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.
