Commit f8183bea1b37154d79db741ac2845adf282e7514 modifes the schema of the
`users` table to include a new column (`name_dedupe`) which has a `UNIQUE`
constraint.  This column is populated with a modified version of the user's name
to prevent the registration of usernames which are bitwise distinct but visually
similar.  'l', 'L', and '1' are all mapped to '1'; 'o', 'O', and '0' are all
mapped to '0'; '\_' and '-' are mapped to '\_'.  On first startup after
upgrading, the new column will be added and populated.

This replaces the earlier solution which was put in place to mitigate PR#489 but
was overly-restrictive since it wildcarded these characters against *any*
character, not just characters in the same group.

The dependency on `sanitize-html`, which previously pointed to a fork, has now
been switched back to the upstream module.  XSS filtering has been turned off
for the chat filter replacement itself (since this provides no additional
security), and is now only run on the final chat message after filtering.
Certain chat filters and MOTDs which relied on syntactically incorrect HTML,
such as unclosed tags, may have different behavior now, since `sanitize-html`
fixes these.

After upgrading the dependency on `yamljs`, you may see this error if you didn't
notice and correct a typo in the config.yaml template:

    Error loading config file config.yaml:
    { [Error: Unexpected characters near ",".]
      message: 'Unexpected characters near ",".',
      parsedLine: 88,
      snippet: 'title: \'CyTube\',' }

The fix is to edit config.yaml and remove the trailing comma for the `title:`
property under `html-template`.  If there are other syntax errors that the old
version didn't detect, you will need to correct those as well.

Longer term, I am looking to move away from using `yamljs` to parse
configuration because it's a little buggy and the current configuration system
is confusing.

Google Drive changed the URL schema for retrieving video metadata, which broke
CyTube's Google Drive support, even with the userscript.  I have updated the
userscript source with the new URL, so server administrators will have to
regenerate the userscript for their site and users will be prompted to install
the newer version.

Additionally, fixing Drive lookups required an update to the `mediaquery`
module, so you will have to do an `npm install` to pull that fix in.

A few weeks ago, the previous Google Drive player stopped working.  This is
nothing new; Google Drive has consistently broken a few times a year ever since
support for it was added.  However, it's becoming increasingly difficult and
complicated to provide good support for Google Drive, so I've made the decision
to phase out the native player and require a userscript for it, in order to
bypass CORS and allow each browser to request the video stream itself.

See [the updated documentation](docs/gdrive-userscript-serveradmins.md) for
details on how to enable this for your users.

A new dependency has been added on `cytube-common`, a module that will hold
common code shared between the current version of CyTube and the upcoming work
around splitting it into multiple services.  You will need to be sure to run
`npm install` after pulling in this change to pull in the new dependency.

==========

This release updates socket.io to version 1.4.0.  The updates to socket.io
include a few security-related fixes, so please be sure to run `npm install`
to ensure the updated version is installed before restarting your CyTube server.

  * https://github.com/socketio/engine.io/commit/391ce0dc8b88a6609d88db83ea064040a05ab803

==========

In order to support future clustering support, the legacy `/sioconfig`
endpoint is being deprecated.  Instead, you should make a request to
`/socketconfig/<channel name>.json`.  See [the
documentation](docs/socketconfig.md) for more information.

2015-10-04
==========

  * The channel data storage system has been refactored a bit.  For
    compatibility, the default remains to store JSON objects for each channel in
    the `chandump` folder, however there is now also the option of storing
    channel data in the database.  You can take advantage of this by setting
    `channel-storage: type: 'database'` in your `config.yaml`.
    - In order to migrate existing channel data from the `chandump` files to the
      database, run `node lib/channel-storage/migrate.js`.
  * The database storage method uses foreign keys to associate the channel data
    with the corresponding row in the `channels` table.  This requires that the
    tables be stored using the InnoDB engine rather than MyISAM.  If your CyTube
    tables defaulted to MyISAM, you can fix them by running

    ```sql
    ALTER TABLE `channels` ENGINE = InnoDB;
    ```

  * CyTube is now transpiled with [babel] to allow the use of ES6/ES2015
    features.  All source files have been moved from `lib` to `src`.
  * Running `npm install` or `npm run postinstall` will prompt you to
    build from `src` to `lib`.
  * Running `npm run build-server` will run the build script without any
    prompts.
  * After updating with `git pull`, you should run `npm install` or `npm run
    build-server` in order to rebuild after the changes.

==========

  * CyTube now supports subtitles for Google Drive videos.  In order to take
    advantage of this, you must upgrade mediaquery by running `npm install
    cytube/mediaquery`.  Subtitles are cached in the google-drive-subtitles
    folder.

2015-07-07
==========

  * CyTube and CyTube/mediaquery have both been updated to use
    calzoneman/status-message-polyfill to polyfill res.statusMessage on older
    versions of node (e.g., v0.10).  After pulling, run `npm install` to update
    this dependency.  This fixes an issue where HTTP status messages from
    mediaquery were reported as `undefined`, and removes the need for manually
    looking up status messages in `lib/ffmpeg.js`.

2015-07-06
==========

  * As part of the video player rewrite, Google Drive and Google+ metadata
    lookups are now offloaded to CyTube/mediaquery.  After pulling the new
    changes, run `npm install` or `npm update` to update the mediaquery
    dependency.

  * `www/js/player.js` is now built from the CoffeeScript source files in the
    `player/` directory.  Instead of modifying it directly, modify the relevant
    player implementations in `player/` and run `npm run build-player` (or `node
    build-player.js`) to generate `www/js/player.js`.

  * Also as part of the video player rewrite, the schema for custom embeds
    changed so any custom embeds stored in the `channel_libraries` table need to
    be updated.  The automatic upgrade script will convert any custom embeds
    that are parseable (i.e., not truncated by the width of the `id` field using
    the old format) and will delete the rest (you may see a lot of WARNING:
    unable to convert xxx messages-- this is normal).  Custom embeds in channel
    playlists in the chandumps will be converted when the channel is loaded.
