| 35 | +$(P |
| 36 | +If `const(void)[]` data contains tail `const` pointers, copying to `void[]` |
| 37 | +can subsequently violate `const` data: |

| 46 | +} |
| 47 | +--- |
| 48 | +$(P |
| 49 | +Copying `vb` data to `va` is no longer allowed with the |

| 56 | +$(P |
| 57 | +While [Import expressions](https://dlang.org/spec/expression.html#import_expressions) are typed as `string`, they are also used to embed binary files. |
| 58 | +By treating them the same as hex strings, they will implicitly convert to arrays of integral types other than `char`. |

| 62 | +// Formerly, a cast was required: |
| 63 | +immutable ubyte[] iconImg = cast(immutable ubyte[]) import("icon.png"); |
| 64 | + |

| 71 | +$(CHANGELOG_SOURCE_FILE dmd, changelog/dmd.unsafe-boolean-values.dd) |
| 72 | +$(P |
| 73 | +The spec [was updated](https://dlang.org/spec/type.html#bool) |
| 74 | +(for 2.109) so that only 0 and 1 are |
| 75 | +[safe values](https://dlang.org/spec/function.html#safe-values) |
| 76 | +for `bool`. This means that reading a `bool` value whose underlying byte representation |
| 77 | +has other bits set is implementation-defined and should be avoided. |
| 78 | +Consequently the following are deprecated in `@safe` code: |
| 79 | +) |
| 80 | + |
| 81 | +$(P |
| 82 | +* `void` initialization of booleans (since 2.109) |
| 83 | +* Reading a `bool` field from a union (since 2.109) |
| 84 | +* Runtime casting a dynamic array to a `bool` dynamic array type |
| 85 | +* Runtime casting a `bool` dynamic array to a tail mutable dynamic array type |
| 86 | +* Casting a pointer to a `bool` pointer type |
| 87 | +* Casting a `bool` pointer to a tail mutable pointer type |

| 97 | +$(CHANGELOG_SOURCE_FILE dub, changelog/selections_from_parent_dir.dd) |
| 98 | +$(P |
| 99 | +In case the root package directory doesn't contain a `dub.selections.json` |
| 100 | +file, dub now looks in parent directories too and potentially uses the |
| 101 | +first (deepest) one it finds - if and only if that JSON file contains an |
| 102 | +optional new `"inheritable": true` flag. |
| 103 | +) |
| 104 | + |
| 105 | +$(P |
| 106 | +This allows using a 'central' `dub.selections.json` file for a repository |
| 107 | +containing multiple dub projects, making it automatically apply to all |
| 108 | +builds in that source tree if located in the repository root directory |
| 109 | +(unless a local `dub.selections.json` overrides it). |
| 110 | +) |
| 111 | + |
| 112 | +$(P |
| 113 | +Such an inherited selections file is never mutated when running dub for a |
| 114 | +nested project, i.e., changes are always saved to a *local* |
| 115 | +`dub.selections.json` file. E.g., when running `dub upgrade` for a nested |
| 116 | +project. |
