## 1.5.0
* New option `IgnoreUntaggedFields` to ignore decoding to any fields
without `mapstructure` (or the configured tag name) set [GH-277]
* New option `ErrorUnset` which makes it an error if any fields
in a target struct are not set by the decoding process. [GH-225]
* New function `OrComposeDecodeHookFunc` to help compose decode hooks. [GH-240]
* Decoding to slice from array no longer crashes [GH-265]
* Decode nested struct pointers to map [GH-271]
* Fix issue where `,squash` was ignored if `Squash` option was set. [GH-280]
* Fix issue where fields with `,omitempty` would sometimes decode
into a map with an empty string key [GH-281]
## 1.4.3
* Fix cases where `json.Number` didn't decode properly [GH-261]
## 1.4.2
* Custom name matchers to support any sort of casing, formatting, etc. for
field names. [GH-250]
* Fix possible panic in ComposeDecodeHookFunc [GH-251]
## 1.4.1
* Fix regression where `*time.Time` value would be set to empty and not be sent
to decode hooks properly [GH-232]
## 1.4.0
* A new decode hook type `DecodeHookFuncValue` has been added that has
access to the full values. [GH-183]
* Squash is now supported with embedded fields that are struct pointers [GH-205]
* Empty strings will convert to 0 for all numeric types when weakly decoding [GH-206]
## 1.3.3
* Decoding maps from maps creates a settable value for decode hooks [GH-203]
## 1.3.2
* Decode into interface type with a struct value is supported [GH-187]
