+# v1.0.0
+
+First major release! This release is considered production-ready, and subsequent breaking changes will require bumping the major version.
+
+Also, v0 is now frozen and will not be receiving any more updates.
+
+This changelog lists the changes relative to v0.11.0.
+
+## Breaking changes
+
+- Return `(TSource Argmax, TResult Max)` from `Argmax()` instead of `(TResult Max, TSource Argmax)`; likewise for `Argmin()`
+- Capitalize property names in the returned tuple for `Enumerate()`
+- Change the behavior of `Argmin()` and `Argmax()` to match `Min()` and `Max()`. Specifically:
+    - `null` is never returned as the min or max unless all values in the input enumerable are `null` or the input enumerable's elements are of a nullable type and the enumerable is empty.
+    - If either `TSource` or `TResult` is non-nullable, the `Argmin()` and `Argmax()` of an empty enumerable will throw `InvalidArgumentException`.
+
+## New features
+
+- New `Optional.Of()` and `Optional.Flatten()` overloads for `Nullable<T>`. These both work to prevent ending up with an `Optional<Nullable<T>>`.
+- Add a `Collapse()` extension method for `Either<T, T>.` and `Result<T, T>`
+- `InvalidOperationException`s thrown from calling `Argmin()` or `Argmax()` on an empty enumerable now contain an error message.
+- Add a set of `Argmin()` and `Argmax()` overloads for numeric types and the nullable versions of those types. This parallels `Min()` and `Max()` and is needed for the null-handling behavior mentioned above. Specifically, `null` is normally considered less than any number, but we want to avoid returning it as the minimum.
+- Add a set of `Argmin()` and `Argmax()` overloads that do not take a selector function and simply return the index of the minimizing or maximizing element along with that element.
