Just one week after RHEL 7.3 release Oracle has announced the general availability of Oracle Linux 7.3 as well.
There is lot of improvements and features but the most notable fact about OL 7.3 is that comes with Unbreakable Enterprise Kernel 4 (UEK4) and older UEK3 is not shipped in distribution while it still supported. Starting with 7.3 version OL supports UEFI Secure Boot. The bad news is that kpatch package has been removed from the distribution.
For more information about new version see the release notes at: https://docs.oracle.com/cd/E52668_01/E79987/html/index.html
You can download the ISOs either from MOS site or Oracle Software Delivery Cloud (aka edelivery.oracle.com).
