4.2.0

[4.2.0] - 2022-10-03

Removed:

• Removed seenRequests cache. This cache was used to de-duplicate events, but it has been supplanted with summary events.

Deprecated:

• The allowFrequentDuplicateEvents configuration has been deprecated because it controlled the behavior of the seenRequests cache.

3.7.0

[3.7.0] - 2022-10-03

4.1.1

[4.1.1] - 2022-06-07

Changed:

• Enforce a 64 character limit for application.id and application.version configuration options.

Fixed:

• Do not include deleted flags in allFlags.

4.1.0

[4.1.0] - 2022-04-21

Added:

• LDOptionsBase.application, for configuration of application metadata that may be used in LaunchDarkly analytics or other product features. This does not affect feature flag evaluations.

Fixed:

• The baseUrl, streamUrl, and eventsUrl properties now work properly regardless of whether the URL string has a trailing slash. Previously, a trailing slash would cause request URL paths to have double slashes.

3.6.0

[3.6.0] - 2022-04-21

Added:

• LDOptionsBase.application, for configuration of application metadata that may be used in LaunchDarkly analytics or other product features. This does not affect feature flag evaluations.

Fixed:

• The baseUrl, streamUrl, and eventsUrl properties now work properly regardless of whether the URL string has a trailing slash. Previously, a trailing slash would cause request URL paths to have double slashes.

4.0.3

[4.0.3] - 2022-02-16

Fixed:

• If the SDK receives invalid JSON data from a streaming connection (possibly as a result of the connection being cut off), it now uses its regular error-handling logic: the error is emitted as an error event or, if there are no error event listeners, it is logged. Previously, it would be thrown as an unhandled exception.

3.5.1

[3.5.1] - 2022-02-17

Fixed:

• If the SDK receives invalid JSON data from a streaming connection (possibly as a result of the connection being cut off), it now uses its regular error-handling logic: the error is emitted as an error event or, if there are no error event listeners, it is logged. Previously, it would be thrown as an unhandled exception.

4.0.2

[4.0.2] - 2022-01-25

Removed:

• Removed the version export which was originally a constant inserted by the Rollup build, but was no longer usable since Rollup is no longer being used. The SDKs never used this export, since they have version properties of their own; the version string of launchdarkly-js-sdk-common was never meant to be exposed to applications.

4.0.1

[4.0.1] - 2022-01-21

Changed:

• This package is now published as a regular Node module. Previously, it was published as minified bundles created by Rollup. There was no need for this since Rollup is only needed for web code, and the js-client-sdk build already runs Rollup to embed the js-sdk-common code. Using Rollup caused the platform-dependent behavior of uuid to fail because the code for only one platform (browser or Node) was embedded.

4.0.0

[4.0.0] - 2022-01-14

Changed:

• Updated uuid package to 8.x.
• In TypeScript, the property LDEvaluationDetail.reason is now nullable, which correctly reflects the fact that evaluation reasons may not always be available.

Removed:

• Removed the type NonNullableLDEvaluationReason, which was a side effect of the LDEvaluationDetail.reason being incorrectly defined before.
• Removed all types, properties, and functions that were deprecated as of the last 3.x release.
