Platform and Infrastructure

• This release includes code infrastructure changes that improve the effectiveness and scalability of the core JUNOS code.

Software Installation and Upgrade

• Previously, upgrading images on J-series routers with a 256-MB compact flash from Release 8.5 onward involved removing unwanted files in the images and removing the Swap Partition. Now, the software accomplishes the upgrade efficiently by using mdimage to take another snapshot of the compact flash, install the image, and restore configurations.
