-Copying from `const(void)[]` to `void[]` is disallowed with `-preview=fixImmutableConv`
-
-If `const(void)[]` data contains tail `const` pointers, copying to `void[]`
-can subsequently violate `const` data:
----
-void f(int*[] a, const int*[] b)
-{
-    void[] va = a;
-    const void[] vb = b;
-    va[] = vb[]; // fills `a` with pointers to const

-Copying `vb` data to `va` is no longer allowed with the
-`-preview=fixImmutableConv` switch.

-Import expressions are now treated as hex strings
-
-While [Import expressions](https://dlang.org/spec/expression.html#import_expressions) are typed as `string`, they are also used to embed binary files.
-By treating them the same as hex strings, they will implicitly convert to arrays of integral types other than `char`.
-
----
-// Formerly, a cast was required:
-immutable ubyte[] iconImg = cast(immutable ubyte[]) import("icon.png");
-
-// Now, it implicitly converts to integral arrays:
-immutable ubyte[] iconImg = import("icon.png");

-New trait isCOMClass to detect if a type is a COM class
-
-A COM class inherits from a possibly user defined interface called ``IUnknown``.
-To detect this during compilation use the trait ``__traits(isCOMClass, Type)``.
-Or for during runtime use the ``TypeInfo_Class`` flag.

-`bool` values other than 0 or 1 are not `@safe`
-
-The spec [was updated](https://dlang.org/spec/type.html#bool)
-(for 2.109) so that only 0 and 1 are
-[safe values](https://dlang.org/spec/function.html#safe-values)
-for `bool`. This means that reading a `bool` value whose underlying byte representation
-has other bits set is implementation-defined and should be avoided.
-Consequently the following are deprecated in `@safe` code:
-
-* `void` initialization of booleans (since 2.109)
-* Reading a `bool` field from a union (since 2.109)
-* Runtime casting a dynamic array to a `bool` dynamic array type
-* Runtime casting a `bool` dynamic array to a tail mutable dynamic array type
-* Casting a pointer to a `bool` pointer type
-* Casting a `bool` pointer to a tail mutable pointer type
