+### Incompatible changes
+
+ - **xintcore**, **xint**, **xintfrac**: all macros deprecated at `1.2o`
+   got removed.
+
+ - **xintfrac**: addition and subtraction of `a/b` and `c/d` now use the
+   l.c.m. of the denominators. Similarly the macro supporting the modulo
+   operator `/:` uses a l.c.m for the denominator of the result.
+
+ - **xintexpr**: the addition, subtraction, modulo `/:`, and the
+   `mod()`and `divmod()` functions produce generally smaller denominators
+   (see previous item).
+
+ - **xintexpr**: formerly, the internal macros which are internally
+   associated to user-declared functions were using comma separated
+   parameter texts. They now do not use such commas (their meanings,
+   which may again change in future, are written for information to the
+   log under `\xintverbosetrue`).
+
+### Improvements and new features
+
+ - **xintexpr**: user-defined functions may now be of a recursive
+   nature. This was made possible by a refactoring of the `\xintNewExpr`
+   mechanism. It became both leaner and more extensive than formerly.
+
+ - **xintfrac**: new macros `\xintPIrr` and `\xintDecToString`. The
+   latter is a backport of a `polexpr 0.4` utility, and it is to be
+   considered unstable.
+
+ - **xintexpr**: new function `preduce()` associated with `\xintPIrr`.

+\end{everbatim*}

+\begin{everbatim*}
+\xintdefiifunc powmod(x, m, n) :=
+    if(m,
+    % m non zero (assume positive)
+       if(m=1,

+         ),
+    % m is zero, return 1
+    1);

+I have made the definition here for the |\xintiiexpr| parser; we could do the
+same for the |\xintexpr|-parser (but its usage with big powers would quickly
+create big denominators, think |powmod(1/2, 1000, 1)| for example.)

+\end{everbatim*}
+The function assumes the exponent is non-negative (the Python |pow| behaves
+the same), but zealous users will add the necessary code for negative
+exponents, after having defined another function for modular inverse!
+
+It is mandatory for such definitions to use the \func{if} function, and not
+the |(x)?{A}{B}| construct which much choose a branch. The parsing of the
+\func{if} function keeps the memory of the two alternative branches; to the
+contrary, the \emph{constructed} |powmod| function will expand \emph{only} the
+then relevant branch. This is of course absolutely needed for things such as
+the Euclide algorithm where it would be catastrophic to evaluate both branches
+as the first one involves a division by |b| and the algorithm stops only when
+|b| is actually zero.

+%
+% Comments added 2018/02/28:
+%
+% At 1.3 of February 2018, there was important refactoring. Earlier,
+% \XINT_expr_redefinemacros was a very big macro which made aliases of the
+% dozens of macros (most from xintfrac and some defined especially by xintexpr
+% for acting on csv lists primarily) involved in the expression rendering and
+% then redefined them all to expand to their original selves only when applied
+% to purely numeric arguments. At 1.3 only very few such re-definitions are
+% made, as what is redefined are a limited number of core wrapper macros.
+%
+% Only when the original macros have one or two arguments is it examined if
+% they can expand immediately (this includes case of function having possibly
+% only one, or possibly two arguments). For macros applying to three or more
+% or an undefined number of arguments, we don't complicate matters into
+% checking if expansion is possible, and we delay that expansion
+% automatically (but if() and ifsgn() do check if first argument is numeric
+% and expand to suitable branch in that case).
+%
+% In particular any function defined by \xintdeffunc or \xintNewFunction (it
+% is then basically only a macro abstraction) when used in new function
+% definitions will never be expanded immediately, because the detection of
+% whether they are applied to only numerical data has not yet been added.
+% (this might be added in future).
+%
+% Some aspects of the 1.3 refactoring have made recursive definition via
+% \xintdeffunc possible (of course they always were via \xintNewFunction as
+% the latter is but a wrapper of a standard TeX macro definition, where
+% \xintexpr parsing is not at all involved).
+%
+% A somewhat complicated layer (not modified at 1.3) is devoted to making
+% possible the parsing of constructs such as [#1..[#2]..#3][#4:#5] or
+% [#1..#2]*#3 and it seems to work. At 1.3, even esoteric construct such as
+% [divmod(#1,#2)]*#3 is parsable by \xintNewExpr. (In \xintNewFloatExpr, don't
+% forget \empty token so that square brackets are not mistaken for optional
+% argument of \xintthefloatexpr; same for \xintdeffloatfunc.)
+%
+% Side note: I wonder if I really had a good idea to define these list
+% operations [..]*foo or foo^[...] which do not seem to occur in other
+% languages with the meanings I used. And they caused me lots of efforts for
+% support at \xintNewExpr level...
+%
+% The catcode 12 dollar sign is used to signal when a macro can not be
+% expanded but would produce a csv list. Furthermore some cases require
+% f-expandable macros as the original code expanding in \xintexpr is in
+% \csname context and did not need f-expandability.
+%
+% As mentioned above, currently syntax with dummy variables can not go through
+% where the values iterated over are not explicit; and omit, abort, break
+% mechanisms are not parsable with non purely numerical data, in part because
+% they are not implemented internally via pure f-expansion.
