SUSE Linux Enterprise Server 15已经发布正式版本下载，提供AMD64/Intel 64、IBM z Systems、IBM Power、ARM及Raspberry Pi架构版本。该版本和前一个SUSE Linux Enterprise Server 12（该系列还引入了SP1、SP2、SP3版本）版本相比引入了很多的创新及更新，包括提供了全新的安装器等，而SUSE Linux Enterprise High Performance Computing(HPC)还包含了应用于高性能计算机的系列组件。HPC版本还有工作负载管理器、集群监控和诸多管理软件，多个精选的MPI部署方案、一个环境模组系统，丰富的开发和跑分工具等等。SUSE公测项目和SDK项目经理Vincent Moutoussamy称SLE HPC 15是那些高性能计算机的首选，能够让用户自行挑选系统角色。
SUSE Linux Enterprise Server 15部分更新：
Changes to the installation and the module system:
Unified installer: All SUSE Linux Enterprise 15 products can be installed by the same unified installer media. For information about available modules, see Section 2.9.1, “Modules in the SLE 15 GA Product Line” .
Installation without network using Packages media: To install without network connection, all necessary packages are available on the Packages medium. This medium consists of directories with module repositories which need to be added manually as needed. RMT (Repository Mirroring Tool) and SUSE Manager provide additional options for disconnected or managed installation.
Migration from openSUSE Leap to SUSE Linux Enterprise Server: Starting with SUSE Linux Enterprise 15 GA, we support migrating from openSUSE Leap 15 to SUSE Linux Enterprise Server 15. Thus, even if you decide to start out with the free community distribution you can later easily upgrade to a distribution with enterprise-class support.
Extended package search: Use the new Zypper command zypper search-packages to search across all SUSE repositories available for your product even if they are not yet enabled. This functionality makes it easier for administrators and system architects to find the software packages needed. To do so, it leverages the SCC.
Software Development Kit: With SUSE Linux Enterprise 15, the Software Development Kit is now integrated into the products. Development packages are packaged alongside regular packages. In addition, the Development Tools module contains the tools for development.
RMT replaces SMT: SMT (Subscription Management Tool) has been removed. Instead, RMT (Repository Mirroring Tool) now allows mirroring SUSE repositories and custom repositories. You can then register systems directly with RMT. In environments with tightened security, RMT can also proxy other RMT servers. For more information, see Section 3.2.1, “SMT Has Been Replaced by RMT” .
Major updates to the software selection:
Salt: SUSE Linux Enterprise 15 can be managed via salt to help integration into up-to-date management solutions, such as SUSE Manager.
Python 3: As the first enterprise distribution, SUSE Linux Enterprise 15 GA offers full support for Python 3 development in addition to Python 2.
Directory Server: 389 Directory Server replaces OpenLDAP to provide a sustainable directory service.
