   - **Bug Fix:** Validates the `with_boundaries` bucket boundaries used in
     Histograms. The boundaries provided by the user must not contain `f64::NAN`,
-    `f64::INFINITY`, `f64::NEG_INFINITY` and must be sorted in strictly
+    `f64::INFINITY` or `f64::NEG_INFINITY` and must be sorted in strictly
     increasing order, and contain no duplicates. Instruments will not record
     measurements if the boundaries are invalid.
