- updated to version 0.17.0
(Upstream feature/bug references (<ID>) are relative to
https://github.com/spack/spack/issues/<ID>).
* New concretizer is now default
The new concretizer introduced as an experimental feature in v0.16.0
is now the default (#25502). The new concretizer is based on the
clingo logic programming system,
and it enables us to do much higher quality and faster dependency solving
The old concretizer is still available via the concretizer: original
setting, but it is deprecated and will be removed in v0.18.0.
* Binary Bootstrapping
To make it easier to use the new concretizer and binary packages,
Spack now bootstraps clingo and GnuPG from public binaries. If it
is not able to bootstrap them from binaries, it installs them from
source code. With these changes, you should still be able to clone Spack
and start using it almost immediately.
* Reuse existing packages (experimental)
The most wanted feature from our
2020 user survey and
the most wanted Spack feature of all time (#25310). spack install,
spack spec, and spack concretize now have a --reuse option, which
causes Spack to minimize the number of rebuilds it does. The --reuse
option will try to find existing installations and binary packages locally
and in registered mirrors, and will prefer to use them over building new
versions. This will allow users to build from source far less than in
prior versions of Spack. This feature will continue to be improved, with
configuration options and better CLI expected in v0.17.1. It will become
the default concretization mode in v0.18.0.
* Better error messages
We have improved the error messages generated by the new concretizer by
