2.21.0

[2.21.0] - 2020-11-17

Fixed:

• The camelCaseKeys utility function is now exported as a function instead of as an object containing a camelCaseKeys function. camelCaseKeys.camelCaseKeys remains for backwards compatibility.
• Updated the LDEvaluationDetail.reason type definition to be nullable. This value will be null when LDOptions.evaluationReasons is false.

Deprecated:

• camelCaseKeys.camelCaseKeys is now deprecated-- see the note above.

2.20.2

[2.20.2] - 2020-09-14

Fixed:

• In streaming mode, when connecting to the Relay Proxy rather than directly to the LaunchDarkly streaming service, if the current user was changed twice within a short time it was possible for the SDK to revert to flag values from the previous user. (Fixed in JS SDK 2.18.1)

2.20.1

[2.20.1] - 2020-08-19

Fixed:

• Fixed an issue where change listeners would update the component state when any flag was modified, even if the client instance was configured such that it was not subscribed for the modified flag. (Thanks, clayembry!)

2.20.0

[2.20.0] - 2020-07-17

Changed:

• Updated launchdarkly-js-client-sdk version to 2.18.0, which adds the disable-sync-event-post option.

2.19.0

[2.19.0] - 2020-07-15

Added:

• Exposed LDProvider as a standalone component. (Thanks, nimi and morton!)
• A new configuration option, deferInitialization, allows LDClient initialization to be deferred until the user object is defined. (Thanks, bezreyhan!)

Fixed:

• Removed uses of String.startsWith that caused errors in Internet Explorer unless a polyfill for that function was present.

2.18.2

[2.18.2] - 2020-05-27

Fixed:

• Fixed a TypeError where TypeScript attempted to redefine the default property on withLDProvider. This issue was introduced in version 2.18.1 of this SDK. (#36)

2.18.1

[2.18.1] - 2020-05-19

Fixed:

• Updated JS SDK version to 2.17.5, to pick up bug fixes in 2.17.5, 2.17.4, 2.17.3, 2.17.2, and 2.17.1. The intended practice is to release a new React SDK patch every time there is a JS SDK patch (unless several JS SDK patches are released very close together), but this had fallen behind.

2.18.0

[2.18.0] - 2020-02-19

Note: if you are using the LaunchDarkly Relay Proxy to forward events, update the Relay to version 5.10.0 or later before updating to this React SDK version.

Added:

• The SDK now periodically sends diagnostic data to LaunchDarkly, describing the version and configuration of the SDK, the architecture and version of the runtime platform, and performance statistics. No credentials, hostnames, or other identifiable values are included. This behavior can be disabled with the diagnosticOptOut option, or configured with diagnosticRecordingInterval.

Fixed:

• Updated JS SDK dependency version to 2.17.0, which includes a fix for streaming mode failing when used with secure mode. See release notes for JS SDK 2.17.0 fror details.

2.17.1

[2.17.1] - 2020-02-11

Fixed:

• Updated JS SDK dependency version from 2.16.0 to 2.16.3 for several recent fixes. See release notes for 2.16.1, 2.16.2, 2.16.3.

Note that while some transitive dependencies have been changed from exact versions to "best compatible" versions, the dependency on js-client-sdk is still an exact version dependency so that each release of react-client-sdk has well-defined behavior.

2.17.0

[2.17.0] - 2019-12-18

Added:

• The camelCaseKeys utility function is now exposed as part of the SDK API. This function can be called from customers' code to work around the fact that ldClient functionality does not automatically camel-case keys in the same manner as the React SDK's props and hooks features.
