+<li><p>faster implementation of both integral and float square root macros.</p></li>
+<li><p>the float square root achieves <em>correct</em> (aka <em>exact</em>) rounding in arbitrary precision.</p></li>
+<li><p>modified behaviour for the <code>\xintPFloat</code> macro, used by <code>\xintthefloatexpr</code> to prettify its output. It now opts for decimal notation if and only if scientific notation would use an exponent between <code>-5</code> and <code>5</code> inclusive. The zero value is printed <code>0.</code> with a dot.</p></li>
+<li><p>the float macros for addition, subtraction, multiplication, division now first round their two operands to P, not P+2, significant places before doing the actual computation (P being the target precision). The same applies to the power macros and to the square root macro.</p></li>
+<li><p>the documentation offers a more precise (and accurate) discussion of floating point issues.</p></li>
+<li><p>various under-the-hood code improvements; the floatexpr operations are chained in a faster way, from skipping some unneeded parsing on results of earlier computations. The absence of a real inner data structure for floats (incorporating their precisions, for one) is however still a bit hair rising: currently the lengths of the mantissas of the operands are computed again by each float macro or expression operation.</p></li>
+<li><p>(TeXperts only) the macros defined (internally) from <code>\xintdeffunc</code> et al. constructs do not incorporate an initial <code>\romannumeral</code> anymore.</p></li>
