way we checked user permissions on radios,
public radios could be deleted by any logged-in user, even if they were not
the owner of the radio.

We recommend instances owners to upgrade as fast as possible to avoid any abuse
and data loss.


Funkwhale is now licenced under AGPL-3
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Following the recent switch made by PixelFed
(https://github.com/dansup/pixelfed/issues/143), we decided along with
the community to relicence Funkwhale under the AGPL-3 licence. We did this
switch for various reasons:

- This is better aligned with other fediverse software
- It prohibits anyone to distribute closed-source and proprietary forks of Funkwhale

As end users and instance owners, this does not change anything. You can
continue to use Funkwhale exactly as you did before :)


Apache support for websocket
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Up until now, our Apache2 configuration was not working with websockets. This is now
solved by adding this at the beginning of your Apache2 configuration file::

    Define funkwhale-api-ws ws://localhost:5000

And this, before the "/api" block::

    # Activating WebSockets
    ProxyPass "/api/v1/instance/activity" ${funkwhale-api-ws}/api/v1/instance/activity

Websockets may not be supported in older versions of Apache2. Be sure to upgrade to the latest version available.


Serving album covers in https (Apache2 proxy)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Two issues are addressed here. The first one was about Django replying with
mixed content (http) when queried for covers. Setting up the `X-Forwarded-Proto`
allows Django to know that the client is using https, and that the reply must
be https as well.

Second issue was a problem of permission causing Apache a denied access to
album cover folder. It is solved by adding another block for this path in
the Apache configuration file for funkwhale.

Here is how to modify your `funkwhale.conf` apache2 configuration::

  <VirtualHost *:443>

    ...
    #Add this new line
    RequestHeader set X-Forwarded-Proto "https"
    ...
    # Add this new block below the other <Directory/> blocks
    # replace /srv/funkwhale/data/media with the path to your media directory
    # if you're not using the standard layout.
    <Directory /srv/funkwhale/data/media/albums>
      Options FollowSymLinks
      AllowOverride None
      Require all granted
    </Directory>
    ...
  </VirtualHost>


About the makemigrations warning
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You may sometimes get the following warning while applying migrations::

    "Your models have changes that are not yet reflected in a migration, and so won't be applied."

This is a warning, not an error, and it can be safely ignored.
Never run the ``makemigrations`` command yourself.


0.14.1 (2018-06-06)

- Removed hardcoded size limit in file upload widget (#275)


Documentation:

- Added warning about _protected/music location in nginx configuration (#247)


Removed alpha-state transcoding (#271)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

A few months ago, a basic transcoding feature was implemented. Due to the way
this feature was designed, it was slow, CPU intensive on the server side,
and very tightly coupled to the reverse-proxy configuration, preventing
it to work Apache2, for instance. It was also not compatible with Subsonic clients.

Based on that, we're currently removing support for transcoding
**in its current state**. The work on a better designed transcoding feature
can be tracked in https://code.eliotberriot.com/funkwhale/funkwhale/issues/272.

You don't have to do anything on your side, but you may want to remove
the now obsolete configuration from your reverse proxy file (nginx only)::

    # Remove those blocks:

    # transcode cache
    proxy_cache_path /tmp/funkwhale-transcode levels=1:2 keys_zone=transcode:10m max_size=1g inactive=7d;

    # Transcoding logic and caching
    location = /transcode-auth {
        include /etc/nginx/funkwhale_proxy.conf;
        # needed so we can authenticate transcode requests, but still
        # cache the result
        internal;
        set $query '';
        # ensure we actually pass the jwt to the underlytin auth url
        if ($request_uri ~* "[^\?]+\?(.*)$") {
            set $query $1;
        }
        proxy_pass http://funkwhale-api/api/v1/trackfiles/viewable/?$query;
        proxy_pass_request_body off;
        proxy_set_header        Content-Length "";
    }

    location /api/v1/trackfiles/transcode/ {
        include /etc/nginx/funkwhale_proxy.conf;
        # this block deals with authenticating and caching transcoding
        # requests. Caching is heavily recommended as transcoding
        # is a CPU intensive process.
        auth_request /transcode-auth;
        if ($args ~ (.*)jwt=[^&]*(.*)) {
            set $cleaned_args $1$2;
        }
        proxy_cache_key "$scheme$request_method$host$uri$is_args$cleaned_args";
        proxy_cache transcode;
        proxy_cache_valid 200 7d;
        proxy_ignore_headers "Set-Cookie";
        proxy_hide_header "Set-Cookie";
        add_header X-Cache-Status $upstream_cache_status;
        proxy_pass   http://funkwhale-api;
    }
    # end of transcoding logic

Files management interface
^^^^^^^^^^^^^^^^^^^^^^^^^^

This is the first bit of an ongoing work that will span several releases, to
bring more powerful library management features to Funkwhale. This iteration
includes a basic file management interface where users with the "library"
permission can list and search available files, order them using
various criterias (size, bitrate, duration...) and delete them.

New "upload" permission
^^^^^^^^^^^^^^^^^^^^^^^

This new permission is helpful if you want to give upload/import rights
to some users, but don't want them to be able to manage the library as a whole:
although there are no controls yet for managing library in the fron-end,
subsequent release will introduce management interfaces for artists, files,
etc.

Because of that, users with the "library" permission will have much more power,
and will also be able to remove content from the platform. On the other hand,
users with the "upload" permission will only have the ability to add new
content.

Also, this release also includes a new feature called "default permissions":
those are permissions that are granted to every users on the platform.
On public/open instances, this will play well with the "upload" permission
since everyone will be able to contribute to the instance library without
an admin giving the permission to every single user.

Smarter album cover importer
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

In earlier versions, covers where only imported when launching a YouTube import.
Starting from this release, covers will be imported regardless of the import mode
(file upload, youtube-dl, CLI, in-place...). Funkwhale will look for covers
in the following order:

1. In the imported file itself (FLAC/MP3 only)
2. In a cover.jpg or cover.png in the file directory
3. By fetching cover art from Musibrainz, assuming the file is tagged correctly

This will only work for newly imported tracks and albums though. In the future,
we may offer an option to refetch album covers from the interface, but in the
meantime, you can use the following snippet:

.. code-block:: python

    # Store this in /tmp/update_albums.py
    from funkwhale_api.music.models import Album, TrackFile
    from funkwhale_api.music.tasks import update_album_cover

    albums_without_covers = Album.objects.filter(cover='')
    total = albums_without_covers.count()
    print('Found {} albums without cover'.format(total))
    for i, album in enumerate(albums_without_covers.iterator()):
        print('[{}/{}] Fetching cover for {}...'.format(i+1, total, album.title))
        f = TrackFile.objects.filter(track__album=album).filter(source__startswith='file://').first()
        update_album_cover(album, track_file=f)

Then launch it::

    # docker setups
    cat /tmp/update_albums.py | docker-compose run --rm api python manage.py shell -i python

    # non-docker setups

.. note::

    Depending on your number of albums, the previous snippet may take some time
    to execute. You can interrupt it at any time using ctrl-c and relaunch it later,
    as it's idempotent.

Music API changes
^^^^^^^^^^^^^^^^^

This release includes an API break. Even though the API is advertised
as unstable, and not documented, here is a brief explanation of the change in
case you are using the API in a client or in a script. Summary of the changes:

- ``/api/v1/artists`` does not includes a list of tracks anymore. It was to heavy
  to return all of this data all the time. You can get all tracks for an
  artist using ``/api/v1/tracks?artist=artist_id``
- Additionally, ``/api/v1/tracks`` now support an ``album`` filter to filter
  tracks matching an album
- ``/api/v1/artists/search``, ``/api/v1/albums/search`` and ``/api/v1/tracks/search``
  endpoints are removed. Use ``/api/v1/{artists|albums|tracks}/?q=yourquery``
  instead. It's also more powerful, since you can combine search with other
  filters and ordering options.
- ``/api/v1/requests/import-requests/search`` endpoint is removed as well.
  Use ``/api/v1/requests/import-requests/?q=yourquery``
  instead. It's also more powerful, since you can combine search with other
  filters and ordering options.

Of course, the front-end was updated to work with the new API, so this should
not impact end-users in any way, apart from slight performance gains.

.. note::

    The API is still not stable and may evolve again in the future. API freeze
    will come at a later point.

Flac files imports via upload
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

You have nothing to do to benefit from this, however, since Flac files
tend to be a lot bigger than other files, you may want to increase the
``client_max_body_size`` value in your Nginx configuration if you plan
to upload flac files.

Missing subsonic configuration bloc in vhost files
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Because of a missing bloc in the sample Nginx and Apache configurations,
instances that were deployed after the 0.13 release are likely to be unable
to answer to Subsonic clients (the missing bits were properly documented
in the changelog).

Ensure you have the following snippets in your Nginx or Apache configuration
if you plan to use the Subsonic API.

Nginx::

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

Apache2::

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

Instance settings interface
^^^^^^^^^^^^^^^^^^^^^^^^^^^

Prior to this release, the only way to update instance settings (such as
instance description, signup policy, federation configuration, etc.) was using
the admin interface provided by Django (the back-end framework which power the API).

This interface worked, but was not really-user friendly and intuitive.

Starting from this release, we now offer a dedicated interface directly
in the front-end. You can view and edit all your instance settings from here,
assuming you have the required permissions.

This interface is available at ``/manage/settings` and via link in the sidebar.


Storage of bitrate, size and length in database
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Starting with this release, when importing files, Funkwhale will store
additional information about audio files:

- Bitrate
- Size (in bytes)
- Duration

This change is not retroactive, meaning already imported files will lack those
informations. The interface and API should work as before in such case, however,
we offer a command to deal with legacy files and populate the missing values.

On docker setups:

.. code-block:: shell

    docker-compose run --rm api python manage.py fix_track_files


On non-docker setups:

.. code-block:: shell

    # from your activated virtualenv
    python manage.py fix_track_files

.. note::

    The execution time for this command is proportional to the number of
    audio files stored on your instance. This is because we need to read the
    files from disk to fetch the data. You can run it in the background
    while Funkwhale is up.

    It's also safe to interrupt this command and rerun it at a later point, or run
    it multiple times.

    Use the --dry-run flag to check how many files would be impacted.


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
