 ## Changes
 
+### News for LolRemez 0.4:
+
+ - Allow expressions in the range specification: `-r -pi/4:pi/4` is now valid.
+ - Allow using “pi” and “e” in expressions, as well as “π”.
+ - Bugfixes in the expression parser.
+ - Support for hexadecimal floats, *e.g.* `0x1.999999999999999ap-4`.
+ - New `--float`, `--double` and `--long-double` options to choose precision.
+ - Trim down DLL dependencies to allow for lighter binaries.
+
 ### News for LolRemez 0.3:
 
  - implemented an expression parser so that the user does not have to
