Jeremy Davis 已經宣佈推出 TurnKey Linux 15.0 的第一個發佈候選版本，這是即將推出的專為高度專業服務器設計的虛擬設備的新版本。
新版從 Debian 8/Jessie 升級到了 9/Stretch，以及下面的這些變化：
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!
TurnKey Linux 是基於 Debian 的虛擬應用程序庫，它將一些最好的開放源碼軟件集成到完備可用的解決方案中。每一個虛擬應用程序都為易用性進行了優化，並能在數分鐘內就部署在裸機、虛擬機及雲中。
每一個虛擬應用都可以光盤鏡像或是虛擬機鏡像的形式獲得，而這份仍在增長的應用列表包括 Bugzilla、Django、Drupal、File Server、Joomla、LAMP、Magento、Mantis、MediaWiki、MoinMoin、Moodle、MovableType、MySQL、Openbravo、phpBB、PostgreSQL、ProjectPier、Rails、Revision Control、StatusNet、Apache Tomcat、Torrent Server、Trac、TWiki、vtiger、WordPress、Zimra 及其他。
