=== Server Release 3.8.0 28 May 2019

Important: This release requires GNU C library (glibc) 2.17 or later on Linux. If you need to
           check which version of glibc is installed on your system, you can use `ldd --version`,
           which usually comes with any glibc installation.
Important: Client badge information is now signed to prevent using fake data. Badges in the old
           format will not be visible on this server.
           TeamSpeak Client version 3.3.0 with support for signed badges will be available soon.

Added: The query command `banlist` now supports optional pagination parameters.
       Please refer to the ServerQuery documentation for details.
Added: Temporary passwords are now stored in the database and will be loaded on start.
Added: New command line parameters 'daemon' and 'pid_file'. This makes it possible
