+# [4.2.2](https://github.com/TehShrike/deepmerge/releases/tag/v4.2.2)
+
+- `isMergeableObject` is now only called if there are two values that could be merged.  [a34dd4d2](https://github.com/TehShrike/deepmerge/commit/a34dd4d25bf5e250653540a2022bc832c7b00a19)
+
+# [4.2.1](https://github.com/TehShrike/deepmerge/releases/tag/v4.2.1)
+
+- Fix: falsey values can now be merged.  [#170](https://github.com/TehShrike/deepmerge/issues/170)
+
+# [4.2.0](https://github.com/TehShrike/deepmerge/releases/tag/v4.2.0)
+
+- Properties are now only overwritten if they exist on the target object and are enumerable.  [#164](https://github.com/TehShrike/deepmerge/pull/164)
+
+Technically this could probably be a patch release since "which properties get overwritten" wasn't documented and accidentally overwriting a built-in function or some function up the property chain would almost certainly be undesirable, but it feels like a gray area, so here we are with a feature version bump.
+
+# [4.1.2](https://github.com/TehShrike/deepmerge/releases/tag/v4.1.2)
+
+- Rolled back #167 since `Object.assign` breaks ES5 support.  [55067352](https://github.com/TehShrike/deepmerge/commit/55067352a92c65a6c44a5165f3387720aae1e192)
+
+# [4.1.1](https://github.com/TehShrike/deepmerge/releases/tag/v4.1.1)

+
+# [4.1.0](https://github.com/TehShrike/deepmerge/releases/tag/v4.1.0)

+
+# [4.0.0](https://github.com/TehShrike/deepmerge/releases/tag/v4.0.0)
+
+- The `main` entry point in `package.json` is now a CommonJS module instead of a UMD module [#155](https://github.com/TehShrike/deepmerge/pull/155)
+
+# [3.3.0](https://github.com/TehShrike/deepmerge/releases/tag/v3.3.0)
+
+- Enumerable Symbol properties are now copied [#151](https://github.com/TehShrike/deepmerge/pull/151)
+
+# [3.2.1](https://github.com/TehShrike/deepmerge/releases/tag/v3.2.1)

+
+# [3.1.0](https://github.com/TehShrike/deepmerge/releases/tag/v3.1.0)
+
+- typescript typing: make the `all` function generic [#129](https://github.com/TehShrike/deepmerge/pull/129)
+
+# [3.0.0](https://github.com/TehShrike/deepmerge/releases/tag/v3.0.0)
+
+- drop ES module build [#123](https://github.com/TehShrike/deepmerge/issues/123)
+
+# [2.2.1](https://github.com/TehShrike/deepmerge/releases/tag/v2.2.1)
+
+- bug: typescript export type was wrong [#121](https://github.com/TehShrike/deepmerge/pull/121)
+
+# [2.2.0](https://github.com/TehShrike/deepmerge/releases/tag/v2.2.0)
+
+- feature: added TypeScript typings [#119](https://github.com/TehShrike/deepmerge/pull/119)
+
+# [2.1.1](https://github.com/TehShrike/deepmerge/releases/tag/v2.1.1)

+
+# [2.0.1](https://github.com/TehShrike/deepmerge/releases/tag/v2.0.1)
+
+- documentation: fix the old array merge algorithm in the readme.  [#84](https://github.com/TehShrike/deepmerge/pull/84)
+
+# [2.0.0](https://github.com/TehShrike/deepmerge/releases/tag/v2.0.0)
+
+- breaking: the array merge algorithm has changed from a complicated thing to `target.concat(source).map(element => cloneUnlessOtherwiseSpecified(element, optionsArgument))`
+- breaking: The `clone` option now defaults to `true`
+- feature: `merge.all` now accepts an array of any size, even 0 or 1 elements
+
+See [pull request 77](https://github.com/TehShrike/deepmerge/pull/77).
+
+# [1.5.2](https://github.com/TehShrike/deepmerge/releases/tag/v1.5.2)

+
+# [1.5.0](https://github.com/TehShrike/deepmerge/releases/tag/v1.5.0)
+
+- bug fix: merging objects into arrays was allowed, and doesn't make any sense. [#65](https://github.com/TehShrike/deepmerge/issues/65) published as a feature release instead of a patch because it is a decent behavior change.
+
+# [1.4.4](https://github.com/TehShrike/deepmerge/releases/tag/v1.4.4)

+
+# [1.4.0](https://github.com/TehShrike/deepmerge/releases/tag/v1.4.0)

+# deepmerge
+
+Merges the enumerable properties of two or more objects deeply.
+
+> UMD bundle is 723B minified+gzipped
+
+## Getting Started
+
+### Example Usage
+<!--js
+const merge = require('./')
+-->
+
+```js
+const x = {
+	foo: { bar: 3 },
+	array: [{
+		does: 'work',
+		too: [ 1, 2, 3 ]
+	}]
+}
+
+const y = {
+	foo: { baz: 4 },
+	quux: 5,
+	array: [{
+		does: 'work',
+		too: [ 4, 5, 6 ]
+	}, {
+		really: 'yes'
+	}]
+}
+
+const output = {
+	foo: {
+		bar: 3,
+		baz: 4
+	},
+	array: [{
+		does: 'work',
+		too: [ 1, 2, 3 ]
+	}, {
+		does: 'work',
+		too: [ 4, 5, 6 ]
+	}, {
+		really: 'yes'
+	}],
+	quux: 5
+}
+
+merge(x, y) // => output
+```
+
+
+### Installation
+
+With [npm](http://npmjs.org) do:
+
+```sh
+npm install deepmerge
+```
+
+deepmerge can be used directly in the browser without the use of package managers/bundlers as well:  [UMD version from unpkg.com](https://unpkg.com/deepmerge/dist/umd.js).
+
+
+### Include
+
+deepmerge exposes a CommonJS entry point:
+
+```
+const merge = require('deepmerge')
+```
+
+The ESM entry point was dropped due to a [Webpack bug](https://github.com/webpack/webpack/issues/6584).
+
+# API
+
+
+## `merge(x, y, [options])`
+
+Merge two objects `x` and `y` deeply, returning a new merged object with the
+elements from both `x` and `y`.
+
+If an element at the same key is present for both `x` and `y`, the value from
+`y` will appear in the result.
+
+Merging creates a new object, so that neither `x` or `y` is modified.
+
+**Note:** By default, arrays are merged by concatenating them.
+
+## `merge.all(arrayOfObjects, [options])`
+
+Merges any number of objects into a single result object.
+
+```js
+const foobar = { foo: { bar: 3 } }
+const foobaz = { foo: { baz: 4 } }
+const bar = { bar: 'yay!' }
+
+merge.all([ foobar, foobaz, bar ]) // => { foo: { bar: 3, baz: 4 }, bar: 'yay!' }
+```
+
+
+## Options
+
+### `arrayMerge`
+
+There are multiple ways to merge two arrays, below are a few examples but you can also create your own custom function.
+
+Your `arrayMerge` function will be called with three arguments: a `target` array, the `source` array, and an `options` object with these properties:
+
+- `isMergeableObject(value)`
+- `cloneUnlessOtherwiseSpecified(value, options)`
+
+#### `arrayMerge` example: overwrite target array
+
+Overwrites the existing array values completely rather than concatenating them:
+
+```js
+const overwriteMerge = (destinationArray, sourceArray, options) => sourceArray
+
+merge(
+	[1, 2, 3],
+	[3, 2, 1],
+	{ arrayMerge: overwriteMerge }
+) // => [3, 2, 1]
+```
+
+#### `arrayMerge` example: combine arrays
+
+Combines objects at the same index in the two arrays.
+
+This was the default array merging algorithm pre-version-2.0.0.
+
+```js
+const combineMerge = (target, source, options) => {
+	const destination = target.slice()
+
+	source.forEach((item, index) => {
+		if (typeof destination[index] === 'undefined') {
+			destination[index] = options.cloneUnlessOtherwiseSpecified(item, options)
+		} else if (options.isMergeableObject(item)) {
+			destination[index] = merge(target[index], item, options)
+		} else if (target.indexOf(item) === -1) {
+			destination.push(item)
+		}
+	})
+	return destination
+}
+
+merge(
+	[{ a: true }],
+	[{ b: true }, 'ah yup'],
+	{ arrayMerge: combineMerge }
+) // => [{ a: true, b: true }, 'ah yup']
+```
+
+### `isMergeableObject`
+
+By default, deepmerge clones every property from almost every kind of object.
+
+You may not want this, if your objects are of special types, and you want to copy the whole object instead of just copying its properties.
+
+You can accomplish this by passing in a function for the `isMergeableObject` option.
+
+If you only want to clone properties of plain objects, and ignore all "special" kinds of instantiated objects, you probably want to drop in [`is-plain-object`](https://github.com/jonschlinkert/is-plain-object).
+
+```js
+const isPlainObject = require('is-plain-object')
+
+function SuperSpecial() {
+	this.special = 'oh yeah man totally'
+}
+
+const instantiatedSpecialObject = new SuperSpecial()
+
+const target = {
+	someProperty: {
+		cool: 'oh for sure'
+	}
+}
+
+const source = {
+	someProperty: instantiatedSpecialObject
+}
+
+const defaultOutput = merge(target, source)
+
+defaultOutput.someProperty.cool // => 'oh for sure'
+defaultOutput.someProperty.special // => 'oh yeah man totally'
+defaultOutput.someProperty instanceof SuperSpecial // => false
+
+const customMergeOutput = merge(target, source, {
+	isMergeableObject: isPlainObject
+})
+
+customMergeOutput.someProperty.cool // => undefined
+customMergeOutput.someProperty.special // => 'oh yeah man totally'
+customMergeOutput.someProperty instanceof SuperSpecial // => true
+```
+
+### `customMerge`
+
+Specifies a function which can be used to override the default merge behavior for a property, based on the property name.
+
+The `customMerge` function will be passed the key for each property, and should return the function which should be used to merge the values for that property.
+
+It may also return undefined, in which case the default merge behaviour will be used.
+
+```js
+const alex = {
+	name: {
+		first: 'Alex',
+		last: 'Alexson'
+	},
+	pets: ['Cat', 'Parrot']
+}
+
+const tony = {
+	name: {
+		first: 'Tony',
+		last: 'Tonison'
+	},
+	pets: ['Dog']
+}
+
+const mergeNames = (nameA, nameB) => `${nameA.first} and ${nameB.first}`
+
+const options = {
+	customMerge: (key) => {
+		if (key === 'name') {
+			return mergeNames
+		}
+	}
+}
+
+const result = merge(alex, tony, options)
+
+result.name // => 'Alex and Tony'
+result.pets // => ['Cat', 'Parrot', 'Dog']
+```
+
+
+### `clone`
+
+*Deprecated.*
+
+Defaults to `true`.
+
+If `clone` is `false` then child objects will be copied directly instead of being cloned.  This was the default behavior before version 2.x.
