=============================================================
           + Added feature or noticeable improvement
           - Bug fix or something removed
           * Changed or Information
           ! Important - Take note!
=============================================================

=== Server Release 3.0.13.8  19 july 2017
 + Server Query connections now have a combined maximum buffer size. When this limit is exceeded,
   the connection using the most memory is closed. The buffer size is controlled by the command
   line variable "query_buffer_mb". The default is 20, which means the maximum amount of buffered
   data is 20 megabyte. The mimimum is 1 megabyte. Make sure to only enter positive integer numbers
   here.
 * Connecting to the server query port, now counts as 1 command, with regard to flood protection.
 - Fix client able to connect with no nickname

=== Server Release 3.0.13.7  10 july 2017
 - Fixed server query clients now honor name bans
 - Fixed assert when client sends oversized voice packets
 - Fixed crash when deleting channel without correct file permissions
 - Fixed permissions issue when creating channels

=== Server Release 3.0.13.6  9 november 2016
 - Fixed virtual server stops responding to clients
 - TSDNS server now also listens on ipv6 when available
 * TSDNS server Documentation updated
 
=== Server Release 3.0.13.5  24 october 2016
 - not logging received packets with 0 bytes any more
 - fixed ftinitdownload/ftinitupload can hang on server query
 
=== Server Release 3.0.13.4  7 september 2016
 + "Error opening file: No such file or directory" message now includes filename
 - Fixed server crash when ipv6 client connects while using MariaDB (or MySQL) server
 - Database plugins are now checked more thoroughly at server startup
 ! To fix the problem with MariaDB, the server needs to alter columns in the client and bindings
   table. For large databases, this can take a while. It is recommended that all ts3servers that use
   the same database, are stopped and then one new ts3server is started first which does the update.
   After this, the other instances can be started too.
   
=== Server Release 3.0.13.3  19 august 2016
 - fixed a problem where virtual servers refuse to start due to invalid flags or order
 - fixed a crash in fix crash on servergroupautodelperm / servergroupautoaddperm

=== Server Release 3.0.13.2  15 august 2016
 - fixed a crash introduced in 3.0.13.1
 - fixed a deadlock in the server causing some instances to hang / be unresponsive
 - fixed a crash reported by a customer.

=== Server Release 3.0.13.1  15 august 2016
 - fixed several vulnerabilities.

=== Server Release 3.0.13  1 august 2016
 + ipv6 support
 + improved database performance
 + improved snapshot create/deploy performance
 + Enable "tcp_nodelay" option for server query (less latency)
 + bindinglist command now has a new parameter "subsystem"
 - file transfer now only accepts connections from ip addresses that have started an upload / 
   download. There is a reserve of 20 slots that are allowed to connect even though that particular
   ip address did not start an upload/download. This is to support exotic client routing
   configurations like tcp load balancers.
 - fixed incorrect filetransfer port reported in instanceinfo
 - binding voice to the any address (0.0.0.0 / 0::0), which is the default behaviour of the server,
   now supports clients connecting to all addresses instead of just the default ip of the network
   interface.
 - fixed assertion in puzzle feature (Thanks to Schlumpi for helping us find this)
 - fixed virtual server log and bindinglist for voice showing multiple senseless bindings
 * file transfer now only allows an idle time of 2 seconds after connect
 * new file transfer implementation
 * updated sqlite to 3.11.1
 * sqlite db now uses WAL as journal mode
 ! the new file transfer routines on unix systems now depend on async io (aio*) routines. For
   freebsd this probably means you need to load the aio kernel module using 'kldload aio'
 ! for server query users: ftinitupload/download replies may now omit the ip parameter. If it is
   omitted, it means the transfer should be started on the same ip that was currently used by the
   server query ip.
 ! for ftinitupload/download there is now an optional "proto" parameter. See the server query manual
   for more info.

=== Server Release 3.0.12.4  27 april 2016

 + added "virtualserver_min_android_version" and "virtualserver_min_ios_version" to specifically
   set the minimal allowed client versions for android and ios on the server.
 + added "-mapping" to the serversnapshotdeploy command. This optional parameters will add a mapping
   of the old and new channelid's in the return
 + Grouped several SQL queries together into one statement which improves performance
 - fixed clientdbfind command returning false entries

 ! Removed "virtualserver_max_upload_total_bandwidth" and 
   "virtualserver_max_download_total_bandwidth" from the server template if the value was "-1"
 ! The server binaries file names now do NOT have the platform suffixes any more. They are all
   called "ts3server"
 ! The OSX version is now 64 bit only. OSX 10.7 is now the minimum supported version.
 ! Some SQL queries changed or added. If you use custom SQL queries, please take note of this.
 ! The minimum supported FreeBSD version for the server is 10.1 from now on. Release 3.0.13 (next)
   will need a libc++ from ports/pkg or FreeBSD 10.2.

 ! Starting this release, TS3 servers will not support the Mac OSX PowerPC architecture.
 ! Starting this release the Windows version of the server requires an SSE2 capable CPU.
 ! Starting 3.0.12 (next release), TS3 server won't support OSX 10.6 or lower.
 ! Starting this release, the MySQL database plugin has been replaced by a MariaDB plugin. Please
   read doc/update_mysql_to_mariadb.txt for instructions on how to update. Also note the default
   character set for the database is now 'utf8mb4', which means the server needs to be at least
   MySQL 5.5.3 or MariaDB 5.5 .
 ! When a new database is created, we will be using a few extra defaults for the Guest Server Query
   group. Permissions for existing databases will be left untouched.
   The new defaults for the Guest Server Query group should prevent the Server Query from being
   abused with spam. The extra permissions are:
   * b_channel_join_permanent = false, negate = true, skip = true
   * b_channel_join_semi_permanent = false, negate = true, skip = true
   * b_channel_join_temporary = false, negate = true, skip = true
   * b_channel_create_permanent = false, negate = true, skip = true
   * b_channel_create_semi_permanent = false, negate = true, skip = true
   * b_channel_create_temporary = false, negate = true, skip = true
   * b_client_server_textmessage_send = false, negate = true, skip = true
   * b_client_channel_textmessage_send = false, negate = true, skip = true
   * b_client_offline_textmessage_send = false, negate = true, skip = true
   * i_client_private_textmessage_power = -1, negate = true, skip = true
   * i_client_poke_power = -1, negate = true, skip = true
 ! If only 1 serveradmin is logged into the query, this serveradmin can select any server (use)
   regardless of the client limit.
 ! The "Wan IP" feature of the windows server has been removed as it does not work any more.
   If you want to know your wan ip address, use an existing free service like http://ipinfo.io
 + Updated ip2location database
 + Better checking and better error message for errors with query white/blacklists.
 - Fixed crash relating to invalid ip addresses on FreeBSD.
 - Fixed a possible crash during client connect.
 - Fixed channel event notifications stop working after a while.
 - Fixed query logins getting permissions on other virtual servers.
 - Fixed crash when deleting complaints.
 - Fixed issue where clients were not deleted from the database after dbclientkeepdays when
   connecting several TS3 servers to the same database with different dbclientkeepdays values.
 - The server instance no longer starts copies of virtual servers.
 - Guest ServerQuery user now always has default server query group, even while using a virtual
   server.
 - Instance server group permissions now honor the negate flag.
 - Temporary passwords and tokens(privilege keys) of a client are deleted when the client is deleted
   from the database.
 - Complaints of and about a client are deleted when the client is deleted from the database.
 - Fixed possible server hang with query connections.
 - ts3server_startscript.sh restart now works with parameters.
 - ts3server_startscript.sh does a better test for FreeBSD.
