Changes

• Completely revamped the group synchronization system to work both ways (Discord <-> Minecraft) using Vault and while players are offline
• The topic updater’s default of 5 minutes changed to 10 minutes to comply with Discord's recent rate limit change. Minimum allowed time has been changed from 5 minutes to 10 minutes.
• The DiscordChatChannelPrefix option was renamed to DiscordChatChannelPrefixRequiredToProcessMessage because people didn't know what it's purpose was, and didn't read the comment
• Changed all "sleep interrupted" log messages to debug instead of debug/warning
• Couple privacy oriented changes for debug reports
• DiscordChatChannelConsoleCommandPrefix no longer requires a space after the prefix
• The MCDiscordReserializer config option was split into 3 (Broadcast, Minecraft -> Discord, Discord -> Minecraft)
• The permissions.txt file of debug reports has more permission info as well as console, guild and voice permissions
• Removed the dot at the end of the /discordsrv debug response (some users have had trouble with the dot)
• The voice lobby's permissions aren't forced to allow everyone to join the channel
• Improved the error for illegal key size in debug reports
• Many improvements to the reloadability of DiscordSRV; it is still advised to restart the server due to plugin integrations and other reload sensitive plugins
• The update check now runs every 6 hours
• Changed the default webhook/embed avatar url to minotar.net due to unreliability with default skins on the previous api
• JDA threads are named to indicate that they’re DiscordSRV’s JDA’s threads
• The /discord command now has a permission attached to it (discordsrv.discord)
• /discord broadcast now translates mentions
• System DNS has a chance to fix itself before switching to fallback dns, configurable with: MaximumAttemptsForSystemDNSBeforeUsingFallbackDNS
• JDBC start errors are more informative now

Fixes

• Adjusted "not linked" message to say linking.yml instead of config.yml
• Changed no-break's to regular spaces in some voice.yml files to fix parsing
• PlaceholderAPI replacements no longer cause role mentions to break
• Fixed NPE after unlinking account when the user left all Discord servers the bot is in
• Properly shut down the console appender, server watchdog and remove JDA listeners on shutdown
• Added check to see if the shutdown message format contains placeholders; to skip placeholder replacement if there are no placeholders (replacement takes ages during shut down)
• Fixed not being able to have a number at the beginning of database name (now encased in backticks)
• Added Class#forName for the MySQL driver (sometimes required for the class to get loaded)
• Made the voice module thread safe
• Connections & PreparedStatements are closed properly now

• Support for UltimateChat 1.9.0

The PebbleHost startup message has been removed. Pebble has mostly dissolved their partnership system. They're still a good budget-oriented host, though. Maybe check 'em out.
