 # bench (development version)
 
+* `bench::mark()` and `bench::workout()` no longer support unquote
+  and splice operators. This fixes inconsistencies in performance
+  results with functions like `rlang::list2()` (#61).
+
 * `autoplot.bench_mark()` again supports factor levels for `expression`, as intended (#82)
