fend 1.5.7

Version 1.5.7

on Rust Cargo

Changes in this version:

• Add print and println functions

  These print functions are especially useful in scripts, for example:

  #!/usr/bin/env fend
  a = "Hello World";
  println(a);
  println(5 * 5);
  

• Add exchange-rate-max-age configuration option

• Add support for simultaneously downloading currency exchange rates from
  multiple APIs, improving reliability in case the API goes offline

• Support trait implementations for random number generation

• Fix several bugs when using commas as decimal separators
