To be released
This changelog has been automatically generated from all commits in master since the last release.
- The full-text messages are assembled from the changelog/ directories of the respective repositories: dmd, druntime, phobos, tools, dlang.org, installer, and dub.
- See the DLang-Bot documentation for details on referencing Bugzilla. The DAutoTest PR preview doesn't include the Bugzilla changelog.

Compiler changes
List of all upcoming bug fixes and enhancements in D 2.111.0.
Compiler changes
- 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 *a[0] = 0; // const data mutated }
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 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");
- bool values other than 0 or 1 are not @safe
The spec was updated (for 2.109) so that only 0 and 1 are 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
Dub changes
- dub.selections.json files are now looked up in parent directories too
In case the root package directory doesn't contain a dub.selections.json file, dub now looks in parent directories too and potentially uses the first (deepest) one it finds - if and only if that JSON file contains an optional new "inheritable": true flag.
This allows using a 'central' dub.selections.json file for a repository containing multiple dub projects, making it automatically apply to all builds in that source tree if located in the repository root directory (unless a local dub.selections.json overrides it).
Such an inherited selections file is never mutated when running dub for a nested project, i.e., changes are always saved to a local dub.selections.json file. E.g., when running dub upgrade for a nested project.
