Vulnerability Insight:
Singularity was updated to version 2.6.0,
bringing features, bugfixes and security fixes.

Security issues fixed:

- CVE-2018-12021: Fixed access control on systems supporting overlay file
system (boo#1100333).

Highlights of 2.6.0:

- Allow admin to specify a non-standard location for mksquashfs binary at
build time with '--with-mksquashfs' option.

- '--nv' can be made default with all action commands in singularity.conf

- '--nv' can be controlled by env vars '$SINGULARITY_NV' and
'$SINGULARITY_NV_OFF'

- Restore shim init process for proper signal handling and child reaping
when container is initiated in its own PID namespace

- Add '-i' option to image.create to specify the inode ratio.

- Bind '/dev/nvidia*' into the container when the '--nv' flag is used in
conjunction with the '--contain' flag

- Add '--no-home' option to not mount user $HOME if it is not the $CWD and
'mount home = yes' is set.

- Added support for OAUTH2 Docker registries like Azure Container Registry

Highlights of 2.5.2:

- a new `build` command was added to replace `create` + `bootstrap`

- default image format is squashfs, eliminating the need to specify a size

- a `localimage` can be used as a build base, including ext3, sandbox, and
other squashfs images

- singularity hub can now be used as a base with the uri

- Restore docker-extract aufs whiteout handling that implements correct
extraction of docker container layers.

Bug fixes:

- Fix 404 when using Arch Linux bootstrap

- Fix environment variables clearing while starting instances

- several more bug fixes, see CHANGELOG.md for details
