 Swift 5.1
 ---------
 
-* [SE-0244][]:
-
-  Functions can now hide their concrete return type by declaring what protocols
-  it conforms to instead of specifying the exact return type:
-
-  ```
-  func makeMeACollection() -> some Collection {
-    return [1, 2, 3]
-  }
-  ```
-
-  Code that calls the function can use the interface of the protocol, but
-  does not have visibility into the underlying type.
-
-* [SE-0254][]:
-
-  Subscripts can now be declared `static` or (inside classes) `class`.
-
-* [SE-0252][]:
-
-  The existing `@dynamicMemberLookup` attribute has been extended with a
-  support for strongly-typed keypath implementations:
-
-  ```swift
-  @dynamicMemberLookup
-  struct Lens<T> {
-    let getter: () -> T
-    let setter: (T) -> Void
-
-    var value: T {
-      get {
-        return getter()
-      }
-      set {
-        setter(newValue)
-      }
-    }
-
-    subscript<U>(dynamicMember keyPath: WritableKeyPath<T, U>) -> Lens<U> {
-      return Lens<U>(
-          getter: { self.value[keyPath: keyPath] },
-          setter: { self.value[keyPath: keyPath] = $0 })
-    }
-  }
-  ```
-
-* [SR-8546][], [SR-9043][]:
-
-  More thorough checking has been implemented for restrictions around
-  escaping closures capturing `inout` parameters or values of noescape type.
-  While most code should not be affected, there are edge cases where
-  the Swift 5.0 compiler would accept code violating these restrictions.
-  This could result in runtime crashes or silent data corruption.
-  
-  An example of invalid code which was incorrectly accepted by the Swift 5.0
-  compiler is an `@escaping` closure calling a local function which
-  references an `inout` parameter from an outer scope:
-
-  ```swift
-  struct BadCaptureExample {
-    var escapingClosure: () -> ()
-
-    mutating func takesInOut(_ x: inout Int) {
-      func localFunction() {
-        x += 1
-      }
-
-      escapingClosure = { localFunction() }
-    }
-  }
-  ```
-
-  The compiler now correctly diagnoses the above code by pointing out that
-  the capture of `x` by `localFunction()` is invalid, since `localFunction()`
-  is referenced from an `@escaping` closure.
-
-  This also addresses certain cases where the compiler incorrectly diagnosed
-  certain code as invalid, when in fact no violation of restrictions had
-  taken place. For example,
-
-  ```swift
-  func takesNoEscape(_ fn: () -> ()) {
-    func localFunction() {
-      fn()
-    }
-
-    { localFunction() }()
-  }
-  ```
-
-* [SR-2672][]:
-
-  Conversions between tuple types are now fully implemented.
-  Previously, the following would diagnose an error:
-
-  ```swift
-  let values: (Int, Int) = (10, 15)
-  let converted: (Int?, Any) = values
-
-* [SE-0242][]:
-
-  The memberwise initializer for structures now provide default values for variables that hold default expressions.
-
-  ```swift
-  struct Dog {
-    var name = "Generic dog name"
-    var age = 0
-
-    // The synthesized memberwise initializer
-    init(name: String = "Generic dog name", age: Int = 0)
-  }
-
-  let sparky = Dog(name: "Sparky") // Dog(name: "Sparky", age: 0)
-  ```
-
-* [SE-0068][]:
-
-  It is now possible to use `Self` to refer to the innermost nominal
-  type inside struct, enum and class declarations. For example, the
-  two method declarations inside this struct are equivalent:
-  
-  ```swift
-  struct Box<Value> {
-    func transform1() -> Self { return self }
-    func transform2() -> Box<Value> { return self }
-  }
-  ```
-
-  In classes, `Self` is the dynamic type of the `self` value, as before.
-  Existing restrictions on `Self` in declaration types still apply;
-  that is, `Self` can only appear as the return type of a method.
-  However, `Self` can now be used inside the body of a method
-  without limitation.
-
-* [SR-7799][]:
-
-  Enum cases can now be matched against an optional enum without
-  requiring a '?' at the end of the pattern.
-
-  ```swift
-  enum Foo { case zero, one }
-
-  let foo: Foo? = .zero
-
-  switch foo {
-    case .zero: break
-    case .one: break
-    case .none: break
-  }
-  ```
-
-* `weak` and `unowned` stored properties no longer inhibit the
-   automatic synthesis of `Equatable` or `Hashable` conformance.
-
-* [SR-2688][]:
-
-  An `@autoclosure` parameter can now be declared with a typealias type.
-
-  ```swift
-  class Foo {
-    typealias FooClosure = () -> String
-    func fooFunction(closure: @autoclosure FooClosure) {}
-  }
-  ```
-
-* [SR-7601][]:
-
-  Methods declared `@objc` inside a class can now return `Self`:
-
-  ```swift
-  class MyClass : NSObject {
-    @objc func clone() -> Self { return self }
-  }
-  ```
-
-* [SR-2176][]:
-
-  Assigning '.none' to an optional enum which also has a 'none' case
-  or comparing such an enum with '.none' will now warn. Such expressions
-  create an ambiguity because the compiler chooses Optional.none
-  over Foo.none.
-
-  ```swift
-  enum Foo { case none }
-
-  // Assigned Optional.none instead of Foo.none
-  let foo: Foo? = .none
-  // Comparing with Optional.none instead of Foo.none
-  let isEqual = foo == .none
-  ```
-
-  The compiler will provide a warning along with a fix-it to
-  replace '.none' with 'Optional.none' or 'Foo.none' to resolve
-  the ambiguity.
-
 * Key path expressions can now include references to tuple elements.
 
-* Single-parameter functions accepting values of type `Any` are no
-  longer preferred over other functions.
-
-  ```swift
-  func foo(_: Any) { print("Any") }
-  func foo<T>(_: T) { print("T") }
-  foo(0) // prints "Any" in Swift < 5.1, "T" in Swift 5.1
-  ```
-
-* [SE-0245][]:
-
-  `Array` and `ContiguousArray` now have `init(unsafeUninitializedCapacity:initializingWith:)`,
-  which provides access to the array's uninitialized storage.
