 ## [Unreleased]
 
+### Changed
+
+- **`PackageValidationBaselineVersion` moved to `1.0.1`**, now that 1.0.1 is published and restorable. From here an accidental break in the public surface fails the build against the first stable release rather than against `0.3.1`, so a break is a 2.0.0 rather than a judgement call. There is no 1.0.0 to baseline against — it was never published.
