Notes de version

January 2018

• The VirtualBox and VMWare releases of the HDF sandox had their OS-level packages updated, including a version update of Docker from 17.09 to 17.12.
• A patch was applied to the released VMs which updated them to the 4.14.14-1 kernel to address the Meltdown/Spectre vulnerability.
• The VirtualBox and VMWare releases were reduced to a total size of about 10.4 GB. As a result, a loading splash page will show up on first boot while the sandbox is decompressed and set up.
• Minor splash page typo fixes.
