================= buildstream 1.1.2 ================= o New ref-storage option allows one to store source refs, such as git shas, in one central project.refs file instead of inline with the source declarations. o Deprecated `--track-save` optionality in `bst build`, this does not make sense to support now that we have project.refs. o Added the `sandbox` configuration option which can be used in `project.conf` and elements, to control the user ID and group ID used in build sandboxes. o Added new `deb` source implementation, for staging of downloaded deb package files.
