TeamSpeak updated to 3.10.0

[Admin]

Our TeamSpeak server has been updated to 3.10.0, hopefully all our users will see improved performance while using the server.

BETA FEATURE : the server supports IPv6 connections at 2001:41d0:800:1f6c::

We are pleased to announce that our TeamSpeak Server version 3.10.0 has left the Beta state.

We changed a lot for this release so here is our list with most important changes. Hope you like them.

• We overhauled the snapshots.
  • They are now Base64 encoded. This makes them smaller and issues with UTF 8 characters should be gone.
  • You now can encrypt your snapshot using a password. The password is AES encrypted and won't be shown in the server log in case logging was enabled.
  • We added an optional parameter to move files from existing channels into the new one. But only if channel did exist before. This won't work with snapshots before 3.10.0.
  • Older snapshots still can be applied, but you should create new ones after you did update.
• The server code got an overhaul and things should run better now (including packet loss and CPU usage).
• A file can no longer be overwritten with an upload when client has not enough 'i_ft_file_delete_power'.
• Handling of Client IDs was touched.
  • They now always increase and only start from free lowest ID when 65535 was reached.
  • The same Client ID is used again when client with same Database ID reconnects within some minutes.
• We fixed the avatar issues from 3.10.0 beta
• A FreeBSD version is available again. But make sure you use FreeBSD 11 or newer.

Here is the full change log:

## Server Release 3.10.0 6 November 2019

### Important
- TeamSpeak Client 3.3.0 or later is needed to connect to this and upcoming server releases.

### Added
- New channel property `channel_unique_identifier` that contains a channel UID that is unchanged by snapshot import/exports.
- New compressed snapshot format that is easier to use.
- New optional parameter `-keepfiles` for `serversnapshotdeploy` that doesn't delete files of channels that exist in the snapshot and on the server.
- New optional parameter `password` to snapshot commands for specifying an optional password to encrypt the snapshot. The password is always being omitted from the log files.
- New command line parameter `hints_enabled`(defaults to `1`). When enabled, the server will send permission hints to clients, that allows clients to know, if certain actions are likely to succeeded or not.

### Changed
- New embedded default license is valid until the 1st of July 2020.
- Improved TeamSpeak Server performance, and reduced packet loss on very busy servers.
- Allocation of client IDs has been changed.
- Permission `i_ft_file_delete_power` is now required to overwrite a file.

### Fixed
- "Server Admin Token" has been renamed to "Server Admin Privilege Key" in the new server window.
- Fixed a few potential crashes.
- Fixed database error when getting the same custom property assigned twice on MariaDB.
- Fixed `clientgetids` incorrectly returning `database empty result set` when more then one client was connected with the queried `cluid`.
