$(BUGSTITLE Compiler Changes,

$(LI $(LNAME2 objective-c-support, Basic support for Objective-C.)

    $(P Basic support for Objective-C classes, interfaces and instance methods.
        This is implemented by adding a new linkage attribute, Objective-C, and
        a compiler recognized UDA, @selector. The linkage attribute is to be
        used on a class or interface. The UDA is attached to a method.
    )
)

$(LI $(LNAME2 property-switch-deprecated, The $(TT -property) switch has
    been deprecated.)

    $(P The $(TT -property) switch used to disallow calling non-properties
        without parentheses. The switch has not been used to build Phobos for
        some time now. So naturally, code that's incompatible with
        $(TT -property) has found its way in. This means, the switch has
        effectively not been supported by D at large.
    )

    $(P Since the behaviour of the $(TT -property) switch was not well-liked,
        it's been deprecated and made to have no effect when used.
    )
)

)

$(BUGSTITLE Library Changes,

$(LI $(LNAME2 backtraces-with-line-numbers, Backtraces now include file name and line number.)

    $(P The default tracehandler on linux and FreeBSD now parses DWARF
        debug info to add file names and line numbers to backtraces.
    )

    $(PRE

$(LI $(LNAME2 std-algorithm-moveEmplace, A combined `moveEmplace` was added.)

    $(P $(XREF algorithm_mutation, MoveEmplace) efficiently combines $(XREF
        algorithm_mutation, move) with $(XREF conv, emplace) thus avoids having
        to initialize and destroy a value before moving into uninitialized data.
    )

    ------
    T* moveToHeap(T)(ref T value)
    {
        import core.memory : GC;

        auto ptr = cast(T*)GC.malloc(T.sizeof);
        // move value and emplace it into ptr
        moveEmplace(value, *ptr);
        return ptr;
    }
    ------
    $(P There are also $(XREF algorithm_mutation, moveEmplaceAll)
        and $(XREF algorithm_mutation, moveEmplaceSome) as counterparts of
        $(XREF algorithm_mutation, moveAll) and $(XREF algorithm_mutation, moveSome).
    )
)

$(LI $(LNAME2 curl-dynamic-loading, libcurl is now loaded dynamically)

    $(P $(STDMODREF net_curl, std.net.curl) was changed to load curl as shared
        library at runtime.  This simplifies the usage as it's no longer
        necessary to link against libcurl or to install any development
        libraries.
    )

    $(P The implementation will also try to get the needed curl symbols from the
        executable itself. So it remains possible to link with a specific
        version of libcurl or with a static libcurl library.
    )

    $(P To make this work you have to link with $(I --export-dynamic) respectively
        use a $(I .DEF) file on Windows (see $(LINK2
        http://wiki.dlang.org/Curl_on_Windows#Using_the_static_lib, wiki) for
        more info on the latter).
