==========
Support for the old version of Vimeo's OAuth API (the `vimeo-oauth`
configuration block) has been dropped. It's unlikely anyone was using this,
since you haven't been able to register new API keys for it in years (it was
superseded by a newer OAuth API, which CyTube does not support), and in fact I
lost my credentials for this API and no longer have a way to test it.
Vimeo videos can still be added -- the metadata will be queried from the
anonymous API which has been the default since the beginning.

==========
The `stats` database table and associated ACP subpage have been removed in favor
of integration with [Prometheus](https://prometheus.io/). You can enable
Prometheus reporting by copying `conf/example/prometheus.toml` to
`conf/prometheus.toml` and editing it to your liking. I recommend integrating
Prometheus with [Grafana](https://grafana.com/) for dashboarding needs.
The particular metrics that were saved in the `stats` table are reported by the
following Prometheus metrics:
* Channel count: `cytube_channels_num_active` gauge.
* User count: `cytube_sockets_num_connected` gauge (labeled by socket.io
transport).
* CPU/Memory: default metrics emitted by the
[`prom-client`](https://github.com/siimon/prom-client) module.
More Prometheus metrics will be added in the future to make CyTube easier to
monitor :)

The latest commit upgrades `socket.io` to version 2.0, a major version change
from 1.4. This release improves performance by switching to `uws` for the
websocket transport, and fixes several bugs; you can read about it
[here](https://github.com/socketio/socket.io/releases/tag/2.0.0).
For browser clients, the upgrade should basically just work with no
intervention. For node.js clients, all that is needed is to upgrade
`socket.io-client` to 2.0. For other clients, work required may vary depending
on whether the implementation has compatibility problems with 2.0.

==========
The latest commit drops support for node.js versions below 6 (the [current
LTS](https://github.com/nodejs/LTS#lts-schedule1)). This is to allow the babel
preset to avoid generating inefficient code to polyfill ES2015+ features that
are now implemented in the node.js core.
New versions of node.js can be downloaded from the [node.js
website](https://nodejs.org/en/download/), if they are not already available in
your distribution's package manager.

==========
Polls are now more strictly validated, including the number of options. The
default limit is 50 options, which you can configure via `poll.max-options`.

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.
2016-01-06
==========
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.

==========
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;
```
2015-09-21
==========
* 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.
