This is a 16 byte md5 signature of the fully qualified name of the class.
45+
It is used to compare two classes for equality, rather than comparing the
46+
pointers with a fallback to doing a string compare on the name, which can
47+
be rather slow.

The result is both druntime and phobos will need to be recompiled to be

compatible with this change. Any libraries will need to be recompiled

as well.

Default arguments for functions can contain the keywords `__FILE__`,
61+
`__FILE_FULL_PATH__`, `__MODULE__`, `__LINE__`, `__FUNCTION__`
62+
and `__PRETTY_FUNCTION__`. They are now evaluated at the source location
63+
of the calling function in more complex expressions as long as used in
64+
an initializer, directly or not. Previously they had to be used directly
65+
in the initializer to be evaluated at the call site. Here are some
66+
examples, where more complex initializers are now evaluated at the
67+
call site:

106+
$(CHANGELOG_SOURCE_FILE dmd, changelog/dmd.hexstring-cast.dd)
107+
$(P
108+
Hex strings are the most efficient way to embed binary data into source files.
109+
However, they couldn't easily be used to initialize a `short[]`, `int[]` or `long[]` because re-interpret casting arrays is not allowed during CTFE.
110+
Now, hex strings can be cast to integer arrays with element types larger than `byte`.
111+
A big endian byte order is assumed, consistent with how integer literals are written.
112+

121+
Character postfixes can now also be used for integers of size 2 or 4:
122+
)
123+
---
124+
immutable ushort[] f = x"80 3F"w;
125+
static assert(f[0] == 0x803F);

static assert(f[0] == 0x803FFF);

130+
131+
$(P
132+
Formerly, they would pad each byte with 1 or 3 zeros, which did not serve a purpose (See [Issue 24363](https://issues.dlang.org/show_bug.cgi?id=24363)).
133+
)
134+
135+
$(P
136+
If the string's byte length is not a multiple of the target element size, it is an error:
137+
)
138+
139+

$(LI $(LNAME2 dmd.ies,Add support for Interpolated Expression Sequences)
145+
$(CHANGELOG_SOURCE_FILE dmd, changelog/dmd.ies.dd)
146+
$(P
147+
Interpolated Expression Sequences are a way to implement things like string interpolation in library code. Three forms of literals are added:
148+
)
149+
150+
```
151+
i"Content $(a + 4)"
152+
i`Content $(a + 4)`
153+
iq{Content $(a + 4)}
154+
```
155+
156+
$(P
157+
all provide the same thing: a tuple that can be passed to other functions, like `writeln` from `std.stdio` and `text` from `std.conv`:
158+
)
159+
160+
```
161+
int a = 6;
162+
writeln(i"Content $(a + 4)"); // prints "Content 10"
163+
```
164+
165+
$(P
166+
You can also pass them to other functions which understand the types in the new `core.interpolation` module. Numerous examples can be found documentation of that module or in this repository: https://github.com/adamdruppe/interpolation-examples/
167+

$(BUGSTITLE_TEXT_BODY Library changes,
174+
175+
$(LI $(LNAME2 range_predicate_element,`isForwardRange`, `isBidirectionalRange`, and `isRandomAccessRange` now take an optional element type)
176+
$(CHANGELOG_SOURCE_FILE phobos, changelog/range_predicate_element.dd)
177+
$(P
178+
In Phobos 2.106, an optional second template parameter was added to
179+
`isInputRange` to enable conveniently checking a range's element type. Now, the
180+
same parameter has been added to `isForwardRange`, `isBidirectionalRange`, and
181+
`isRandomAccessRange`.
182+
)
183+
184+
$(P
185+
As before, if a second type argument is passed to one of these templates, the
186+
range's element type is checked to see if it is
187+
$(DDSUBLINK spec/const3, implicit_qualifier_conversions, qualifier-convertible)
188+
to the given type, and this additional check must pass in order for the
189+
template to evaluate to `true`.
190+
)
191+
192+
$(P
193+
Examples:
194+
)
195+
---
196+
// exact match
197+
static assert( isForwardRange!(int[], int));
198+
199+
// match with qualifier conversion
200+
static assert( isBidirectionalRange!(int[], const(int));
201+
202+
// not a match
203+
static assert(!isRandomAccessRange!(int[], string));

$(LI $(LNAME2 upgrade-unicode,std.uni has been upgraded from Unicode 15.0.0 to 15.1.0)
208+
$(CHANGELOG_SOURCE_FILE phobos, changelog/upgrade-unicode.dd)
209+
$(P
210+
This Unicode update was released September 12, 2023.
211+
See: https://www.unicode.org/versions/Unicode15.1.0/
212+
)
213+
214+
```
215+
import std;
216+
217+
void main()
218+
{
219+
const alphaCount = iota(0, dchar.max).filter!(std.uni.isAlpha).walkLength;
220+
writeln(alphaCount);
221+
// formerly: 137765
222+
// now: 138387
223+
// 622 new dchars return true for `isAlpha`
224+
}
225+
```
226+
227+
$(P
228+
The internal unicode tables (std/internal/unicode_tables.d) have also been changed to use hex strings instead of array literals, which makes them faster to import.
229+
The exact speed up depends on your computer and D compiler, but it likely cuts between 30 and 100 milliseconds if you compile something which imports `std.string` or `std.uni`.

$(BUGSTITLE_TEXT_BODY Dub changes,

238+
$(LI $(LNAME2 dub-fetch,The fetch command now supports multiple arguments, recursive fetch, and is project-aware)
239+
$(CHANGELOG_SOURCE_FILE dub, changelog/dub-fetch.dd)
240+
$(P
241+
Previously, `dub fetch` could only fetch a single package,
242+
and was working independently of the working directory.
243+
)
244+
245+
$(P
246+
With this release, support for multiple packages have
247+
been added, such that the following is now possible:
248+
)
249+
---
250+
$ dub fetch vibe-d@0.9.0 vibe-d@0.9.1 vibe-d@0.9.2
251+
---
252+
253+
$(P
254+
When called with no argument, `dub fetch` used to error out.
255+
However, it will now attempt to fetch dependencies for the
256+
current project, if any exists.
257+
)
258+
259+
$(P
260+
Finally, when fetching a package, it might be useful to fetch
261+
all its dependencies. This is done automatically for projects,
262+
and can now be done for direct fetch as well:
263+
)
264+

265+
$ dub fetch --recursive vibe-d@0.9.0 vibe-d@0.9.1
