# waldo 0.4.0
* Atomic S3 classes with format methods now use those methods when
displaying comparisons (#98). If the printed representation is the
same, they fallback to displaying the underlying data.
* Rowwise data frame comparisons are now much much faster (#116),
and respect the `max_diffs` argument (@krlmlr, #110).
* Unnamed environments now compare by value, not by reference (i.e. if
two environments contain the same values, they compare the same, even
if they're different environments) (#127). Environments that contain
self-references are handled correctly (#117). Differences between pairs
of environments are only ever reported once.
* In the unlikely event that you have bare CHARSXP objects, waldo now
handles them (#121).
* S4 objects are labelled with their class, not all superclasses (#125).
* `compare_proxy()` ignores the `"index"` attribute for data tables
(@krlmlr, #107), and works again for `RProtoBuf` objects
(@MichaelChirico, #119)
* Infinite values can be compared with a tolerance (@dmurdoch, #122).
