See #12989 + +2. **Virtual package configuration** Virtual packages are allowed in +packages.yaml configuration. This allows users to specify a virtual +package as non-buildable without needing to specify for each +implementation. See #14934 + +3. **New config subcommands** This release adds `spack config add` and +`spack config remove` commands to add to and remove from yaml +configuration files from the CLI. See #13920 + +4. **Environment activation** Anonymous environments are **no longer** +automatically activated in the current working directory. To activate +an environment from a `spack.yaml` file in the current directory, use +the `spack env activate .` command. This removes a concern that users +were too easily polluting their anonymous environments with accidental +installations. See #17258 + +5. **Apple clang compiler** The clang compiler and the apple-clang +compiler are now separate compilers in Spack. This allows Spack to +improve support for the apple-clang compiler. See #17110 + +6. **Finding external packages** Spack packages can now support an API +for finding external installations. This allows the `spack external +find` command to automatically add installations of those packages to +the user's configuration.
