v2.0.0-rc1

New features

• Maybe now implements Semigroup and Monoid (PR #125 by @diasbruno).
• Result now implements Semigroup.

BREAKING CHANGES

• folktale/data/future is now folktale/concurrency/future.

• folktale/data/task is now folktale/concurrency/task.

• folktale/data/conversions is now folktale/conversions.

• folktale/core/fantasy-land is now folktale/fantasy-land.

• folktale/data/maybe is now folktale/maybe.

• folktale/data/result is now folktale/result.

• folktale/data/validation is now folktale/validation.

• The folktale/core/adt module is now folktale/adt/union module, which specifies that it creates union types. The data function was also renamed to union, and the ADT namespace was renamed to Union — although this one was used mostly internally.

  Previously:

  const { data, derivations } = require('folktale/core/adt');
  
  const List = data('List', {
    Empty(){ },
    Cons(value, rest) {
      return { value, rest };
    }
  }).derive(derivations.Equality);

  Now:

  const { union, derivations } = require('folktale/adt/union');
  
  const List = union('List', {
    Empty(){ },
    Cons(value, rest) {
      return { value, rest };
    }
  }).derive(derivations.Equality);
