[EDIT: this release is strictly identical to 1.12.0; the pkg fix is actually not included. We keep it to avoid messing with package managers relying on release events, but you should use 1.12.2 instead for the pkg fix]
Fix the generated package-enabled binary artifacts (with -pkg). They didn't include the package management experimental feature as initially advertised in 1.12.0 due to an error in the build workflow.
