v4.6.0
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)
More robust and consistent default language detection on Windows
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 (CLI)
Support “help [OPTION]” and “help set [OPTION]” command to display description for a single set option (CLI)
Option to change language on Windows (GTK, Qt)
Minor bug fixes and feature enhancements
