Changes:

• Place expression field below history by default
• Avoid display of completion list for non-decimal numbers, text arguments, and x, y, z
• Optional custom button column in keypad (four buttons shown regardless keypad types)
• Calculate-as-you-type improvements and fixes
• Improve automatic digit groups, in input, for non-decimal numbers and group sizes other than 3
• Add --update-exchange-rates command line option
• Fix tooltips for warning and flag in result when expression is placed below history
• Hide keep above option, in preferences, on Wayland
• Improve speed of sort(), rank(), and mode() functions (and other dependent functions)
• Parse ± before implicit multiplication when not preceded by number (e.g. "7 km ± 5m")
• Always consider x^(a + b) equivalent to x^a × x^b (fixes "x^(y + z) − x^y × x^z")
• Simplify (x = a || x ≥ a + 1) and (x ≤ a || x ≥ a + 1), and similar, when x and a are integers (fixes "abs(x − 1) = abs(1 − x)")
• Do not remove duplicate whitespace characters from text strings (in quotation marks)
• Fix floating point conversion when comma is used as decimal separator
• Fix (almost) endless loop with increasingly complex equations in some cases when x + x^(1/a) is transformed to x = (b − x)^a)
• Fix and improve function() function
• Minor bug fixes and feature enhancements
