Linux kernel 4.15
Ubuntu 18.04 ships with a v4.15 based Linux kernel, enabling the latest hardware and peripherals available from IBM, Intel, and others. The 18.04 kernel delivers new features inherited from upstream, including:
- CPU controller for the cgroup v2 interface
- AMD secure memory encryption support
- The latest MD driver with software RAID enhancements
- Improved power management for systems with SATA Link Power Management
We also see notable Ubuntu specific achievements with:
- Linux security module stacking support
- Support for signing of POWER host and NV kernels
- Backport improved support for IBM and Intel hardware from Linux 4.16
As of 18.04 release, OpenJDK 10 is the default JRE/JDK. Once OpenJDK 11 reaches GA in September 2018, it will become the default in 18.04.
OpenJDK 8 has moved to universe and will remain available there for the life of 18.04, to provide migration time for packages, custom applications, or scripts that can’t be build with OpenJDK 10 or 11. OpenJDK 8 will be updated in 18.04 until Ubuntu 16.04 LTS reaches EOL in April 2021.
