Changed defaults / behaviours

⚠️ Go module was renamed from github.com/sylabs/singularity to github.com/hpcng/singularity

New features / functionalities

  • A new overlay command allows creation and addition of writable overlays.
  • Administrators can allow named users/groups to use specific CNI network configurations. Managed by directives in singularity.conf.
  • The build command now honors --nv, --rocm, and --bind flags, permitting builds that require GPU access or files bound in from the host.
  • A library service hostname can be specified as the first component of a library:// URL.
  • Singularity is now relocatable for unprivileged installations only.

Bug Fixes

  • Respect http proxy server environment variables in key operations.
  • When pushing SIF images to oras:// endpoints, work around Harbor & GitLab failure to accept the SifConfigMediaType.
  • Avoid a setfsuid compilation warning on some gcc versions.
  • Fix a crash when silent/quiet log levels used on pulls from shub:// and http(s):// URIs.
  • Wait for dm device to appear when mounting an encrypted container rootfs.
  • Accommodate ppc64le pageSize in TestCgroups and disable -race.
  • Fix Debian packaging.

Testing / Development

Testing changes are not generally itemized. However, developers and contributors should note that this release has modified the behavior of make test for ease of use:

  • make test runs limited unit and integration tests that will not require docker hub credentials.
  • make testall runs the full unit/integration/e2e test suite that requires docker credentials to be set with E2E_DOCKER_USERNAME and E2E_DOCKER_PASSWORD environment variables.
