- updated to version 0.19.0 with follwoinig changes:
* Spack's traditional package preferences are soft, but we've added hard
requriements to packages.yaml and spack.yaml
* spack install in an environment will no longer add to the specs: list; you'll
need to either use spack add or spack install --add .
* spack uninstall will not remove from your environment's specs:
list; you'll need to use spack remove or spack uninstall --remove.
* concretizer:unify:true is now the default mode for new environments
* include environment configuration from URLs
* An increasing number of packages in the ecosystem need the ability to
support multiple build systems
* package ++variant:
enabled variant that will be propagated to dependencies
* git. prefix to specify git tags or branches as versions. All of these are
valid git versions in
* spack ci generate --tests will generate a .gitlab-ci.yml file that not only
does builds but also runs tests for built packages
* spack test run --explicit will only run tests for packages that are
explicitly installed, instead of all packages.
* You can add a new shared_linking option to config.yaml to make Spack embed absolute paths
to needed shared libraries in ELF executables and shared libraries on Linux
* spack spec prints dependencies more legibly. Dependencies in the output now
appear at the earliest level of indentation possible (#33406)
* You can override package.py attributes like url, directly in packages.yaml
* There are a number of new architecture-related format strings you can use
in Spack configuration files to specify paths
- Improvement from v0.18.0
* spack install --reuse was introduced in v0.17.0, and --reuse is now the
default concretization mode. Spack will try hard to resolve dependencies
using installed packages or binaries
