Spack packages v2026.06.0
The v2026.06.0 release of the spack packages is released along with version 1.2 of
the Spack tool. This release brings 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 introduced 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 (63943396d634faa92cb59474df3558ec9b9b2425).
The stack environments used to generate the binary caches use new features
that are 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).
See the Package API
Documentation
for full details on package versioning and compatibility.
Package statistics
There are now 8917 packages in the spack-packages builtin repo. This
is up from 8752 in the previous release.
New and removed packages
This release contains a number of deprecations to address CVEs in a number
of projects.
In addition to new deprecations, all package versions deprecated prior to
the v2026.03 release have been removed with a few exceptions.
