45+
$(P
46+
C code normally relies on `#include <assert.h>` to add support for assert's. D has them builtin to the
47+
language, which is much more convenient and does not rely on a preprocessor. This extension adds

__check(assign-expression)

55+
as an expression to ImportC. The compiler switch -checkaction=C gives it the same behavior
56+
as C's assert macro. If the compiler switch -release is thrown, the `__check`'s are ignored.
57+
The `__check` expressions are handy for writing C programs that are free of reliance on `#include`.
58+
)
59+
60+
$(P

`__assert` is not used due to conflicts with some C .h files.

$(CHANGELOG_SOURCE_FILE dmd, changelog/dmd.deprecate-alias-this-for-classes.dd)
67+
$(P
68+
Using `alias this` for classes has not been clearly specified and the lookup rules in such circumstances are not defined. As a consequence, various failures or crashes may appear when `alias this` is used in conjunction with classes. Starting with this release, `alias this` for classes is being deprecated. As an alternative, getter/setter methods may be used to replace the `alias this`. This can be generically handled by:

80+
Deprecation warnings for [DIP25](http://dlang.org/dips/25) violations have been enabled since 2.092.
81+
Starting with this release, it will report errors, unless the `-revert=dip25` switch is used.

Using the switch (or its short version `-dip25`) is now deprecated.

108+
$(CHANGELOG_SOURCE_FILE dmd, changelog/dmd.get-is-virtual-function.dd)
109+
$(P
110+
Up until this release, D had both `traits(isVirtualFunction)` and `traits(isVirtualMethod)`
111+
(and their coressponding `traits(get...)` counterpart). The differenrcte between the two is
112+
that `isVirtualFunction` returns true for `final` methods that do not override anything. This
113+
is in contradiction with the D spec which states that `final` functions that do not override
114+
other functions cannot be virtual. `isVirtualMethod` correctly returns `false` in that case.
115+
)
116+
117+
$(P
118+
Starting with this release, both `traits(isVirtualFunction)` and `traits(getVirtualFunctions)`
119+
are deprecated. If the behavior of `traits(isVirtualFunction)` is desired, it can be achieved by
120+
`traits(isVirtualMethod, f) || (traits(isFinalFunction, f) && !traits(isOverrideFunction, f))`.

The previous `automatic`, `on`, `off` values are still supported, but

undocumented, because they are used in almost no other program like this. For
