 Further packages: `xintbinhex`, `xintgcd`, `xintseries` and `xintcfrac`.
 
 Main dependencies are handled automatically. For example `xintexpr`

-`gcd` and `lcm` functions in expressions require explicit loading of
-`xintgcd`, and hexadecimal notation requires explicit loading of
-`xintbinhex`.

 Package `xintcore` is the subset of `xint` providing only the five
-operations on big integers: `\xintiiAdd`, `\xintiiMul`, ... It is (by
-default) loaded by the (LaTeX only) package

+
+ - **xintexpr**: with `\xintglobaldefstrue`, `\xintdefvar`,
+   `\xintdeffunc`, `\xintNewExpr` et. al. make definitions with global
+   scope.
+
+ - **xintexpr**: `qraw()` for fast input of (very many) comma separated
+    numbers (in suitable raw format).
+
+ - **xintexpr**: the colon in the `:=` part of the syntax for
+   `\xintdefvar` and variants is now optional; and if present it may be
+   an active character or have any (reasonable) catcode.
+   
+ - **xintexpr**: `\xintdefvar`, `\xintdeffunc` and their variants try to
+   set the catcode of the semi-colon which delimits their arguments; of
+   course this will not work if that catcode is already frozen.
+
+ - `\xintUniformDeviate` is better documented and `sourcexint.pdf` is better
+   hyperlinked and includes indices for the macros defined by each package.
+
+### Bug fixes
+
+ - **xintfrac**: since `1.3` release, it loaded **xintgcd** in
+   contradiction to what the documentation says (hence also **xintexpr**
+   loaded **xintgcd** automatically). There is no actual dependency so
+   the loading is removed for now.

 non-uniformity could be obtained with only 2 calls, but paranoïa about the
 phenonemon of seeds with common bits has led me to accept the overhead of
 using the 7 high bits of 4 random 28bits integers, rather than one single
 28bits integer, or two, or three.

+\subsection{Using an expression parser within another one}

+This was already illustrated before. In the following:
+\begin{everbatim*}
+\xintthefloatexpr \xintexpr add(1/i, i=1234..1243)\relax ^100\relax
+\end{everbatim*},
+the inner sum is computed exactly. Then it will be rounded to |\xinttheDigits|
+significant digits, and then its power will be evaluated as a float operation.
+One should avoid the "|\xintthe|" parsers in inner positions as this induces
+digit by digit parsing of the inner computation result by the outer parser.
+Here is the same computation done with floats all the way:
+\begin{everbatim*}
+\xintthefloatexpr add(1/i, i=1234..1243)^100\relax
+\end{everbatim*}
+
+Not surprisingly this differs from the previous one which was exact until
+raising to the |100|th power.
+
+The fact that the inner expression occurs inside a bigger one has nil
+influence on its behaviour. There is the limitation though that the outputs
+from \csbxint{expr} and \csbxint{floatexpr} can not be used directly in
+\csbxint{theiiexpr} integer-only parser. But one can do:

 \begin{itemize}
+\item Release |1.3c| of |2018/06/17|:
+  \begin{itemize}[nosep]
+  \item \csbxint{globaldefstrue} to give global scope to definitions done by
+    \csbxint{defvar}, \csbxint{deffunc}, \csbxint{NewExpr}, et.\@ al.
+  \item \csbn{qraw()} to allow bypassing the normal mode of functioning
+    and reduce memory footprint from parsing (very many) comma separated
+    numerical items.
+  \item the colon in the |:=| part of the syntax for
+   \csbxint{defvar} and variants is now optional; and if present it may be
+   an active character or have any (reasonable) catcode.
+  \item \csbxint{defvar}, \csbxint{deffunc} and their variants try to set the
+   catcode of the semi-colon which delimits their arguments; of course this
+   will not work if that catcode is already frozen.
+  \item \csbxint{exprSafeCatcodes} sets a toggle to allow some nested usage.

+    better hyperlinked and includes indices for the macros defined by each
+    package.
