+code that is going to be available only through a
+\cs{DocumentMetadata} declaration and that is\Dash most
+importantly\Dash work under development and subject to
+change without further notice. This means, that commands and interfaces provided there may
+get altered or removed again after some public testing. The code can
+be accessed through the \cs{DocumentMetadata} key \texttt{testphase}.
+Currently supported values are \texttt{phase-I} and \texttt{phase-II}
+that enable code of the tagged PDF project (phase-I is frozen and
+phase-II the phase we are currently working on). With
+\begin{verbatim}
+\DocumentMetadata{testphase=phase-II}
+\end{verbatim}
+you currently enable tagging for paragraphs and footnotes, more
+document elements will follow soon.
+
+For more detailed testing it is also possible to pass other values to
+\texttt{testphase}, for example, the first incarnation of a template
+design interface based on \pkg{l3keys} can be accessed through the
+value \texttt{prototype}, thus
+\begin{verbatim}
+\DocumentMetadata{testphase={phase-II,prototype}}
+\end{verbatim}
+will enable all of phase-II plus the draft template interface (which
+is not yet integrated in phase-II).
+
+Eventually, code will move (once considered stable) from the
+testphase into the \LaTeX{} kernel itself. Tagging will continue to
+require a \cs{DocumentMetadata} declaration, but you will then be able
+to drop the \texttt{testphase} key setting.

+\subsection{Better allocator for Lua command ids}
+
+In \LuaTeX\ we already had the \cs{newluafunction} macro which allocates
+a Lua function identifier which can be used to define commands
+with \cs{luadef}. But this always required two steps: \cs{newluafunction}
+defines the passed control sequence as an integer, which then has to be used
+to define the actual Lua command with \cs{luadef}. After that, the integer is
+no longer needed. This was inconsistent with other allocators. Therefore we
+added two new allocators \cs{newluacmd} and \cs{newexpandableluacmd} which
+directly define a control sequences invoking the allocated Lua function.
+The first one defines a non-expandable Lua command, the second one an expandable
+one. Of course, the associated Lua function still has to be defined by assigning
+a function to the \verb|lua.get_functions_table()| table. The required index is
+available in \cs{allocationnumber}.
+
+An example could be
+\begin{verbatim}
+\newluacmd \greeting
+\directlua {
+lua.get_functions_table()
+ [tex.count.allocationnumber]
+ = function()
+ local name = token.scan_argument()

\section{Code improvements}
+\subsection{\cs{protected} UTF-8 character definitions}
+The characters defined via \file{utf8.def} are now defined as \cs{protected}
+macros. This makes them safe to use in expansion contexts where the
+classic \cs{protect} mechanism is not enabled, notably L3 programming
+layer \texttt{e} and \texttt{x} arguments.
+
+Related to this change \cs{MakeUppercase} and \cs{MakeLowercase} have
+been updated to use the Unicode-aware case changing functions
+\cs{text\string_lowercase:n} in place of the \TeX-primitive \cs{lowercase}.
+A similar change will be made in the \pkg{textcase} package.

+Note for technical reasons these low level character handling changes
+will not be rolled back if the format version is rolled back using the

+The \cs{IfNoValueTF} command chooses the \meta{true code} if the optional argument has not
+been used at all (and it returns the special \texttt{-NoValue-}
+marker), but not if it has been given an empty value. In contrast
+\cs{IfBlankTF} returns true if its argument is either truly empty or
+only contains one or more normal blanks.
+For example
+\begin{verbatim}
+\NewDocumentCommand\foo{m!o}{\par #1:

+ {\IfBlankTF{#2}{Blanks in or empty}%

+ \foo{1}[bar] \foo{2}[ ] \foo{3}[] \foo{4}[\space] \foo{5} [x]
+\end{quote}
+
+Note that the \cs{space} in (4) is considered real content---because it is
+a command and not a \enquote{space} character---even though it results
+in producing a space. You can also observe in (5) the effect of the
+\texttt{!} specifier, preventing the last \cs{foo}
+from interpreting \texttt{[x]} as its optional argument.
