2.2.3

[2.2.3] - 2021-06-03

Fixed:

• Updated go-jsonstream to v1.0.1 to incorporate a bugfix in JSON number parsing.

2.2.2

[2.2.2] - 2021-01-15

Changed:

• Greatly improved the efficiency of deserializing lduser and ldvalue types from JSON when the launchdarkly_easyjson build tag is enabled, by using the EasyJSON API more directly than before. When the build tag is not enabled, these changes have no effect.

2.2.1

[2.2.1] - 2021-01-04

Fixed:

• Parsing a User from JSON failed if there was a privateAttributeNames property whose value was null. This has been fixed so that it behaves the same as if the property had a value of [] or if it was not present at all.

2.2.0

[2.2.0] - 2020-12-17

Added:

• All types that can be converted to or from JSON now have WriteToJSONWriter and ReadFromJSONReader methods that use the new go-jsonstream API for greater efficiency, although json.Marshal and json.Unmarshal still also work.

Deprecated:

• The jsonstream subpackage in go-sdk-common is now deprecated in favor of go-jsonstream. The Go SDK no longer uses jsonstream, but it is retained here for backward compatibility with any other code that may have been using it. Some types still have WriteToJSONBuffer methods for using jsonstream; these are also deprecated.

2.1.0

[2.1.0] - 2020-12-14

Added:

• IsDefined() method for ldvalue.Value, ldreason.EvaluationReason, and ldtime.UnixMillisecondTime.
• ValueArray and ValueMap types in ldvalue, for representing immutable JSON array/object data in contexts where only an array or an object is allowed, as opposed to the more general ldvalue.Value. This is mainly used by LaunchDarkly internal components but may be useful elsewhere.

Changed:

• In lduser.NewUserBuilderFromUser(), if the original user had custom attributes and/or private attributes, the map that holds that data now has copy-on-write behavior: that is, the builder will only allocate a new map if you actually make changes to those attributes.

2.0.1

[2.0.1] - 2020-10-08

Fixed:

• Trying to unmarshal a JSON null value into lduser.User now returns an error of type *json.UnmarshalTypeError, rather than misleadingly returning lduser.ErrMissingKey().
• Trying to unmarshal a JSON value of the wrong type into ldvalue.OptionalBool, ldvalue.OptionalInt, or ldvalue.OptionalString now returns an error of type *json.UnmarshalTypeError, rather than a generic error string from errors.New().
• The error lduser.ErrMissingKey() had an empty error string.

2.0.0

[2.0.0] - 2020-09-18

Initial release of the newer types that will be used in Go SDK 5.0 and above.

Added:

• Package ldlog, which was formerly a subpackage of go-server-sdk.
• Package ldlogtest, containing test helpers for use with ldlog.
• Package ldreason, containing EvaluationReason and related types that were formerly in go-server-sdk.
• Package ldtime, containing UnixMillisecondTime.
• Package lduser, containing User and related types that were formerly in go-server-sdk.
• Package jsonstream, a fast JSON encoding tool that is used internally by the SDK.
• ldvalue.OptionalString now implements encoding.TextMarshaler and encoding.TextUnmarshaler. This is not used by the Go SDK, but can be helpful when using OptionalString in other contexts.
• ldvalue.OptionalBool and ldvalue.OptionalInt are analogous to ldvalue.OptionalString, representing values that may be undefined without using pointers. These are used in the Go SDK.

Changed:

• The minimum Go version is now 1.14.
• The User type is now opaque and immutable; there is no direct access to its fields.
• The User type no longer uses pointers or interface{} internally, decreasing the need for heap allocations.
• Reading a User from JSON with json.Unmarshal now returns an error if the key property is missing or null.
• EvaluationDetail.VariationIndex is now an OptionalInt rather than an int.
• EvaluationReason is now a struct.
• This project is now a Go module, although it can still be used from non-module code.

Removed:

• In ldvalue, there are no longer methods for wrapping an existing interface{} value in a Value.
• All deprecated members of types that were moved here from go-server-sdk have been removed.

1.0.0

[1.0.0] - 2020-02-03

Initial release. This will be used in versions 4.16.0 and above of the LaunchDarkly Server-Side SDK for Go.
