-
-* `Compat.@assume_effects setting... ex` overrides the compiler's effect modeling for the method definition `ex` on Julia versions that support this feature. Julia version without support just pass back `ex`. ([#43852]) (since Compat 4.4.0)

-
-* `isunordered(x)` returns true if `x` is value that is normally unordered, such as `NaN` or `missing` ([#35316]) (since Compat 3.31.1)
-
-* `get` accepts tuples and numbers ([#41007], [#41032]) (since Compat 3.31)
