 * Relays public channel messages between multiple mattermost, IRC, XMPP, Gitter, Slack, Discord, Telegram, Rocket.Chat, Hipchat (via xmpp), Matrix and Steam. 
  Pick and mix.
-* Matterbridge can also work with private groups on your mattermost/slack.
+* Support private groups on your mattermost/slack.
 * Allow for bridging the same bridges, which means you can eg bridge between multiple mattermosts.
 * The bridge is now a gateway which has support multiple in and out bridges. (and supports multiple gateways).

Wim	c4b75e5754	Download files from slack and reupload to mattermost (slack/mattermost). Closes #255 Refactor message.Extra to a map[string][]interface{} to have a bit more flexibility for stuffing extra stuff. For attached files from slack, files < 1MB size get downloaded (in memory), and get put into Extra["file"][]config.FileInfo (containing a pointer to the buffer and the filename). This is not async so slack channels with lots of attached files may suffer a slowdown. (the download timeout is set at 5 seconds).	2017-09-21 22:35:21 +02:00
