Jeremy Davis 已经宣布推出 TurnKey Linux 15.0 的第一个发布候选版本，这是即将推出的专为高度专业服务器设计的虚拟设备的新版本。
新版从 Debian 8/Jessie 升级到了 9/Stretch，以及下面的这些变化：
Use of new union filesystem (running live and in TKLDev) OverlayFS - new default in Stretch; v14.x and earlier used auFS
Updates for Confconsole; Let's Encrypt module (we also hope to backport these to the Jessie package)
Webmin - Update to latest v1.881; new modern default theme: 'Authentic'. Authentic theme uses a few more resources, but looks very sexy!
Webshell - now using Debian's package (rather than our own fork)
SystemD now default init system on all builds (SysvInit was still used on some v14.x builds)
Security - Reproducible TurnKey packages; thanks to Chris Lamb for his efforts there
Security hardening - courtesy of long time TurnKey contributor; John Carver, we have some nice hardening tweaks, including security improvements to: postfix, ssh & kernel sysctl variables/options (plus easy way to disable kernel hardening)
Inclusion of fail2ban - only an MVP implementation protecting SSH, but it's a start!
