CHANGELOG.md

1.5.1

• Wrap errors so they're compatible with errors.Is and errors.As [GH-282]
• Fix map of slices not decoding properly in certain cases. [GH-266]

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]

1.3.1

• Squash should only squash embedded structs. [GH-194]

1.3.0

• Added ",omitempty" support. This will ignore zero values in the source structure when encoding. [GH-145]

1.2.3

• Fix duplicate entries in Keys list with pointer values. [GH-185]

1.2.2

• Do not add unsettable (unexported) values to the unused metadata key or "remain" value. [GH-150]

1.2.1

• Go modules checksum mismatch fix

1.2.0

• Added support to capture unused values in a field using the ",remain" value in the mapstructure tag. There is an example to showcase usage.
• Added DecoderConfig option to always squash embedded structs
• json.Number can decode into uint types
• Empty slices are preserved and not replaced with nil slices
• Fix panic that can occur in when decoding a map into a nil slice of structs
• Improved package documentation for godoc

1.1.2

• Fix error when decode hook decodes interface implementation into interface type. [GH-140]

1.1.1

• Fix panic that can happen in decodePtr

1.1.0

• Added StringToIPHookFunc to convert string to net.IP and net.IPNet [GH-133]
• Support struct to struct decoding [GH-137]
• If source map value is nil, then destination map value is nil (instead of empty)
• If source slice value is nil, then destination slice value is nil (instead of empty)
• If source pointer is nil, then destination pointer is set to nil (instead of allocated zero value of type)

1.0.0

• Initial tagged stable release.
