## [v3.0.0](https://github.com/reactjs/reselect/releases/tag/v3.0.0) - 2017/03/24
### New Features
Performance improvements (thanks to @johnhaley81)
Updated Typescript typings (thanks to everyone who helped)
### Breaking Changes
For performance reasons, a selector is now not recalculated if its input is equal by reference (`===`).
#### Example:
```js
import { createSelector } from 'reselect';
const mySelector = createSelector(
state => state.values.filter(val => val < 5),
values => {
console.log('calling..')
return values.reduce((acc, val) => acc + val, 0)
}
)
var createSelector = require('./dist/reselect.js').createSelector;
const mySelector = createSelector(
state => state.values.filter(val => val < 5),
values => {
console.log('calling..')
return values.reduce((acc, val) => acc + val, 0)
}
)
var state1 = {values: [1,2,3,4,5,6,7,8,9]};
console.log(mySelector(state1));
state1.values = [3,4,5,6,7,8,9];
console.log(mySelector(state1));
var state2 = {values: [1,2,3,4,5,6,7,8,9]};
console.log(mySelector(state2));
var state3 = {values: [3,4,5,6,7]};
console.log(mySelector(state3));
```
#### Output in v2.5.4:

```
#### Output in v3.0.0:

### Bug Fixes
When a selector uses defaultMemoize, if an exception is thrown for a set of arguments then the selector should also throw when called again with those arguments. (#144)

## [v2.0.0](https://github.com/reactjs/reselect/releases/tag/v2.0.0) - 2015/10/02
### Breaking Changes
#### `createSelector`, `createStructuredSelector`, and custom selector creators check arguments
Input selectors are now verified to be functions during selector creation. If verification fails an error is thrown, allowing for a useful stack trace
There is a small chance that this could cause a breaking change in code that contains a faulty selector that is never called.
## [v1.1.0](https://github.com/reactjs/reselect/releases/tag/v1.1.0) - 2015/09/16
### New features
#### `createStructuredSelector`
`createStructuredSelector` is a convenience function that helps with a common pattern when using Reselect. The selector passed to a connect decorator often just takes other selectors and maps them to keys in an object:
```js
const mySelectorA = state => state.a;
const mySelectorB = state => state.b;
const structuredSelector = createSelector(
mySelectorA,
mySelectorB,
mySelectorC,
(a, b, c) => ({
a,
b,
c
})
);
```
`createStructuredSelector` takes an object whose properties are input-selectors and returns a structured selector. The structured selector returns an object with the same keys as the `inputSelectors` argument, but with the selectors replaced with their values.
```js
const mySelectorA = state => state.a;
const mySelectorB = state => state.b;
const structuredSelector = createStructuredSelector({
x: mySelectorA,
y: mySelectorB
});
const result = structuredSelector({a: 1, b: 2}); // will produce {x: 1, y: 2}
```
## [v1.0.0](https://github.com/reactjs/reselect/releases/tag/v1.0.0) - 2015/09/09
### Breaking Changes
If upgrading from 0.0.2, see the release notes for v1.0.0-alpha
## [v1.0.0-alpha2](https://github.com/reactjs/reselect/releases/tag/v1.0.0-alpha2) - 2015/09/01
### New features
src directory included in npm package
js:next field added to package.json
## [v1.0.0-alpha](https://github.com/reactjs/reselect/releases/tag/v1.0.0-alpha) - 2015/09/01
### Breaking Changes
`createSelectorCreator` takes a user specified memoize function instead of a custom `valueEqualsFunc`.
#### Before
```js
import { isEqual } from 'lodash';
import { createSelectorCreator } from 'reselect';
const deepEqualsSelectorCreator = createSelectorCreator(isEqual);
```
#### After
```js
import { isEqual } from 'lodash';
import { createSelectorCreator, defaultMemoize } from 'reselect';
const deepEqualsSelectorCreator = createSelectorCreator(
defaultMemoize,
isEqual
);
```
### New features
#### Variadic Dependencies
Selector creators can receive a variadic number of dependencies as well as an array of dependencies.
#### Before
```js
const selector = createSelector(
[state => state.a, state => state.b],
(a, b) => a * b
);
```
#### After
```js
const selector = createSelector(
state => state.a,
state => state.b,
(a, b) => a * b
);
```
#### Access `ownProps` in Selector
Selector dependencies can receive a variadic number of parameters allowing a selector to receive `ownProps` passed from `mapToProps` in `connect`.
```js
const selector = createSelector(
(state) => state.a,
(state, props) => state.b * props.c,
(_, props) => props.d,
(a, bc, d) => a + bc + d
);
```
#### Configurable Memoize Function
```js
import { createSelectorCreator } from 'reselect';
import memoize from 'lodash.memoize';
let called = 0;
const customSelectorCreator = createSelectorCreator(memoize, JSON.stringify);
const selector = customSelectorCreator(
state => state.a,
state => state.b,
(a, b) => {
called++;
return a + b;
}
);
assert.equal(selector({a: 1, b: 2}), 3);
assert.equal(selector({a: 1, b: 2}), 3);
assert.equal(called, 1);
assert.equal(selector({a: 2, b: 3}), 5);
assert.equal(called, 2);
```
