8.3.2

• Query properties now excpect exact object shape (based on https://github.com/crcn/sift.js/issues/152). E.g: [{a: { b: 1}}, {a: { b: 1, c: 2}}]].filter(sift({ a: { b: 1} })) === [{a: {b: 1}], and [{a: 1, b: 1}, {a: 1}]].filter(sift({ a: 1 })) === [{a: 1, b: 1}, {a: 1}].

8.0.0

• DEPRECATED indexOf in favor of array.findIndex(sift(query))
• second param is now options instead of select function. E.g: sift(query, { expressions: customExpressions, select: selectValue })
• DEPRECATED sift(query, array). You must now use array.filter(sift(query))
• Queries now expect exact object shape (based on https://github.com/crcn/sift.js/issues/117). E.g: [{a: 1, b: 1}, {a: 1}]].filter(sift({ a: 1 })) === [{a: 1}]

• Remove global *.use() function.
• converted to ES6

3.3.x

  $operator: function(a) {
    return function(b) {
      // compare here
    };
  }
});

• all operators are traversable now
• fix #58.
