!!! BE CAREFUL: BREAKING CHANGES !!!

Breaking changes:

• Dropped official support for IE11.
• Upgraded to typed-function@3, see josdejong/typed-function/HISTORY.md. Thanks @​gwhitney. Most importantly:
  • Conversions now have preference over any.
  • The this variable is no longer bound to the typed function itself.
  • The properties typed.types, typed.conversions, and typed.ignore
    have been removed.
  • There are new static functions available like typed.referTo,
    typed.referToSelf, typed.addTypes, typed.addConversions.
• Implement amended "Rule 2" for implicit multiplication (#​2370, #​2460):
  when having a division followed by an implicit multiplication, the division
  gets higher precedence over the implicit multiplication when (a) the
  numerator is a constant with optionally a prefix operator (-, +, ~),
  and (b) the denominator is a constant. For example: formerly -1 / 2 x was
  interpreted as -1 / (2 * x) and now it is interpreted as (-1 / 2) * x.
  Thanks @​gwhitney.
• Drop elementwise matrix support for trigonometric functions, exp, log, gamma,
  square, sqrt, cube, and cbrt to prevent confusion with standard matrix
  functions (#​2440, #​2465). Instead, use math.map(matrix, fn).
  Thanks @​gwhitney.
• Simplify: convert equivalent function calls into operators, for example,
  add(2, x) will now be simplified into 2 + x (#​2415, #​2466).
  Thanks @​gwhitney.
• Removed the automatic conversion from number to string (#​2482).
  Thanks @​gwhitney.
• Fix #​2412: let function diff return an empty matrix when the input contains
  only one element (#​2422).
• Internal refactoring in the simplifyCore logic (#​2490, #​2484, #​2459).
  The function simplifyCore will no longer (partially) merge constants, that
  behavior has been moved to simplifyConstant. The combination of
  simplifyConstant and simplifyCore is still close to the old behavior
  of simplifyCore, but there are some differences. To reproduce the same
  behavior as the old simplifyCore, you can use
  math.simplify(expr, [math.simplifyCore, math.simplifyConstant]).
  Thanks to the refactoring, simplify is more thorough in reducing constants.
  Thanks @​gwhitney.
• Disable support for splitting rest parameters in chained calculations
  (#​2485, #​2474). For example: math.chain(3).max(4, 2).done() will now throw
  an error rather than return 4, because the rest parameter of
  math.max(...number) has been split between the contents of the chain and
  the arguments to the max call. Thanks @​gwhitney.
• Function typeOf now returns function (lowercase) for a function instead
  of Function (#​2560). Thanks @​gwhitney.

Non-breaking changes:

• Fix #​2600: improve the TypeScript definitions of simplify.
  Thanks @​laureen-m and @​mattvague.
• Fix #​2607: improve type definition of createUnit. Thanks @​egziko.
• Fix #​2608: clarify the docs on the need to configure a smaller epsilon
  when using BigNumbers.
• Fix #​2613: describe matrix methods get and set in the docs.
• Fix link to math.rationalize in the docs (#​2616). Thanks @​nukisman.
• Fix #​2621: add TypeScript definitions for count (#​2622). Thanks @​Hansuku.
• Improved TypeScript definitions of multiply (#​2623). Thanks @​Windrill.
