## [Unreleased]

## [1.4.0] - 2026-05-19

### Added

- Midpoint-based `mean()` on `CumulativeROHistogram` / `CumulativeROHistogram32`
— the mean of all observations, estimated from bucket midpoints, computed
once at construction time across `from_parts`, `From<&Histogram>`, and
`From<&SparseHistogram>`. Returns `None` for an empty histogram.

### Changed

- `CumulativeROHistogram` / `CumulativeROHistogram32` no longer implement `Eq`
(they now store an `f64` mean); `PartialEq` is retained. The borrowed
`*Ref` view types are unaffected.
