+\begin{description}
+\item[Will \xintexprname implement \texttt{exp}, \texttt{log},
+  \texttt{cos}, \texttt{sin} \dots at some point?]
+I guess so.
+\item[\xintseriesname already provides generic tools.] Right, although the
+  casual user of the \xintname bundle will not quite know how to do variable
+  reduction expandably in order to use some series or Pad\'e approximants.
+  Besides I wrote the code at the beginning of the project and perhaps I could
+  do it better now (I have not looked at it for a while). Anyhow, generic things
+  do not help much if one wants to optimize.
+\item[Optimizing? isn't \TeX's macro expansion mechanism intrinsically slow?]
+  Intensive use of \csa{numexpr} and some token manipulation algorithms
+  exploiting to the best I could \TeX{} macros with parameters grant \xintname a
+  significant speed up in expandable arithmetic on big integers compared to
+  previously available implementations. You can do some comparisons with
+  multiplication on numbers with @100@ digits or division of one of @100@ digits
+  by another of @50@ digits, for example. However expandability is antagonist of
+  speed, and I agree it is not very exciting to optimize slow things. And I was
+  disappointed last year to realize the slowness of \TeX's mouth when it has to
+  keep hundreds of tokens in cheek to mix them later with new aliments. Believe
+  me, I try not to think too much about the fact that the whole enterprise is
+  made irrelevant by Lua\LaTeX's ability to access external libraries.
+\item[Well, why isn't this \texttt{log} etc\dots thing done yet?] 
+I have to decide on the maximal precision to achieve: @24@, @32@, @48@,
+@64@,\dots ; to settle that I would need to implement some initial versions and
+benchmark them. 
+\item[Fair enough. That's the common lot. So why not yet?] I am a bit
+  overworked. It is also an opportunity to think over
+  the basic underlying mathematics, and will need devoted thinking for some not
+  insignificant amount of time. So far I didn't find the time, or rather I found
+  out good means to waste it sillily. I also anticipate that originality could
+  very 
+  well not pay off at all, so small is the window for the precision.
+\item[Any chance this could be done in time for TL2014?] No,
+  sorry.\newline Release |1.09m| of |[2014/02/26]| was the end of a cycle, and
+  this |1.09n| of |[2014/04/01]| is only for a bug fix and inclusion of this

   prefix.
 \end{itemize}
 
-\noindent Release |1.09i| (|[2013/12/18]|):
-\begin{itemize}
-\item \csbxint{iiexpr} is a variant of \csbxint{expr} which is optimized to deal
-  only with (long) integers, |/| does a euclidean quotient.
-\item |\xintnumexpr|, |\xintthenumexpr|, |\xintNewNumExpr| are renamed,
-  respectively, \csbxint{iexpr}, \csbxint{theiexpr}, \csbxint{NewIExpr}. The
-  earlier denominations are kept but to be removed at some point.
-\item it is now possible within |\xintexpr...\relax| and its variants to use
-  count, dimen, and skip registers or variables without explicit |\the/\number|:
-  the parser inserts automatically |\number| and a tacit multiplication is
-  implied when a register or variable immediately follows a number or fraction.
-\item \xinttoolsname defines \hyperref[odef]{\ttfamily\char92odef},
-  \hyperref[oodef]{\ttfamily\char92oodef},
-  \hyperref[fdef]{\ttfamily\char92fdef}. These tools are provided for the case
-  one uses the package macros in a non-expandable context, particularly
-  \hyperref[oodef]{\ttfamily\char92oodef} which expands twice the macro
-  replacement text and is thus a faster alternative to |\edef|. This can be
-  significant when repeatedly making |\def|-initions expanding to hundreds of
-  digits.
-\end{itemize}
-
-
-\noindent Release |1.09h| (|[2013/11/28]|):
-\begin{itemize}
-\item all macros of \xinttoolsname for which it makes sense are now
-  declared |\long|. 
-\end{itemize}
-
-\noindent Release |1.09g| (|[2013/11/22]|):
-\begin{itemize}
-\item package \xinttoolsname is detached from \xintname, to make tools such as
-  \csbxint{For}, \csbxint{ApplyUnbraced}, and \csbxint{iloop} available without
-  the \xintname overhead.
-\item new expandable nestable loops \csbxint{loop} and \csbxint{iloop}.
-\end{itemize}
-
-\noindent Release |1.09f| (|[2013/11/04]|):
-\begin{itemize}
-\item new \csbxint{ZapFirstSpaces}, \csbxint{ZapLastSpaces},
-  \csbxint{ZapSpaces}, \csbxint{ZapSpacesB}, for expandably stripping away
-  leading and/or ending spaces.
-\item \csbxint{CSVtoList} by default uses \csbxint{ZapSpacesB} to strip away
-  spaces around commas (or at the start and end of the comma separated list).
-\item also the \csbxint{For} loop will strip out all spaces around commas and at
-  the start and the end of its list argument; and similarly for
-  \csbxint{Forpair}, \csbxint{Forthree}, \csbxint{Forfour}.
-\item \csbxint{For} \emph{et al.} accept all macro parameters
-  from |#1| to |#9|.
-\end{itemize}
-
-
-\noindent Release |1.09e| (|[2013/10/29]|):
-\begin{itemize}
-\item new \csbxint{integers}, \csbxint{dimensions}, \csbxint{rationals} for
-  infinite \csbxint{For} loops, interrupted with \csbxint{BreakFor} and
-  \csbxint{BreakForAndDo}.
-\item new \csbxint{ifForFirst}, \csbxint{ifForLast} for the \csa{xintFor}  and
-  \csa{xintFor*} loops,
-\item the \csa{xintFor} and \csa{xintFor*} loops are now |\long|, the
-  replacement text and the items may contain explicit |\par|'s.
-\item new conditionals \csbxint{ifCmp}, \csbxint{ifInt}, \csbxint{ifOdd}.
-\item the documentation has been enriched with various additional examples,
-  such as the \hyperref[ssec:quicksort]{the quick sort algorithm illustrated} or
-  the computation of prime numbers (\autoref{ssec:primesI},
-  \autoref{ssec:primesII}, \autoref{ssec:primesIII}). 
-\end{itemize}
-
-\noindent Release |1.09c| (|[2013/10/09]|):
-\begin{itemize}
-\item added \hyperlink{item:bool}{|bool|} and \hyperlink{item:bool}{|togl|} to
-  the 
-  \csbxint{expr} syntax; also added \csbxint{boolexpr} and \csbxint{ifboolexpr}.
-\item \csbxint{For} is a new type of loop, whose replacement text inserts the
-  comma separated values or list items via macro parameters, rather than
-  encapsulated in macros; the loops are nestable up to four levels (nine
-  levels since |1.09f|),
-  and their replacement texts are allowed to close groups as happens with the
-  tabulation in alignments,
-\item \csbxint{ApplyInline} has been enhanced in order to be usable for
-  generating rows (partially or completely) in an alignment,
-\item new command \csbxint{Seq} to generate (expandably) arithmetic sequences of
-  (short) integers,
-\end{itemize}
-
-
-\noindent Release |1.09a| (|[2013/09/24]|):
-\begin{itemize}
-\item \csbxint{expr}|..\relax| and
-  \csbxint{floatexpr}|..\relax| admit functions in their
-  syntax, with comma separated values as arguments, among them \texttt{reduce,
-    sqr, sqrt, abs, sgn, floor, ceil, quo, rem, round, trunc, float, gcd, lcm,
-    max, min, sum, prd, add, mul, not, all, any, xor}.
-\item comparison (|<|, |>|, |=|) and logical (\verb$|$, |&|) operators.
-\item \csbxint{NewExpr} now works with the standard macro parameter character
-  |#|. 
-\item both regular |\xintexpr|-essions and commands defined by |\xintNewExpr|
-  will work with comma separated lists of expressions,
-\item new commands \csbxint{Floor}, \csbxint{Ceil}, \csbxint{Maxof},
-  \csbxint{Minof} (package \xintfracname), \csbxint{GCDof}, \csbxint{LCM},
-  \csbxint{LCMof} (package \xintgcdname), \csbxint{ifLt}, \csbxint{ifGt},
-  \csbxint{ifSgn}, \csbxint{ANDof}, ...
-\item The arithmetic macros from package \xintname now filter their operands via
-  \csbxint{Num} which means that they may use directly count registers and
-  |\numexpr|-essions without having to prefix them by |\the|. This is thus
-  similar to the situation holding previously but with \xintfracname loaded.
