$(LI $(LNAME2 add_traits_isCopyable,Add new builtin `__traits(isCopyable, T)` for some type `T`)
51+
$(CHANGELOG_SOURCE_FILE dmd, changelog/add_traits_isCopyable.dd)
52+
$(P
53+
Changing Phobos' `std.traits.isCopyable` to make use of this new builtin trait
54+
will reduce memory usage and, in turn, improve the performance of the compiler
55+
checking whether a type is copyable or not.

$(LI $(LNAME2 check_interface_implementations,Properly check interface implementations)
60+
$(CHANGELOG_SOURCE_FILE dmd, changelog/check_interface_implementations.dd)
61+
$(P
62+
In previous releases the check to verify that a class implements all methods of
63+
the interfaces it implements was performed late in the compilation phase. This
64+
caused the check to not be performed when code generation was skipped
65+
(compiling with the `-o-` flag).
66+
)
67+
68+
$(P
69+
In this release the check has been moved to an earlier phase of the compilation,
70+
causing errors to be reported even when the `-o-` flag is used. This can cause
71+
some breakage if a piece of code has only been compiled with the `-o-` flag.
72+
)
73+
74+
$(P
75+
The compiler will now properly report an error for the following code when the
76+
`-o-` flag is used:
77+
)
78+
79+
```
80+
interface Foo
81+
{
82+
void foo();
83+
}
84+
85+

$(LI $(LNAME2 shared-init,Allow initialization of shared variables.)

109+
$(CHANGELOG_SOURCE_FILE dmd, changelog/vtemplates.dd)
110+
$(P
111+
Template instantiations can consume lots of time and memory.
112+
By passing the -vtemplates switch to the compiler,
113+
the compiler will collect and print statistics about template usage
114+
in the code being compiled.

For each template that was instantiated, a list of how many

205+
$(CHANGELOG_SOURCE_FILE installer, changelog/install_sh_windows.dd)
206+
$(P
207+
The official D version manager ($(LINK2 https://dlang.org/install.sh, install.sh),
208+
documented at $(LINK2 https://dlang.org/install.html, dlang.org/install.html))
209+
used to require a POSIX environment. On Windows, prior to this release, this
210+
meant running the script and the compilers that it installed from within a
211+
POSIX terminal emulator as provided by MSYS2 or Cygwin. With this release it is
212+
now possible to install and activate compilers from the Windows command prompt
213+
directly.
214+
)
215+
216+
$(P

Assuming an MSYS2 installation is present in `C:\msys64`, necessary decompression

tools can be installed from the Windows command prompt:

-------
221+
C:\msys64\usr\bin\pacman.exe --sync unzip p7zip
222+
-------
223+
224+
$(P
225+
The following will invoke the script directly from dlang.org and install the
226+
latest dmd compiler in the `%USERPROFILE%\dlang` folder:
227+
)
228+
-------
229+
C:\msys64\usr\bin\curl.exe https://dlang.org/install.sh | \msys64\usr\bin\bash.exe -s
230+
-------
231+
$(P
232+
This process will end with a message showing the location of `activate.bat`,
233+
which can be used to add the installed compiler to your `PATH`.
234+
)
235+
236+
$(P
237+
The script itself will also be installed locally. This will show you its other
238+
uses:

260+
$(P
261+
The code from the runDubCommandLine was moved to some other structs. The new
262+
CommandLineHandler structure takes care of the CLI state and commands, which
263+
allows DUB commands to be extended in other projects.

267+
The CommandArgs class now has new `hasAppArgs` and `appArgs` methods which

allows you to get the app arguments. In addition, the `extractAllRemainingArgs`
269+
method will return all unused arguments and the app arguments.
