Spack packages v2026.03.0
The 2026.03.0 release of the spack packages is released out of phase from
the Spack tool release. This release is meant to bring new packages and
package version updates and deprecations that are not made available via
backports to previous releases.
Spack version compatibility
This release continues to use the v2.2 Package API. This is the Package API
version used by the Spack v1.0.0 release. Any Spack version 1.0.0 or newer
is compatible with this release of the packages repo.
This release was tested against Spack v1.2.0.dev0 (96cae55)
and the environments used to generate the binary caches use new features
that will be part of the Spack 1.2 release. The binary caches themselves are
compatible with any Spack v1.0.0 or newer (any Spack that supports the v3
URL build cache layout), but the environments used to generate them
cannot be reconcretized with any existing Spack release, and require the
develop branch.
See the Package API
Documentation
for full details on package versioning and compatibility.
Package statistics
There are now 8752 packages in the spack-packages builtin repo. This
is up from 8615 in the previous release.
New and removed packages
This release contains a number of deprecations to address CVEs in a number
of projects, notably those related to AI stacks. These deprecated versions
will be removed in the following release.
In addition to new deprecations, all package versions deprecated prior to
the v2025.11.0 release have been removed with a few exceptions.
| Package | Reason |
|---|---|
| VTK | 8.2 for VisIt compatibility |
| Flecsi | maintainer request (#3573) |
| Fenics UFL | Older versions needed to continue building other Fenics libraries |
