==========================
|

||||
* The *fixed* crate now requires rustc version 1.34.0 or later.
|
||||
* The precision is now handled when formatting fixed-point numbers;
|
||||
the precision is handled in the same way as for primitive
|
||||
floating-point numbers in the standard library.
|
||||
* The precision argument is no longer ignored handled when
|
||||
formatting fixed-point numbers; the precision should now be
|
||||
handled in the same way as for primitive floating-point numbers in
|
||||
the standard library.
|
||||
* The precision argument is no longer ignored when formatting
|
||||
fixed-point numbers; precision should now be handled the same as

|
||||
* Parsing strings now rounds to the nearest with ties rounded to
|
||||
