+- Update to 4.6.1:
+  * Do not automatically by default set prefix higher than kilo for meter,
+    gram, higher than 1 (no prefix) for second and litre, or lower than 1
+    for byte and bit
+  * Do not use recently introduced SI prefixes (R, Q, r, q)
+    automatically by default
+  * Do not set automatic prefix if resulting multiplier is
+    less than 1 or greater than 1000, with some exceptions (e.g. km)
+  * Default prefix unit property (use for gram, and few other units,
+    instead of hard coded value)
+  * Option to change symbols used for output of digits 10 and 11 in
+    duodecimal numbers (use A and B as default digits)
+  * Allow the same variable left and right of the equals sign (e.g. var=var+2),
+    in variable assignment without colon, if the variable exists and the
+    previous value is known
+  * Use Unicode symbol for minus in scientific e notation
+  * Do not show multiplier if exactly 1, in HTML output of scientific notation
+  * Prefer Nm (torque) over J when the result is a vector with three components
+  * Add "amp" abbreviation to ampere unit, and "thou" name for 1/1000 in (mil)
+  * Fix unit order for Nm and Ws
+  * Fix conversion from ounce (interpreted as fluid ounce) to litre with prefix
+  * Fix automatic reactivation of global object after deletion of conflicting object
+  * Fix parsing of scientific e notation when the number is extremely large and
+    exponentiation fails because of floating point overflow
+  * Fixes for output of scientific notation using number bases other than decimal
+  * Fix prefix selection in denominator when multiplier is higher than the
+    value of the largest prefix
+  * Fix segfault in multisolve()
+  * Don't show anything on empty input
+  * Support "help [OPTION]" and "help set [OPTION]" command to display
+    description for a single set option
+  * Fix division and exponentiation of scalar by matrix/vector, e.g. 4./[8 4.5]
+  * Improve parsing of element-wise operators with comma as decimal separator
+  * Fix rref() with different units for different elements
+  * Fix segfault with empty vector in uncertainty calculation
+  * Fix segfault trying to solve cbrt(x)^(1/3)-x=0
+  * Fix segfault in handling of vector variable with uncertainty
+  * Fix internal id does not exist error
+  * Fix erroneous simplification of sin(x)^2*y-cos(x)sin(x)^2y
+  * Do not try to calculate norm() and magnitude() for matrices
+  * Fix some memory leaks
+  * Fix order of argument titles in csum() function
+
