+Ddoc
 
-    $(WHATSNEW
-        $(LI core.time: Non-generic aliases for dur have been added (i.e seconds(),
-        minutes(), etc.))
-        $(LI For functions which have a version which takes a core.time.Duration
-        and another version which takes an integral value, the version which
-        takes an integral value has now been deprecated.)
-        $(LI clear() has been renamed to destroy(). clear() remains as an alias to
-        destroy() but has been scheduled for deprecation. Please use destroy()
-        instead.)
-        $(LI Exception backtracing has been implemented for FreeBSD.)
-        $(LI A FreeBSD-specific module (core.sys.freebsd.dlfcn) has been added for
-        the dlfcn.h C header for that platform.)
-        $(LI Modules for the execinfo.h C header have been added for FreeBSD, OS X,
-        and Linux (core.sys.freebsd.execinfo, core.sys.osx.execinfo, and
-        core.sys.linux.execinfo, respectively).)
-        $(LI Several core.stdc modules have been annotated with safety attributes.)
-        $(LI Most functions in core.bitop have been marked @safe pure nothrow.)
-        $(LI thread_stackBottom() and thread_stackTop() now require the current
-        thread to be attached to the runtime (with thread_attachThis()).)
-        $(LI A new atomicFence() instruction has been added to core.atomic.)
-        $(LI An experimental critical regions API has been added. See the functions
-        thread_enterCriticalRegion(), thread_exitCriticalRegion(), and
-        thread_inCriticalRegion() in core.thread. This API is not set in stone, so
-        the documentation is not yet processed by Ddoc and the interface may
-        change over time.)
-        $(LI The capacity() and reserve() functions have been marked pure nothrow.)
-        $(LI The thread_needLock() function has been removed. It was largely
-        considered useless since single core systems are very rare today (and it
-        didn't result in significant enough optimization anyway).)
-        $(LI The thread_scanAll() function now scans the calling thread's stack
-        and registers in addition to other threads'.)
-        $(LI All of core.sys.posix.pthread has been marked nothrow.)
-        $(LI A thread_setThis() function has been added to core.thread. This is a
-        low-level function primarily useful when side-stepping DRuntime's threading
-        infrastructure.)
-        $(LI Some core.stdc.stdio functions have been marked pure.)
-        $(LI Several core.memory functions have been marked pure and nothrow.)
-        $(LI core.stdc.stdarg now supports vector types.)
-        $(LI All core.sys.windows.windows functions are now nothrow. Some have been
-        marked pure as well.)
-        $(LI SYSTEM_INFO, GetSystemInfo(), and GetNativeSystemInfo() have been
-        added to core.sys.windows.windows.)
-        $(LI thread_attachThis() and thread_detachThis() are now more forgiving
-        about attaching already-attached threads and detaching already-detached
-        threads.)
-        $(LI Thread.yield() now uses SwitchToThread() on Windows.)
-        $(LI All core.atomic functions have been marked nothrow. Some have been
-        marked pure.)
-        $(LI Condition now has a mutex() property.)
-        $(LI RWMutex's reader() and writer() functions have been marked @property.)
-        $(LI 256-bit SIMD types have been added to core.simd.)
-        $(LI Exceptions will no longer trap on Windows if a debugger is attached.)
-        $(LI SetTimer() and KillTimer() have been added to core.sys.windows.windows.)
-        $(LI Fiber.reset() now has overloads that allow resetting the function.)
-        $(LI TypeInfo now has a new function rtInfo(). While this is now part of the
-        public API, the information it provides is completely internal to the runtime.)
-    )
-
-    $(RUNTIMEBUGSFIXED
-        $(LI Unlisted bug: An out of bounds error in the internal EH code has been fixed.)
-        $(LI Unlisted bug: Some infinite recursions in core.memory functions have been fixed.)
-        $(LI Unlisted bug: Fiber.reset()'s precondition has been fixed to allow State.HOLD.)
-        $(LI Unlisted bug: Some memory leaks on shutdown have been fixed.)
-        $(LI $(BUGZILLA 5206): stat_t is not the same as struct stat)
-        $(LI $(BUGZILLA 5582): Improvements to the DLL startup code)
-        $(LI $(BUGZILLA 5930): cas doesn't work when used in code compiled with -D)
-        $(LI $(BUGZILLA 6631): core.time module constructor runs AFTER main program's module constructor)
-        $(LI $(BUGZILLA 7704): RangeError when using key optainey by AA byKey() iteration)
-        $(LI $(BUGZILLA 7923): Please remove 'deprecated' from setAssertHandler())
