The Oracle Linux 7.0 operating system has been released by Oracle and brings numerous new features and changes, like Unbreakable Enterprise Kernel Release 3 and a new default file system.The Oracle developers have gone through a couple of Release Candidates for this new build of the distribution and now the final version has arrived. As expected, it's packed with a ton of modifications, which include the new XFS as the default operating system, Btrfs as an alternative, Linux Containers (LXC), DTrace, Ksplice, Xen enhancements, and the Unbreakable Enterprise Kernel Release 3.
As opposed to the more popular EXT4 file system, XFS has one major advantage. It allows users to have 500 TB for the file system size, which is ten times more than what you would get with EXT4. The only drawback is that it only allows for 16 TB maximum file size.
The distribution features two supported kernels. One is the Red Hat Compatible Kernel (RHCK), based on mainline Linux version 3.10, and the second one is their own version, which is called the Unbreakable Enterprise Kernel Release 3 (UEK R3), and starting with 3.8.13 it's based on the mainline Linux version 3.8. You might remember that Linux Kernel 3.8.x has already reached end of life, but it looks like Oracle is maintaining its own branch.
“Available for download from Oracle Software Delivery Cloud, Oracle Linux 7 is free to download and distribute. All bug fixes and security errata are published to Oracle's public yum servers, allowing customers to install the same code across all their deployments, with or without a subscription, and creating a simple migration path from free to paid.

“This release builds on Oracle's approach to providing support for emerging technologies, such as OpenStack, while delivering the latest Linux innovations, tools, and features customers and partners need to deliver enterprise-grade solutions for the modern data center,” reads the official announcement.
