What's new in version 18.04 LTS (Bionic Beaver)
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.
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.
In Ubuntu 18.04 LTS, gcc is now set to default to compile applications as position independent executables (PIE) as well as with immediate binding, to make more effective use of Address Space Layout Randomization (ASLR). All packages in main have been rebuilt to take advantage of this, with a few exceptions.
Improved UEFI Secure Boot handling for the use of third-party modules.
Teaming support with libteam is available in NetworkManager.Update your desktop app for new features.
